- 〔Major achievements〕No-tillage intercropping with a robotic mower: Advancing a high productivity, low-carbon and energy-efficient organic farming system
Qiliang Huang; Kai Someya; Ratih Kemala Dewi; Masakazu Komatsuzaki, Last, Solar-powered farm machinery enhances sustainable agriculture by reducing greenhouse gas emissions. Its integration into no-tillage (NT) systems may further enhance environmental benefits and organic farming viability. While intercropping improves productivity and resource efficiency, its sustainability when combined with NT and solar-powered machinery remains unclear. This study evaluates NT and intercropping with solar-powered machinery in organic cherry tomato production. A split-plot field experiment compared two tillage methods [NT and rotary tillage (RT)] and two cropping patterns [cherry tomato/peanut intercropping (TP) and monocropping (M)]. Solar-powered robotic mowers replaced conventional mowers in NT to enhance environmental benefits. Sustainability was assessed through crop productivity, energy efficiency, carbon footprint, and economic profitability. NT reduced fossil fuel and labor use, lowering energy input by 63.1 % compared to RT. NT-TP further improved yields, achieving 13.8 % higher total output than NT-M. Despite higher seed and labor inputs, NT-TP enhanced energy efficiency and profitability due to increased yield. It also improved carbon sequestration, raising soil organic carbon by 1.5 % and partially offsetting carbon emissions, leading to the lowest carbon footprint (816.9 kg CO2 eq ha−1). These findings demonstrate NT-TP's potential to enhance yield, energy efficiency, and profitability while reducing the carbon footprint, being a sustainable management for organic farming.

明治大学農学部研究報, Mar. 2024 - 〔Major achievements〕Addition of biochar decreased soil respiration in a permanent no-till cover crop system for organic soybean production
Ratih Kemala Dewi; Yingting Gong; Qiliang Huang; Peiran Li; Rahmatullah Hashimi; Masakazu Komatsuzaki, Last, The increase in soil carbon sequestration under long-term no-till (NT) and cover crop management has been shown to form part of a sustainable agricultural management practice system. Along with the increase in soil organic carbon (SOC), soil respiration in this system was also enhanced by the increased soil temperature through the decomposition that causes carbon loss from the soil. To overcome this issue, biochar can be applied. However, the addition of biochar into this system is not well studied. Therefore, the aim of this study was to investigate the effect of this system on soil respiration. The experiment was conducted at the Center for International Field Agriculture Research & Education, Ibaraki University. Long-term tillage practices, such as NT and moldboard plowing (MP), cover crops such as rye (RY) and fallow (FA), and biochar application such as with biochar (WB) and no biochar (NB) were applied to a split–split plot in a randomized complete block design with four replications. The daily CO2 flux was measured every week at 9:00–11:00 a.m. The daily soil respiration was affected by tillage and cover crop with NT practice had significantly higher daily CO2 flux than that of MP (23.8%–107.4% and 38.0%–107.8%), while RY had higher flux than that of FA (11.9%–81.2% and 34.9%–65.4%) in 2020 and 2021 soybean growing season, respectively. Additionally, in the 2020 cover crop growing season RY also increased daily CO2 flux approximately 41.8%–88.2% compared to FA. Biochar addition significantly reduced soil respiration in soybean and cover crop seasons compared to NB by 24.0%–50.7% and by 25.9%–48.3%, respectively. This reduction in soil respiration by the biochar decreased annual CO2 emissions by 17.6% and 13.0% in 2020 and 2021. The values of these emissions ranged from 9.6 Mg ha−1 for MP FA WB to 18.9 Mg ha−1 for MP RY NB in 2020 and from 7.5 Mg ha−1 for MP FA WB to 13.7 Mg ha−1 for NT FA NB in 2021. This study highlights the crucial role of biochar in reducing soil respiration and enhancing SOC sequestration. The addition of biochar into this system was able to reduce soil respiration by regulating the soil temperature, soil moisture, and protect the SOC from decomposition. Biochar addition also increased the SOC and decreased the soil bulk density, which improves soil porosity. Therefore, these findings would be very useful to be included within the global scenario of soil organic matter management.
Soil and Tillage Research, Mar. 2024, [Reviewed] - 〔Major achievements〕Modeling long-term transfers of radiocesium in farmland under different tillage and cover crop treatments
Peiran Li; Yingting Gong; Taku Tanaka; Yves Thiry; Qiliang Huang; Masakazu Komatsuzaki, Last, The 2011 nuclear accident at Japan's Fukushima Daiichi Nuclear Power Plant (FDNPP) prompted inquiries about the long-term transfer of Cesium-137 (137Cs) from soil to agricultural plants. In this context, numerical modeling is particularly useful for the long-term evaluation of the consequences of agroecosystem contamination. Agricultural practices, such as tillage and cover cropping, play key roles in 137Cs recycling in agroecosystems. In this study, we used 10-year monitoring data to develop a dynamic model to predict 137Cs redistribution (via uptake, litterfall, translocation, and percolation) under different tillage (no-tillage, NT; rotary cultivation, RC; moldboard plow, MP) and cover crop (rye; hairy vetch; fallow weed) treatments. The verification exercise and assessment results indicated the model's reliability, as the temporal dynamics of predicted values agreed with observed values. Tillage significantly influenced the 137Cs distribution in soil, thereby decreasing plant uptake of 137Cs, whereas cover crop exerted a minimal effect on 137Cs cycling. Furthermore, while the 137Cs concentrations in soybean grain under RC and NT treatments were comparable 62 years after the FDNPP accident, the concentration under MP treatment remained consistently the lowest. Despite natural decay being the main cause of the decreased global 137Cs level in the agroecosystem, with minimal losses from percolation to deeper soil layers and soybean harvesting, adopting an appropriate tillage practice was shown to promote a long-term reduction of 137Cs concentration in crops. Finally, to improve the model's accuracy, further research should consider incorporating the effects of soil properties and extreme weather events on 137Cs flow into the model, as these factors are essential for realizing improved agroecosystem predictions.
Science of the Total Environment, 10 Jan. 2024, [Reviewed] - No-tillage and rye cover crop systems improve soil water retention by increasing soil organic carbon in Andosols under humid subtropical climate
Rahmatullah Hashimi; Qiliang Huang; Ratih Kemala Dewi; Junko Nishiwaki; Masakazu Komatsuzaki, Last, No-tillage (NT) combined with a cover crop is a climate-smart agricultural practice that eliminates nearly all physical disturbance of the soil surface and increases soil aggregation and soil organic carbon (SOC); however, the response of SOC and soil water retention (SWR) to long-term NT and cover crops systems in the volcanic ash Andosol soil of Japan has not been well addressed. This study aimed to evaluate the effect of NT and moldboard plow (MP) tillage systems combined with rye (RY) and fallow (FA) cover crop treatments on SOC, active carbon (AC), water-stable aggregates, aggregate stability index, mean weight diameter (MWD), bulk density, aggregate-associated carbon, and SWR. NT significantly increased the > 4 and 2 mm aggregates, aggregate-associated C at the 0–2.5 and 2.5–5 cm depths, field capacity, and SWR between 0 and 15 cm. RY cover crops significantly increased aggregate-associated carbon at the 2.5–5 and 5–10 cm depths in both NT and MP and SWR at the 10–15 cm depth. NT combined with RY significantly increased SOC and AC in the surface layer and volumetric water content at all soil depths. Path analysis revealed that SOC and MWD were correlated with easily plant-available water (EPAW) and field capacity under the NT system and is the primary reason for the observed increase in SWR. Thus, the NT system increased plant residue, reduced soil evaporation, increased SOC content and SWR, and bonded soil microaggregates into macroaggregates better than the MP system. The use of an RY-based NT system is an effective climate-smart agriculture practice that reduces the drought effects brought on by climate change.
Soil and Tillage Research, Oct. 2023, [Reviewed] - Enhancing energy efficiency and reducing carbon footprint in organic soybean production through no-tillage and rye cover crop integration
Qiliang Huang; Yingting Gong; Ratih Kemala Dewi; Peiran Li; Xiaolong Wang; Rahmatullah Hashimi; Masakazu Komatsuzaki, Last, Organic agriculture has the potential to contribute to environmental conservation, although its impact varies depending on management practices. To investigate the effects of no-tillage (NT) combined with a rye (RY) cover crop on energy efficiency and carbon footprint (CF) in soybean production, a four-year experiment was conducted. Three tillage methods [moldboard plowing (MP), NT, and rotary tillage (RT)] and two cover crop treatments [fallow (FA) and RY] were compared. NT had 39.6% and 34.0% lower energy input compared with MP and RT, respectively, due to reduced fossil fuel consumption. However, NT also showed decreased soybean yield compared with MP and RT. Nonetheless, RY cover crop management mitigated yield reduction in the NT system, with the yield of NT-RY being 20.4% higher than that of NT-FA, although not significantly different. NT-RY exhibited the highest energy use efficiency, with high energy outputs from yield and low energy inputs. Moreover, NT-RY resulted in a 3.5% increase in soil organic carbon stock, offsetting total carbon dioxide (CO2) equivalent emissions, leading to the lowest CF (−1892.99 kg CO2 eq ha−1) and yield-scaled CF (−1.44 kg CO2 eq kg−1) among all treatments. Therefore, NT-RY management, with its high yield and energy efficiency and low CF, has the potential to be an environmentally friendly and sustainable cropping system for achieving cleaner agricultural practices in organic farming.

Japanese Journal of Human Animal Relations, 07 Mar. 2023, [Reviewed] - 〔Major achievements〕Impact of no‐tillage on soil quality and crop yield in Asia: A meta‐analysis.
Hashimi; R.; Kaneko; N.; & Komatsuzaki; M., Last, No-tillage (NT) (or zero-tillage) has been widely used to mitigate the adverse effects caused by intensive tillage. However, the long-term effectiveness of NT is highly dependent on agriculture field management, soil type, and climatic conditions. NT under different climatic condition fluctuations and soil conditions has not also been considered adequately in Asia. Furthermore, the high demand for food production in Asia requires a deeper understanding of the impact of NT on soil properties and crop production. Therefore, this meta-analysis was conducted using 64 peer-reviewed articles to evaluate the effects of NT on soil organic carbon (SOC), soil carbon storage, mean weight diameter (MWD), bulk density, water-stable aggregates, water content, other soil chemical properties, and yield responses. Our results showed that NT significantly increased SOC content overall than conventional tillage (CT). Likewise, as observed at a 0–10 cm soil depth, SOC content significantly increased by 77.0% in NT compared to CT. Alternatively, although overall, NT favoured the accumulation of soil C by 53.2% than CT, and this difference was even more impressive at the 0–10 cm layer by 77.0% than CT. Moreover, overall NT significantly increased MWD, soil available P, and >2 mm aggregates than CT. In contrast, even though NT did not significantly decrease smaller than the 0.25 mm aggregates than CT in the 0–10 cm layer, NT increased exchangeable K by 81.0% than CT. Results also showed that while NT and CT had no significant effects on crop yield, NT slightly increased soybean and wheat yield, and CT increased rice and maize yield than NT. Based on these results, NT is proposed as a promising practice to enhance soil quality and is plausible to increase crop yield in Asia., Wiley Online Library

Agronomy, Feb. 2022, [Reviewed] - Soil carbon sequestration and soil quality change between no-tillage and conventional tillage soil management after 3 and 11 years of organic farming
Dewi, R.K.; Fukuda, M.; Takashima, N.; Yagioka, A.; Komatsuzaki, M., Last, The aim of this study was to evaluate the long-term effect of no-tillage systems in organic farming on soil,carbon sequestration and soil quality, which is associated with nutrient availability. The experiment was,10 conducted on a low-input organic farm since 2009, using a randomized complete block design with four,replications. Two treatments, conventional tillage (CT) and no-tillage (NT), were tested. Soil samples were,obtained after crops were harvested in 2012 and 2020 from four different soil depth layers between 0‒,30 cm, and the physical and chemical properties of soil samples were measured. Data were analyzed,using ANOVA with Tukey tests (α = 0.05), while the correlation was analyzed based on Pearson correla-,15 tion. At 0–2.5 cm and 2.5–7.5 cm depths, soil bulk density (BD) in the NT treatment was 30% and 8%,lower, respectively, in 2012, and 25% and 14% lower, respectively, in 2020 compared with the CT,treatment. The NT treatment could enhance the soil organic carbon (SOC) better than CT treatment at,the same depth, sequestering a greater amount of carbon in the soil. Compared with the CT treatment,,SOC concentration in the NT treatment was 76% and 12% higher, respectively, in 2012, and 103% and,20 38% higher, respectively, in 2020. In 2012, the SOC stock showed a significant difference between NT and,CT treatments only at the 0–2.5 cm soil depth, with the value being 24% higher in the NT treatment than,in the CT treatment. However, in 2020, the SOC stock was 50% and 19% higher in the NT treatment than,in the CT treatment at 0–2.5 cm and 2.5–7.5 cm depths, respectively. The SOC also could significantly,expand cation exchange capacity (CEC) and the availability of some nutrients in the soil. However, the,25 relationship between was weak in 2020. Moreover, the NT treatment showed better progression of,humification than CT. Finally, long-term NT systems in low-input organic farming could reduce soil bulk,density and enhance soil carbon sequestration and soil quality. However, this system must be complemented,with the conventional approach to maintain nutrient balance for long-term management., Tayer&Francis
Soil Science and Plant Nutrition, 2022, [Reviewed] - Response of weeds and rice yield to Italian ryegrass as a cover crop and planting density in organic farming
Matsuoka, T.; Asagi, N.; Komatsuzaki, M., Last, Organic farming has been receiving increased attention in the agriculture sector; however, Japanese organic farming often requires intensive labor, and the yield is lower compared with the conventional rice system. In this study, we examined the effects of planting density (12.7 vs. 24.2 plant m−1) and cover crop (Italian ryegrass [Lolium multiflorum] vs. winter fallow) on organic rice production in central Japan. A 2-year experiment was conducted under organic management in a paddy field at the Center for International Field Agriculture Research & Education, Ibaraki University in 2019 and 2020 using a split-plot design with four replications. Rice yields were 25% and 6.8% higher when Italian ryegrass was used as the cover crop under sparse planting conditions than under dense planting conditions in 2019 and 2020, respectively. The interaction between cover crop and planting density was significant across the 2 years. Although there was no significant difference in weed biomass during the rice cultivation period, sparse planting and winter fallow resulted in greater weed biomass than dense planting and Italian ryegrass, respectively. The contribution of nitrogen (N) derived from Italian ryegrass showed a significant difference between 2019 and 2020 but not between sparse and dense planting. Although cover crop-derived N contribution to organic rice production was different between the 2 years, the use of Italian ryegrass as a cover crop at sparse planting density can improve rice yield and suppress weed growth in central Japan., Wiley Online Library
Agronomy Journal, 2022, [Reviewed] - Rice Height Monitoring between Different Estimation Models Using UAV Photogrammetry and Multispectral Technology
Wenyi Lu; Tsuyoshi Okayama and Masakazu Komatsuzaki, Unmanned aerial vehicle (UAV) photogrammetry was used to monitor crop height in a flooded paddy field. Three multi-rotor UAVs were utilized to conduct flight missions in order to capture RGB (RedGreenBlue) and multispectral images, and these images were analyzed using several different models to provide the best results. Two image sets taken by two UAVs, mounted with RGB cameras of the same resolution and Global Navigation Satellite System (GNSS) receivers of different accuracies, were applied to perform photogrammetry. Two methods were then proposed for creating crop height models (CHMs), one of which was denoted as the M1 method and was based on the Digital Surface Point Cloud (DSPC) and the Digital Terrain Point Cloud (DSPT). The other was denoted as the M2 method and was based on the DSPC and a bathymetric sensor. An image set taken by another UAV mounted with a multispectral camera was used for multispectral-based photogrammetry. A Normal Differential Vegetation Index (NDVI) and a Vegetation Fraction (VF) were then extracted. A new method based on multiple linear regression (MLR) combining the NDVI, the VF, and a Soil Plant Analysis Development (SPAD) value for estimating the measured height (MH) of rice was then proposed and denoted as the M3 method. The results show that the M1 method, the UAV with a GNSS receiver with a higher accuracy, obtained more reliable estimations, while the M2 method, the UAV with a GNSS receiver of moderate accuracy, was actually slightly better. The effect on the performance of CHMs created by the M1 and M2 methods is more negligible in different plots with different treatments; however, remarkably, the more uniform the distribution of vegetation over the water surface, the better the performance. The M3 method, which was created using only a SPAD value and a canopy NDVI value, showed the highest coefficient of determination (R2) for overall MH estimation, 0.838, compared with other combinations., MDPI
Remote Sensing, 24 Dec. 2021, [Reviewed] - Methane fermentation residue compost derived from food waste to aid komatsuna (Brassica rapa) growth
Santi, N.; Dewi, R.K.; Suganuma, Y.; Iikubo, T.; Seki, H.; Komatsuzaki, M., Corresponding, One suitable solution to achieve sustainable development goals (SDGs) is to utilize methane fermentation residue obtained from food waste. However, methane fermentation residue compost is often difficult to use due to its inhibitory properties and pungent smell. To evaluate chemical parameters and plant growth, we examined the use of methane-fermented food waste residue compost (FWM), three types of animal manure, namely, horse manure (HM), cow manure (CWM), and chicken manure (CKM). Our results revealed that mixing food waste compost with cow and horse manure reduced the inhibition of Komatsuna germination, however, chicken manure blending limited inhibition reduction. The improvement of GI in the combination of FWM and animal manure was obtained at a ratio 1:4 with an improvement in GI of 20.8%, 16.8%, and 3.8% for combination FWM + HM, FWM + CWM, and FWM + CKM, respectively. The ratio of the combination of FWM + HM could be increased to a ratio of 2:3 with an improvement of 14.7%. Additionally, for Komatsuna growth, FWM with cow and horse manure mixer considerably enhanced plant growth and yield. Furthermore, the combination of FWM + HM and FWM + CWM could improve the ratio of NUE compost/NUE FWM with the values being 12.0 and 11.1, respectively. Therefore, combining FWM with CWM and HM increases the utility value of methane fermentation residues obtained from food waste as compost for maintaining soil fertility, while reducing the use of chemical fertilizer., MDPI

環境放射能除染学会誌, 06 Oct. 2021, [Reviewed] - Effect of Intertillage in the Medical Peony Cultivation and Grass Managements,on Paeoniflorin Content and Yield
Hiroichi SEKI; Morifumi HASEGAWA and Masakazu KOMATSUZAKI, Last, In the cultivation of the medical peony (Paeonia,lactiflora Pallas), effect of inter-tillage in the medical,peony cultivation and grass managements on,paeoniflorin ingredient and yield was investigated.,The experiment was conducted on cultivation and,grass managements at Tsukuba medicinal herb,research institute Tsukuba Peony Garden. From the,result, inter-tillage management substantially reduced,weed biomass compared with grass management,and the yield of peony and content of paeonifrorin,were different between the inter-tillage and the,grass management. In the field experiment that,grew second-year peony, there was no significant,difference in paeoniflorin content in August, 2014.,Positive correlations between dry weight of root and,aboveground dry weight, and between paeoniflorin,content and weed biomass were observed. And,paeoniflorin content and yields were both higher,in the grass management than in the inter-tillage,in November, 2014. In the field that grew 5 yearpeony,,paeoniflorin content was higher in the grass,management, and root dry weight was higher in the,inter-tillage in October, 2017.,Negative correlations between root dry weight,and aboveground dry weight, and between weed,biomass and root dry weight were found in 2017.,Positive correlation between paeoniflorin content,and weed biomass was also observed. In the grass,management, paeoniflorin content tended to increase,because of the competition between peony and weed,grass.

Metabolites are shown to play important roles in biological communication, but there still remain a large number of metabolites in soil to be uncovered. Metabolomics, a technique for the comprehensive analysis of metabolites in samples, may uncover the molecules that intermediate these interactions. We conducted a multivariate analysis using liquid chromatography (LC)-mass spectrometry (MS)-based untargeted metabolomics in several soil samples and also targeted metabolome analysis for the identification of the candidate compounds in soil. We identified okaramine A, B, and C in the rhizosphere soil of hairy vetch. Okaramines are indole alkaloids first identified in soybean pulp (okara) inoculated with Penicillium simplicissimum AK-40 and are insecticidal. Okaramine B was detected in the rhizosphere from an open field growing hairy vetch. Okaramine B was also detected in both bulk and rhizosphere soils of soybean grown following hairy vetch, but not detected in soils of soybean without hairy vetch growth. These results suggested that okaramines might be involved in indirect defense of plants against insects. To our knowledge, this is the first report of okaramines in the natural environment. Untargeted and targeted metabolomics would be useful to uncover the chemistry of the rhizosphere., Frontiers
Frontiers in genetics, 24 Feb. 2020, [Reviewed] - Morphological analysis on comparison of organic and chemical fertilizers on grain quality of rice at different planting densities
Kifayatullah Kakar; Youji Nitta; Naomi Asagi; Masakazu Komatsuzaki; Fumitaka Shiotsu; Toshiaki Kokubo; Tran Dang Xuan, Effects of organic (Italian ryegrass and Bokashi) and chemical fertilizer on growth, yield, and grain quality of rice (Oryza sativa L.) were compared under different planting densities in 2013/2014 and 2014/2015. Italian ryegrass was incorporated into the soil as green manure. Bokashi (a mixture of organic materials) was applied as basal dressing. To measure yield and its components, 30 hills were chosen for each treatment. Rice grains were harvested from each treatment to assess the grain quality and to evaluate accumulation structures using a scanning electron microscope. Bokashi treatment increased panicle number per hill, ripened grain percentage, panicle number per m2, and grain yield compared to no fertilizer treatment at normal planting density. Chemical fertilizer treatment increased plant length at high planting density. Italian ryegrass and Bokashi treatments promoted the taste point (taste score as reference) by reduction of amylose and protein contents at normal planting density in contrast to chemical fertilizer. 1000-grain weight, panicle number per m2, and grain yield were higher at high planting density than at normal planting density. However, high planting density decreased panicle number per hill and spikelet number per panicle. It also enhanced the amylose content of rice grain. Scanning electron microscopic observation revealed that chemical fertilizer treatment marked up protein bodies and their traces on amyloplasts. However, Bokashi treatment produced large amyloplasts, which included many starch granules. These results show that Italian ryegrass and Bokashi can offset reductions of chemical fertilizer and can lead to sufficient starch accumulation structures in rice grains., Taylor and Francis Ltd.

Tiejun Zhao; Kenshi Sakai; Tatsuya Higashi; Masakazu Komatsuzaki; Xujun Ye, Soil nitrogen content has very important influence on soil parameters and crop productions, so the soil nitrogen monitoring and management are urgently required to satisfy the demand for precision agriculture. This research is aimed to develop the simple and low cost monitoring methods to determine the soil nitrogen pools using hyper spectral camera in Andisols soil. Partial least square regression (PLSR) with cross-validation was used to calibrate the spectral data. The research estimated the potential of soil nitrogen qualitative analysis using visible (VIS) spectrographs, near infrared (NIR) spectrographs and combination of these two spectrographs. Results showed that model assessment accuracy by V10 (360nm-1010nm) spectrograph is higher than by N17E (900nm-1700nm) spectrograph. In addition, combining these two spectrographs increased the model prediction accuracy. Evaluation index (EI) test was employed in this research, and the results showed that prediction is acceptable to use of practical to predict soil nitrogen content., IEEE Computer Society
Workshop on Hyperspectral Image and Signal Processing, Evolution in Remote Sensing, 23 Oct. 2017, [Reviewed] - Cover crops reduce nitrogen leaching and improve food quality in an organic potato and broccoli farming rotation
M. Komatsuzaki, Summer cover crops may be an effective management option for scavenging residual soil nitrogen (N) when used in conjunction with crop rotation. The objective of this study was to investigate the ability of summer cover crops to reduce N leaching and to examine the effect on the yield and food quality in an organic potato (Solanum tuberosum L.) and broccoli (Brassica oleracea L.) farming rotation system. Conventional production systems were also compared with the organic system over a two-year field research period. We examined two farm management systems (conventional and organic), three cover crop regimes (summer fallow, Japanese millet [Echinochloa esculenta A. Braun], and sorghum [Sorghum bicolor L.]), and three fertilizer application levels (no input, 50% reduction of nutrient input, and conventional input) in potato and broccoli production from 2003 to 2004. Aboveground N accumulation was 13.9 to 41 kg N ha(-1) in a summer cover crop of sorghum, 10.1 to 33.7 kg N ha(-1) in millet, and only 0.4 to 0.8 kg N ha(-1) in summer fallow plants after the potato harvest, although the N accumulation differed between the Organic and conventional system. As the cover crop N accumulation increased, residual soil inorganic N in the top 90 cm of soil depth was reduced. Broccoli yields did not differ significantly in response to different summer cover crops or different levels of fertilizer application. However, a summer cover crop significantly reduced the nitrate (NO3-) concentration in broccoli heads, and the degree of NO3- reduction was significantly affected by type and concentration of fertilizer. These results revealed that summer cover crops significantly prevented N leaching and improved broccoli food quality., SOIL WATER CONSERVATION SOC
JOURNAL OF SOIL AND WATER CONSERVATION, Sep. 2017 - Dynamics of nitrogen derived from hairy vetch applied as cover crop in tomato production in plastic house
Y. Sugihara; H. Ueno; T. Hirata; M. Komatsuzaki; H. Araki, Fresh market tomatoes (Solanum lycopersicum L.) are mainly grown in plastic house in Japan and usually a large amount of nitrogen fertilizer was applied for getting high yield. One of the ways to establish an organic system, no chemical N fertilizer, is the use of cover crops. The application effect of a legume cover crop, hairy vetch (Vicia villosa R., HV), on N dynamics in fresh market tomatoes, 'House Momotaro', was investigated using the 15N-labeling method in 2011 and 2012. Before transplanting of tomato, the 15N-labeled HV (1.319 mg N pot-1, 260 kg N ha-1), and chemical N fertilizers were incorporated into the soil. Tomato seedlings were transplanted into a 1/2000 a Wagner pot with 0 and 240 kg ha-1 of N application (N0HV and N240HV) in plastic house early June, 2011. Only 240 kg ha-1 of N fertilizer was applied in conventional plot. There was no significant difference in fruit yield among the plots. In organic plot, N0HV, total N uptake in tomato plant was smaller than that in N240HV, however, the rate of N uptake derived from HV to total N uptake in tomato plants (%Ndfhv) in N0HV (37.1%) was larger than that in N240HV (24.8%) at 12 weeks after transplant. Nitrogen use efficiency from HV-derived N (NUE; N uptake derived from HV in tomato/amount of N applied in HV) was 44.4% in N240HV and 49.4% in N0HV. About half of HV-N including organic and inorganic type remained in the soil. Tomato was cultivated in the soil used 2011 with unlabelled HV and N fertilizer in 2012. There was no difference in the uptake amount of N derived from HV applied in 2011 (HV2011) into tomato between N240HV and N0HV, 57.7 mg plant-1 on average, so nitrogen use efficiency (NUE) derived from HV2011 was 4.4% on average 2012. It was recognized HV could be available for not only short-term N source, but also long-term N source.

Nugrahaning Sani Dewi; Masakazu Komatsuzaki; Yuriko Yamakawa; Hiromi Takahashi; Saori Shibanuma; Takeshi Yasue; Tsuyoshi Okayama; Atsushi Toyoda; Hikari Shimonishi; Seiichi Sasaki, The study focuses on psychological and physical effects of stress while performing community garden activities of various intensity levels. The aim of this study was to determine the psychological and physical effects in adults with (case group) and without (control group) mental disabilities. Salivary alpha-amylase (sAA) levels and the stress response scale (SRS-18) were used for the psychological analysis (n = 42). For physical assessment (n = 13), electrocardiogram (ECG), surface electromyogram (sEMG), and respiration rate were continuously measured while performing the activities using a multichannel telemetry system. The results showed that following the activities, the case group exhibited decreasing sAA levels while control group exhibited increasing sAA levels. However, both groups exhibited lower SRS-18 results following the activities. Compared with the control group, the case group had a significantly lower increase in the ratio of the heart rate (IRHR) (5.5%) during low-intensity work (filling pots with soil), but a significantly higher IRHR (16.7%) during high-intensity work (turning over soil). The case group experienced significantly higher levels of fatigue during high-intensity work (digging) than during the rest condition. These findings indicate that appropriate workload allocation, according to health, is necessary in the community garden setting because reducing the intensity of work assignments for people with mental disabilities will reduce their physical stress., MDPI AG
SUSTAINABILITY, Jan. 2017, [Reviewed] - Effect of added organic matter on soil fertility after stripping-off Cs-contaminated top soil at Iitate village in Fukushima Prefecture
Junko Nishiwaki; Naomi Asagi; Masakazu Komatsuzaki; Masaru Mizoguchi; Kosuke Noborio, The agricultural fields were contaminated by the radionuclides Cs-134 and Cs-137 after the nuclear power plant accident in Fukushima. Prior to the accident, local farmers had successfully established sustainable agriculture in Iitate Village using natural farming practices and recycling. Since 2011, decontamination work such as stripping-off the top soil has been ongoing on agricultural land. Although decontamination is essential, it could cause an unfortunate decrease in soil fertility. Here, we examined the use of organic matter as a means to quickly recover the fertility of the agricultural top soil. We transplanted rice crops into three paddy plots: one received rice straw that had been harvested there last year, another received composted manure, and the third (control) received no additives after decontamination. We applied 40 kg/10a of basal fertilizer and 20 kg/10a of KCl each plot. The rates of Cs concentration in unhulled rice/rice straw were around 0.001. Tendency of plant heights increase and leaf chlorophyll content decrease were similar in the three treatment plots. However, the numbers of stems on 111 days after the transplant were 21, 15, and 19, unhulled rice yield were 513, 462, and 310 g/m(2), in the rice straw, cattle manure compost, and control plots, respectively. Soil properties of three plots were similar. Radioactive Cs concentrations in the new rice from each treatment plots were lower than the maximum allowed level set by the Japanese government. These results revealed that treating soil with rice straw might have great potential to aid the recovery of a paddy field after stripping-off the top soil. Notably, this treatment significantly improved the yield of rice and supplied organic matter without additional labor., SPRINGER HEIDELBERG

Tropical Agriculture and Development, 2017, [Reviewed] - Contribution of N Derived from a Hairy Vetch Incorporated in the Previous Year to Tomato N Uptake under Hairy Vetch-tomato Rotational Cropping System.
Yuichi Sugihara; Hideto Ueno; Toshiyuki Hirata; Masakazu Komatsuzaki and Hajime Araki., Utilization of cover crops helps the establishment of environmentally friendly agriculture due to their nutrition supplying ability mainly in the current year of application, but cover crop-derived N also remains until the following year. In the present study, the nutritional effect of a cover crop on tomato production in a greenhouse in the following year was investigated using the N-15-labeling method. Hairy vetch (Vicia villosa R., HV) was used as a cover crop. N-15-labeled HV (1319 mg N/pot) was applied to a 1/2000 a Wagner pot, and a fresh market tomato (Solanum lycopersicum L.), 'House Momotaro' was cultivated in it at 0, 80, and 240 kg.ha(-1) of N application in 2011 (N0HV, N80HV, and N240HV). After the tomato cultivation in 2011, the soil was stored in a greenhouse (the temperature varied from -4.1 degrees C to 26.5 degrees C) without any water or fertilizer. Tomatoes were cultivated again in the Wagner pots containing the soil used in 2011, to which was added the same rate of N fertilizer (0, 80, and 240 kg.ha(-1) of N) and unlabeled HV (935 mg N/pot) in 2012. Total N uptake of tomato plants was higher in N240HV (2377 mg/plant), followed by N80HV (1760 mg/plant), N0HV (1498 mg/plant). On the other hand, the uptake of N derived from HV applied in 2011 (HV2011, 1319 mg N/pot) was not different among the treatments (57.7 mg/plant on average); thus, nitrogen use efficiency derived from HV2011 in 2012 was 4.4% on average. This value was much lower than that in 2011 (47.1% on average), but HV2011-N also remained in the soil after the tomato cultivation in 2012 (500 mg N/pot). The distribution ratios of HV2011-N to the fruit in 1st and 2nd fruit clusters that developed in the early growth period were higher than those of N derived from soil, fertilizer, and HV applied in 2012. These results showed that although the N supplying effect of HV was small, HV could be available not only as short-term N source, but also long-term N source, and HV-derived N applied in the previous year was absorbed by tomato plants during a relatively early growth period in the following year., JAPAN SOC HORTICULTURAL SCI
The Horticulture Journal, 2016, [Reviewed] - Characteristics of Elemental Composition and Organic Component of Indonesian Rice:Examples of Several Products in Indonesia Including Organic Rice
Nobuo SAKAGAMI; Fumitaka SHIOTSU; Nurwulan Agustiani; Masakazu KOMATSUZAKI and Youji NITTA,Recently, changes in dietary life and rising awareness of agricultural food safety and health driven by economic growth have enhanced popular interest in organic rice production in Indonesia. Farmers are also showing a growing interest in organic rice cultivation since it can be sold at higher prices. In meeting such new demands, knowledge of chemical properties of rice is beneficial as fundamental information. Therefore, palatability-related characteristics, vibrational spectra and contents of water, ash, total C, total N and metal elements of milled rice that is popular in Indonesia, adding milled Japonica rice as control, were investigated in this study. The palatability scores of Indica rice were generally low, but those of organic rice varieties were slightly higher than conventional rice. No definite difference for FT-IR spectra was found between Japonica rice and Indica rice. Regarding total nitrogen content, organic rice showed low values, presumably reflecting reduced nitrogen input because of the use of organic fertilizers. Japonica rice showed higher contents of magnesium, silicon, iron, and copper and lower contents of rubidium and molybdenum compared to Indonesian rice. Organic rice varieties showed clearly lower contents of iron and zinc. It seems clear that if conversion to organic farming proceeds, then it will alter the dynamics of inorganic nutrients as well. Future research undertaken to do detailed content analysis pertaining to quality and palatability of Indica rice is needed, taking note of different cultivation methods.

Journal of Environmental Radioactivity, 2015 - Effect of no-tillage with weed cover mulching versus conventional tillage on global warming potential and nitrate leaching.
Yagioka; A; M.Komatsuzaki; H.Ueno; and N.Kaneko, Abandoned agricultural land could potentially accumulate soil organic carbon (SOC) when it is no longer used for cultivation and is allowed to revert to natural vegetation. In Japan, no tillage with weed mulching will be adopted in marginal farmland as a new organic farming system because this system minimizes the disturbance of the soil ecosystem and reduces the cost for crop production. The present study aimed to compare the effects of two organic farming systems, namely no-tillage with weed cover mulching and conventional tillage (CT), and two organic fertilizer application modes, namely no fertilizer (N-) and organic fertilizer (N+; 50 kg N ha(-1) during 2010 and 2011 and 80 kg N ha(-1) during 2012) on greenhouse gas (GHG) fluxes, soil carbon sequestration, net global warming potential (GWP), and nitrate leaching. Pumpkin (Cucurbita spp.) was cultivated as the main crop in 2010 and 2011, whereas mixed cropping of okra (Abelmoschus esculentus L.), bell pepper (Capsicum annuum L.), and eggplant (Solanum melongena L.) was implemented in 2012. Tillage management increased CH4 uptake immediately after the tillage; however, the effects did not continue in the long term. On the contrary, NTW increased CH4 uptake, and the soil carbon content at the soil surface linearly increased every year after conversion to NTW indicating that improving soil physics by continuing NTW contributed to enhanced CH4 uptake. N2O emissions in NTW were higher only immediately after a weed mowing; however, NTW did not increase the annual N2O emission. In addition, the difference between initial and final SOC (Delta SOC) was greater in NTW than in CT, which significantly decreased net GWP in NTW in comparison with CT. Nitrate leaching was 48.6% and 47.3% lower in NTW than in CT at soil depths of 30-60 and 60-90 cm, respectively. These results show that no-tillage with weed cover mulching contributed to conserve the regional and global environment by reducing nitrate leaching and net GWP from the agro-ecosystem by increasing the annual CH4 uptake and soil carbon sequestration. This system will be adopted for abandoned agricultural land because it reduces net GWP shortly after conversion to this management. (C) 2014 Elsevier B.V. All rights reserved., ELSEVIER SCIENCE BV
Agriculture, Ecosystems and Environment, 2015 - Soil nematode community structure affected by tillage systems and cover crop managements in organic soybean production.
Ito; T.; M. Araki; M. Komatsuzaki; N. Kaneko; and H. Ohta, Information associating the tillage disturbance and its effect over soil nematode communities in different tillage systems has not been thoroughly discussed, especially in Asian countries. We investigated the effect of three tillage systems, i.e., moldboard plow/rotary harrow (MP), rotary cultivation (RC), and no-tillage (NT), and three cover crop treatments (fallow, rye, and hairy vetch) with two manure applications (0 and 1 Mg ha(-1)) on nematode communities and degree of surface soil translocation (DTL). This study was conducted in Japanese Kanto region (Andosols) in 2009-2011. We calculated nematode community indices, including channel index, enrichment index, and structure index (SI), based on the composition of nematode assemblages, to infer soil ecosystem condition. DTL was calculated from data on the variation of vertical soil distribution of radioactive cesium-137 deposited following the Fukushima Daiichi nuclear power plant accident in 2011. Tillage system influenced nematode abundance of all feeding groups. Cover crop also affected abundance of bacterial feeders (BAC), fungal feeders and facultative root feeders (FFR), predators (PRD), and obligatory root feeders (ORF). SI was bigger in NT, which was 22% and 47% higher than in MP and RC, respectively. DTL negatively correlated with abundance of BAC, omnivores, ORF, total number of nematode species, and SI, but positively correlated with the abundance ratio of FFR to FFR + BAC. Our results suggested that tillage inversion exerted stronger effects on nematode community and structure of soil ecosystem than cover crop treatment and manure application. (C) 2014 Elsevier B.V.

Applied Soil Ecology, 2015, [Reviewed] - Responses of soil nematode community structure to soil carbon changes due to different tillage and cover crop management practices over a nine-year period in Kanto
Ito; T.; M. Higashi; T.; Araki; M. Komatsuzaki; N. Kaneko; and H. Ohta, The response of the soil food web structure to soil quality changes during long-term anthropogenic disturbance due to farming practices has not been well studied. We evaluated the effects of three tillage systems: moldboard plow/rotary harrow (MP), rotary cultivator (RC), and no-tillage (NT), three winter cover-crop types (fallow, FL; rye, RY; and hairy vetch, HV), and two nitrogen fertilization rates (0 and 100 kg N ha(-1) for upland rice, and 0 and 20 kg N ha(-1) for soybean production) on changes in nematode community structure. Sixty-nine taxa were counted, total nematode abundance (ALL), bacterial feeders (BAC), predators (PRD), omnivores (OMN), and obligatory root feeders (ORF) were more abundant in NT than in MP and RC, but fungal feeders and facultative root feeders (FFR) were more abundant in RC than in NT and MP. Cover crop also influenced nematode community structure; rye and hairy vetch were always higher in ALL, BAC, FFR, ORF, and OMN than fallow. Seasonal changes in nematode community structure were also significant; in particular, as soil carbon increased, nematode abundance also increased. The relationship between nematode indices and soil carbon was significant only in NT, but not in MP and RC. In NT, with increasing soil carbon, enrichment index and structure index (SI) were positive and significant and channel index was negative. Bulk density was significantly negatively correlated with FFR and ORF. Seasonal difference in nematode community between summer and autumn was larger in an upland rice rotation than in a soybean rotation. Over the nine-year experiment, SI increased not only in NT but also in MP and RC, suggesting that repeated similar tillage inversions in agroecosystems may develop nematode community structures adapted to specific soil environmental conditions. Because NT showed the highest values of both SI and soil carbon, the increase of soil carbon in NT is expected to have a great impact on developing a more diverse nematode community structure.

Japan Applied Soil Ecology., 2015, [Reviewed] - Fate of 15N-labeled Inorganic Fertilizer in an Upland Soil Applied with Sweet Sorghum Bagasse and N Uptake Efficiency by Komatsuna Plants.
Naomi Asagi,Tatsuya Miya,Takashi Homma; Fumitaka Shiotsu; Toshiaki Kokubo; Youji Nitta; Hideto Ueno; Tatsuo Sato; Masakazu Komatsuzaki,and Akira Kato, Sweet sorghum bagasse (SSB) is a soil amendment with potential for biofuel production. This study was conducted to determine the appropriate techniques for application of SSB and the effect of incorporation of inorganic fertilizer (IF) on the production of komatuna (Brassica rapa) plants. SSB was applied to the surface of the plant or incorporated into soil. The N fate of IF was evaluated by using N-15-labeled IF. The combination of surface application of SSB and incorporation of IF to soil decreased the N uptake by komatsuna plants but increased dry weight, whereas the incorporation of IF and SSB gave lower komatsuna dry weight than IF treatment alone. Moreover, the application of SSB tended to increase the N distribution from IF to komatsuna with decreased N loss from the plant-soil system. These results showed that surface application of SSB is effective for increasing crop production due to reduction of N loss and improved N use efficiency., CROP SCIENCE SOC JAPAN

Winter annual grass cover crops can conserve residual soil N; however, their ability to recover N greatly varies with management. A two-year field experiment in the North Carolina Coastal Plain on a State fine sandy loam (fine-loamy, mixed, thermic Typic Hapludult) compared dry matter (DM), N accumulation, and soil inorganic N following rye (Secale cereale L.), winter wheat (Triticum aestivum L.), triticale (Triticum secale L.), black oats (Avena strigosa L.), and fallow (native weeds) in relation to planting (October, November, and December) and growth termination (early March, early April, and late April/early May) dates and levels of residual soil N. Cover crop DM and N accumulations decreased with successive planting date delays (November and December) for each growth termination date in the following spring. In 2000, cumulative DM yields of October-and November-planted cover crops were 3.17 Mg ha(-1) (1.41 tn ac(-1)) and 3.74 Mg ha(-1) (1.66 tn ac(-1)), respectively, which were significantly greater than those of December-planted cover crops (1.90 Mg ha(-1) [0.84 tn ac(-1)]) at the second growth termination date (early April). Cover crop N accumulation increased with a delay in growth termination, although the interaction between cover crop species and the planting date varied. October planting of rye and triticale showed greater N accumulation at a March growth termination date, averaging 37.8 kg N ha(-1) (33.7 lb N ac(-1)) for rye and 37.6 kg N ha(-1) (33.5 lb N ac(-1)) for triticale; these values were 7.8% and 14.1% higher than those of black oat and wheat, respectively, at the same planting and growth termination dates. November-planted wheat showed in the highest N accumulation (average, 57.9 kg N ha(-1) [51.7 lb N ac(-1)]) at the late April/early May termination date; this was 3.8% to 7.9% higher than that of other species. In contrast, black oat showed a greater ability to scavenge soil residual N with a late planting and growth termination date combination (average, 58.7 kg N ha(-1) [52.4 lb N ac(-1)]). The cover crop planting date affected soil inorganic N distribution at each termination date, with an October planting date resulting in lower soil profile inorganic N levels than November and December planting dates. Lower soil inorganic N concentrations were strongly associated with increases in cover crop DM and N accumulation for each growth termination date. These results should help growers identify the best niche for a cover crop with respect to recovering residual soil N in their various rotations., SOIL WATER CONSERVATION SOC
Journal of Soil and Water Conservation, 2015, [Reviewed] - No-tillage cultivation reduces rice cyst nematode (Heterodera elachista) in continuous upland rice (Oryza sativa) culture and after conversion to soybean (Glycine max) in Kanto Japan.
Ito; T.; M. Araki; M. Komatsuzaki, The rice cyst nematode, Heterodera elachista, previously reported only in Japan, has recently been detected elsewhere in Asia and in Europe. Because control of H. elachista by fumigation is economically impractical, control through farming practices in the form of tillage, cover cropping, and N fertilization is needed. We evaluated the effects of three tillage systems (moldboard plow [MP] with rotary cultivation, rotary cultivator [RC], and no-tillage [NT], three winter alternatives (fallow; rye or hairy vetch cover crops), and two rates of N fertilization (0 and 100 kg ha(-1) on upland rice and 0 and 20 kg ha(-1) on soybean) on population densities of H. elachista in 2003 to 2011. During the first 3 years of continuous upland rice cropping, population densities were very low. By 4 years (2006), they increased markedly in MP and RC (216.0 and 282.8 nematodes, respectively, per 100g dry soil) but not in NT (111.1 per 100g). However, by 5 years, they increased markedly in NT too, eliminating any differences between tillage systems. After conversion to soybean, H. elachista densities decreased in all treatments, but decreased fastest in NT. Cover cropping and N fertilization did not markedly affect H. elachista densities, but cover cropping reduced the proportion of H. elachista among all nematodes in one year, and N fertilization increased the degree of rice yield reduction by increasing H. elachista abundance by the 5th year. Our results suggest that NT and crop rotation can help in controlling H. elachista densities. (C) 2015 Elsevier B.V. All rights reserved., ELSEVIER SCIENCE BV
Field crop research, 2015, [Reviewed] - Initiation and Dissemination of Organic Rice Cultivation in Bali, Indonesia.
Shiotsu; F.; Sakagami; N.; Asagi; N.; Suprapta; D.N.; Agustiani; N.; Nitta; Y.; Komatsuzaki; M., Organic farming has attracted attention in Indonesia because consumers increasingly prefer the putative safety and health benefits of organic farm products. Although national standards for organic farm products were established in 2002, some products sold as organic products in supermarkets do not carry the certification mark. This study investigated organic rice farming on the island of Bali in Indonesia using fieldwork to ascertain the actual increase in organic farming. Results revealed that government certified organic farming used originally produced cattle manure to grow organic rice. At the market, however, some quasi-organic farming products, which had not been given the organic farming certification, were sold as organic rice. This eventuality suggests that although organic farming has been increasing steadily in Bali, development of sustainable recycling agriculture demands technical guidance and increased publicity for organic farming, based on national certification, to address misunderstandings and confusion about the definitions of organic farming and national standards that are transparent to producers and consumers., MDPI AG
Sustainability, 2015, [Reviewed] - Tillage can reduce the radiocesium contamination of soybean after the Fukushima Dai-ichi nuclear power plant accident.
Hoshino; Y.; Higashi; T.; Ito; T.; and Komatuzaki; M., A magnitude 9.0 earthquake and a subsequent large tsunami hit the northeastern coast of Japan on March 11, 2011. This resulted in serious damage to the reactors of the Fukushima Dai-ichi nuclear power plant (FDNPP), operated by the Tokyo Electric Power Company. Large amounts of radionuclides were released from the FDNPP, a proportion of which were deposited on the ground. In this study, we investigated soil radiocesium contamination of soybean fields in Ibaraki, approximately 170 km from the FDNPP. After the accident, we compared the radiocesium contamination in soybeans cultivated using different tillage systems and cover crop species. The different tillage systems were moldboard plow/rotary harrow (MP), rotary cultivation (RC), and no tillage (NT); the three types of winter cover crops were fallow weeds, rye, and hairy vetch; and for soybean production we used two rates of manure (0 and 1 Mg ha(-1)). MP and RC reduced the radiocesium contamination (C-134(S) + C-137(S)) in the 0-2.5 cm soil layer (509.7 Bq kg(-1) for MP and 782.7 Bq kg(-1) for RC), although NT left a large amount of radiocesium on the soil surface (1324.8 Bq kg(-1)). The radiocesium concentration of the rye cover crop was significantly lower than hairy vetch and fallow during 3 years. In 2013, across the tillage system, radiocesium concentration of rye was ;only 3.4 Bq kg(-1), although those values were 17.7 Bq kg(-1) for hairy vetch and 56.4 Bq kg(-1), for fallow. The radiocesium concentration in soybean grains was significantly lower in MP and RC than in NT from 2011 to 2013. In 2013,3 years after the FDNPP accident, the radiocesium concentration of soybean grain was 14.8 Bq kg(-1) for NT, although these values were 5.8 Bq kg(-1) for MP and 6.5 Bq kg(-1), for RC. The transfer factor for soybean grain was significantly lower in MP and RC than in NT, although the transfer factor in NT also decreased each sampling year from 0.12 to 0.08 after the FDNPP accident. We conclude that despite numerous benefits of the NT system for environmental conservation, soil inversion by tillage significantly decreased the radiocesium contamination of crops. Thus, tillage inversion would be appropriate to counter measures after the nuclear accident. (C) 2015 Elsevier B.V. All rights reserved., ELSEVIER SCIENCE BV

Sustainability (United States), 2015, [Reviewed] - The effect of minimum tillage with weed cover mulching on organic daikon (Raphanus sativus var. longipinnatus cv. Taibyousoufutori) yield and quality and on soil carbon and nitrogen dynamics
Atsushi Yagioka; Masakazu Komatsuzaki; Nobuhiro Kaneko, Minimum tillage with weed cover mulching (MT) could be one alternative practice for root vegetable production because of soil erosion control and energy savings. This study compared the effects of MT and conventional tillage with weed removal (CT) on daikon yield and quality, soil carbon and nitrogen dynamics, and physical properties under organic farming practices. Root yields of daikon were 77% higher on average in MT than in CT although weed biomass was higher in MT than in CT in both years. Organic fertilizer application also significantly increased daikon yield. Nitrate-N content in daikon root was lower in MT than in CT. Soil total C and N at 0-2.5cm soil depth were significantly higher in MT than in CT in both years but organic fertilizer application did not increase soil total C and N. Soil bulk density at 0-7.5cm soil depth was significantly lower in MT than in CT. Penetration resistance between daikon rows was also significantly lower in MT than in CT at 0-4cm soil depth, although this relationship was reversed in between 11 and 17cm soil depth. These results suggest that MT is a beneficial approach for root vegetable production, given that it produces excellent crop yields and increased soil total C and N with minimum disturbance to agro-ecosystems., TAYLOR & FRANCIS LTD

有機農業研究, 2014 - Tillage and cover crop species affect soil organic carbon inAndosol,Kanto,Japan.
Higashi; T.; Y.Mu; M.Komatsuzaki; S.Miura; S.Hirata; H.Araki; N.Kaneko; H.Ohta, No-tillage, cover crops, and N fertilization play important roles in conserving or increasing soil organic carbon (SOC). However, the effects of their interaction are less well known, particularly in Asian countries. We examined the effects of three tillage management systems, moldboard plow/rotary harrow (MP), rotary cultivator (RC), and no-tillage (NT); three winter cover crop types (FL: fallow, RY: rye, and HV hairy vetch); and two nitrogen fertilization rates (0 and 100 kg N ha(-1) for upland rice and 0 and 20 kg N ha(-1) for soybean production) on changes in SOC. Vertical distributions at 0-2.5, 2.5-7.5, 7.5-15, and 15-30 cm depths of soil carbon content and bulk density were measured each year. From 2003 to 2011, NT and RC management increased SOC by 10.2 and 9.0 Mg ha(-1), whereas SOC under the MP system increased only by 6.4 Mg ha(-1). Cover crop species also significantly increased SOC in the same period by 13.4 and 8.6 Mg ha(-1) for rye and hairy vetch, respectively, although SOC with fallow increased only by 5.4 Mg ha(-1). Continuous soil management for 9 years enhanced SOC accumulation. Summer crop species between upland rice and soybean strongly affected SOC; the SOC increases were 0.29 Mg ha(-1) year(-1) for the upland rice rotation and 1.84 Mg ha(-1) year for the soybean rotation. However, N fertilization levels did not significantly affect SOC. These results suggest that the NT system and rye cover crop enhance carbon sequestration in Kanto, Japan, but that their contributions differ depending on the combination of main and cover crops.

Soil&Tillage Research, 2014 - A New Strategy for Utilizing Rice Forage Production Using a No-Tillage System to Enhance the Self-Sufficient Feed Ratio of Small Scale Dairy Farming in Japan.
Windi Al Zahra; T. Yasue; N. Asagi; Y. Miyaguchi; B. P. Purwanto and M. Komatsuzaki, Rice forage systems can increase the land use efficiency in paddy fields, improve the self-sufficient feed ratio, and provide environmental benefits for agro-ecosystems. This system often decreased economic benefits compared with those through imported commercial forage feed, particularly in Japan. We observed the productivities of winter forage after rice harvest between conventional tillage (CT) and no-tillage (NT) in a field experiment. An on-farm evaluation was performed to determine the self-sufficient ratio of feed and forage production costs based on farm evaluation of the dairy farmer and the rice grower, who adopted a rice forage system. The field experiment detected no significant difference in forage production and quality between CT and NT after rice harvest. However, the production cost was dramatically decreased by 28.1% in NT compared with CT. The self-sufficient ratio was 5.4% higher when dairy farmers adopted the rice forage system compared with those using the current management system. Therefore, this study demonstrated the positive benefits for dairy farmers and rice growers in Japan when adopting a rice forage system with NT, which could improve the self-sufficient feed ratio and reduce production costs., MDPI AG

Kanto Journal of Crop Science, 06 Dec. 2013 - APPLICATION OF PORTABLE HYPER-SPECTRAL CAMERA IN ANDISOLS SOIL NITROGEN ASSESSMENT
Tiejun Zhao; Kenshi Sakai; Tatsuya Higashi; Masakazu Komatsuzaki; Xujun Ye, Soil nitrogen content has very important influence on soil parameters and crop productions, so the soil nitrogen monitoring and management are urgently required to satisfy the demand for precision agriculture. This research is aimed to develop the simple and low cost monitoring methods to determine the soil nitrogen pools using hyper spectral camera in Andisols soil. Partial least square regression (PLSR) with cross-validation was used to calibrate the spectral data. The research estimated the potential of soil nitrogen qualitative analysis using visible (VIS) spectrographs, near infrared (NIR) spectrographs and combination of these two spectrographs. Results showed that model assessment accuracy by V10 (360nm-1010nm) spectrograph is higher than by N17E (900nm-1700nm) spectrograph. In addition, combining these two spectrographs increased the model prediction accuracy. Evaluation index (EI) test was employed in this research, and the results showed that prediction is acceptable to use of practical to predict soil nitrogen content., IEEE

Soil and Tillage Research, 2013 - Performance of no-tillage seeder under different cover crop species and residue managements for sweet sorghum in sustainable biofuel production.
Zhao; T.; Zhao; Y.; Nitta; Y.; Yagioka; A.; Komatsuzaki; M., The strategy for sustainable biofuel production should be compatible with increasing SOM (soil organic matter) to improve soil quality for biomass productivity and reducing purchased inputs for production. Combining cover crops with no-tillage offers many benefits for improving soil quality, but requires a higher level of management to achieve maximum benefit. This study evaluated the performance of a no-tillage seeder for sweet sorghum production and identified appropriate ways of using the no-tillage seeder with various amounts of cover crop residue. Previous field researchrevealed that using a medium (360 rpm) PTO rotational speed and mixed-seeding of rye and hairy vetch with a no-tillage seeder is effective for increasing sweet sorghum germination undercover crop residue mulch., Elsevier B.V.

高橋正通; 小松崎将一; 長谷川元洋; 橋本みのり; 金子信博, Natural forest soils promote sustainable production of the plant community by recycling ecosystem nutrients. To understand the nutritional characteristics of forest soils as a reference for conservation agriculture, which aims at reducing the use of fertilizer and enhancing biodiversity, we studied moderately moist Brown Forest Soils and Black soils on the footslopes of forested hills. We applied the criteria for desirable soil properties for crop and orchard lands as promoted by the Ministry of Agriculture, Forestry and Fisheries of Japan. Contents of organic matter and available nitrogen in the forest soils were 2 to 3 times those in agricultural soils. However, the pH in the forest soils was low, at about 5, and the concentration of exchangeable cations was also low, at around 10 cmolc kg-1. To understand how the nutrient characteristics of the forest soils form, we compared aspects of agricultural management, for example, the application of compost and lime, with the amount of litterfall and nutrients in the O layer. The productivity of the forest soil seems to be maintained by a lack of disturbance, which favors the predominance of the fungal community in the acidic soil in the absence of fertilizer use, the formation of soil aggregates by soil macrofauna, and the accumulation of nutrients in tree organs. To enable sustainable soil management on agricultural land with reduced fertilizer use, we will need to replicate the overall biological functions seen in the forest soils., Japanese Society of Soil Science and Plant Nutrition
日本土壌肥料学会誌, 2013 - Effects of tillage and winter cover cropping on microbial substrate-induced respiration and soil aggregation in two Japanese fields.
Nakamoto; T.; Komatsuzaki; M.; Hirata; T.; Araki; H., We hypothesized that cover cropping could increase soil microbial activities under various tillage systems and that increased microbial activities would improve soil properties. Soil sampling was conducted at two fields in Japan in 2009. At the Ibaraki field (Andosol, clay loam), three, tillage practices (no-tillage, plowing to 30 cm, and rotary tillage to 15 cm) and three types of winter cover cropping [bare fallow as control, hairy vetch (Vicia villosa Roth), and rye (Secale cereale L.)] were conducted from 2003 to 2009. At the Hokkaido field (Fluvisol, light clay), two tillage practices (autumn tillage and rotary tillage with a rotary tiller to a depth of 15 cm once in autumn and twice in a year, respectively), and four types of winter cover cropping (bare fallow, hairy vetch, bristle oat (Avena strigosa L.), and a mixture of hairy vetch and bristle oat) were conducted from 2006 to 2009. Soil microbial activities and the fungal-to-bacterial activity ratio (FIB ratio) were estimated by the substrate-induced respiration (SIR) method with the use of selective antibiotics. At the Ibaraki field, rye cover cropping showed higher microbial SIR than bare fallow at depths of 0-30 cm and rotary tillage maintained higher microbial SIR than no-tillage or plowing at depths of 7.5-1.5 cm. There was no meaningful interaction effect between cover cropping and tillage on microbial SIR. At the Hokkaido field, cover cropping and tillage had only limited effects on microbial SIR. High FIB ratios (indicating fungal dominance) were recorded with the use of cover crops in both fields. Fungal SIR, estimated from the microbial SIR and FIB ratio, was closely related to the content of total soil organic carbon (SOC) and the mean weight diameter (MWD) of water-stable aggregates. Based on SOC, fungal SIR was significantly higher under rye cover cropping. The relationship between fungal SIR and MWD was affected by tillage. We conclude that rye cover cropping and rotary tillage were very effective in increasing fungal SIR, SOC, and MWD in the Ibaraki soil. Field practices that enhance fungal activities might be effective in improving certain types of arable soil., TAYLOR & FRANCIS LTD
Soil Science and Plant Nutrition, 2012 - Power consumption of no-tillage seeder under different cover crop species and termination for soybean production.
Zhao; T.; Zhao; Y.; Higashi; T.; Komastuzaki; M., To achieve the maximum benefit of no-tillage with cover crop in the sustainable farming system, we conducted experiments on the performance and power consumption of a no-tillage seeder under different combinations of cover crop species, residue management and termination in soybean production. The results showed that the power consumption of the no-tillage seeder was higher with rye than hairy vetch and mixed-seeding, and increased with higher quantity of cover crop residue. The termination and management of cover crop significantly affected the cover crop biomass accumulation and power consumption of the no-tillage seeder. The results revealed that late cover crop termination increases the biomass while the performance of the no-tillage seeder declined. Therefore, flail mower cutting and mix seeding were appropriate for improving the no-tillage seeder in soybean production., Elsevier B.V.

International Research Journal of Agricultural Science and Soil Science, 2012 - How different or similar are nematode communities between a paddy and an upland rice fields across a flooding-drainage cycle?
Hiroaki Okada; Shigeru Niwa; Shuhei Takemoto; Masakazu Komatsuzaki; Mikiya Hiroki, The paddy field is being recognised as a biodiversity hotspot fostering a variety of organisms. However, there are few studies on the ecology of paddy field nematodes. We characterised nematode communities in rice paddy fields by comparing them with upland fields of rice or soybean. We examined nematode communities of the top (0-15 mm) and second (15-50 mm) soil layers before flooding (March or April), during flooding (June or July) and during the draining period (October) 2007-2009. We found that the nematode community in the paddy was different than that in the upland fields during all periods. Rhabdolaimus, Tobrilus, Mesodorylaims and Monhysteridae characterised the top of the paddy and Hirschmanniella characterised the second layer of the paddy. Total nematode density was generally lower in the paddy than in the upland field. However, the density in the paddy top layer increased with time from the flooding period to the draining period, during which time it was about the same as (or even greater than) the peak density in the upland fields. The density in the second layer of the paddy remained lower than that in the top layer of the paddy throughout the time course. Community diversity values were generally greater in the paddy top layer than in the paddy second layer across the six sampling periods, but periodic differences between the paddy and upland fields or between soil layers were not significant. During the flooding period, the F/(F + B) (13-37) and Enrichment Index (17-38) values were lower in the paddy than in the upland fields (32-47, 37-74, respectively) to reflect that bacteria dominate over fungi with slow decomposition due to anaerobic conditions in the flooded paddy field. In addition, particularly in the top layer, the Maturity (2.0-2.4) and Structure Index (23-72) values were greater in the paddy than in the upland fields (1.7-2.1, 9-15, respectively), indicating a well-developed ecosystem under water. These unique nematode communities persisted during the draining period, but there was a rapid increase in opportunistic bacterivores, which increased the El values. We suggest that bactivorous nematodes in the families Cephalobidae and Chronogasteridae, herbivores in the genus Hirschmanniella, and fungivores in the genus Filenchus may be specific to paddy field soil rather than to pond and lake sediments.

土と微生物, 2011 - Comparison of the farming system and carbon sequestration between conventional and organic rice production in West Java, Indonesia
Masakazu Komatsuzaki; M. Faiz Syuaib, Organic farming provides many benefits in Indonesia: it can improve soil quality, food quality and soil carbon sequestration. This study was designed to compare soil carbon sequestration levels between conventional and organic rice farming fields in west Java, Indonesia. The results from soil analysis indicate that organic farming leads to soil with significantly higher soil carbon storage capacity than conventional farming. Organic farming can also cut some farming costs, but it requires about twice as much labor. The sharecropping system of rice farming in Indonesia is highly exploitative of workers
therefore, research should be conducted to develop a fairer organic farming system that can enhance both local and global sustainability. © 2010 by the authors

This axenic strain formal colonies and was motile on an agarose plate. The 16S rRNA gene of ABRG5-3 exhibited similarities to those of the Limnothrix and Pseudanabaena strains, which are known as filamentous and nonheterocystous cyanobacteria. Peaks in absorbance for the accumulation of chlorophyll a, phycocyanin, and phycoerythrin were observed in the cell extract. Natural separation of the pigments occurred in the supernatant of the autolysed cells. The cell lysis was promoted by osmotic shocks and lysozyme treatments. Chlorophyll a and total DNA were abundantly recovered from the cells. Analysis of the restriction-modification system for genomic DNA revealed novel diversity. Moreover, we made a successful attempt to create antibiotic-resistant strains by conjugation with a foreign plasmid, which indicates that strain ABRG5-3 is transformable., TAYLOR & FRANCIS LTD

Tiejun Zhao; Masakazu Komatsuzaki; Hiroshi Okamoto; Kenshi Sakai, This study evaluated the potential of portable spectral camera techniques for measuring cover crop chemical composition in different growth stages. A height measurement system was also developed using a laser distance sensor to predict cover crop biomass. PLS (Partial Least Squares) regression was used to evaluate the relationship between cover crop nutrient content and spectral data. The study revealed that a partial cross-sectional area of canopy had a slightly higher correlation with the cover crop biomass than that of the canopy height. High correlations were observed between the predicted and observed accumulation of N (R2 = 0.8698), Ca (R2 = 0.8512), Mg (R2 = 0.8415) and K (R2 = 0.9451).

Tomoyasu Nishizawa; Zhaorigetu; Masakazu Komatsuzaki; Yoshinori sato; Nobuhiro Kaneko; Hiroyuki Ohta, This study aimed to characterize soil fungal communities in upland rice fields managed with tillage/non-tillage and winter cover-cropping (hairy vetch and cereal rye) practices, using PCR-based molecular methods. The study plots were maintained as upland fields for 5 years and the soils sampled in the second and fifth years were analyzed using T-RFLP (terminal restriction fragment length polymorphism) profiling and clone libraries with the internal transcribed spacer (ITS) region and domain 1 (D1) of the fungal large-subunit (fLSU) rRNA (D1(fLSU)) as the target DNA sequence. From the 2nd-year-sample, 372 cloned sequences of fungal ITS-D1(fLSU) were obtained and clustered into 80 non-redundant fungal OTUs (operational taxonomic units) in 4 fungal phyla. The T-RFLP profiling was performed with the 2nd- and 5th-year-samples and the major T-RFs (terminal restriction fragments) were identified using a theoretical fragment analysis of the ITS-D1(fLSU) clones. These molecular analyses showed that the fungal community was influenced more strongly by the cover-cropping than tillage practices. Moreover, the non-tilled, cover-cropped soil was characterized by a predominance of Cryptococcus sp. in the phylum Basidiomycota. We provided a genetic database of the fungal ITS-D1(fLSU)s in the differently managed soils of upland rice fields., JAPANESE SOC MICROBIAL ECOLOGY, DEPT BIORESOURCE SCIENCE

Journal of the Japanese Society of Agricultural Machinery, 2008, [Reviewed] - Relationships between Fungal Biomass and Nitrous Oxide Emission in Upland Rice Soils under No Tillage and Cover Cropping Systems
Zhaorigetu; Masakazu Komatsuzaki; Yoshinori Sato and Hiroyuki Ohta, The relationships between soil microbial properties and nitrous oxide emission were examined in upland Soil under different tillage systems [no tillage (NT), rotary and plow tillage] and cover crop systems (fallow, cereal rye, and hairy vetch) in 2004 and 2005. Microbiological analyses included the determination of soil ergosterol as all indicator of fungal biomass, bacterial plate counting, and MPN estimations of ammonia oxidizers and denitrifiers. The combined practice of NT with rye-cover crop treatment increased fungal biomass but not bacterial populations in 0-10 cm deep soils. Such increase in fungal biomass was not found in 10-20 cm and 20-30 cm deep cover-cropped NT soil. The combined practice of NT with rye-cover cropping resulted in higher in situ N(2)O emission rates compared with rotary- and plow-till treatments. N(2)O flux was positively correlated with soil ergosterol content but not with denitrifier MPN and other soil chemical properties. These results suggested a significant contribution of fungi to N(2)O emission in cover-cropped NT soils., JAPANESE SOC MICROBIAL ECOLOGY, DEPT BIORESOURCE SCIENCE

Microbes and Environments, 2008 - 14C ages and δ13C of sclerotium grains found in forest soils
Watanabe; M.; H. Sato; H. Matsuzaki; T. Kobayashi; N. Sakagami; Y. Maejima; H. Ohta; N. Fujitake; S. Hiradate, C-14 ages and delta C-13 were examined for sclerotium grains to elucidate the characteristics of these grains distributed in forest soils. The ages of the grains from surface A horizons and buried A horizons were ca 100-200 BP and ca 300-1,200 BP, respectively. In comparison with humic acid extracts, the C-14 ages were in the increasing order: humic acid fraction < humic acid Pg fraction < sclerotium grains. The delta C-13 values for sclerotium grains in surface A horizons and buried A horizons were approximately -31 parts per thousand to -28 parts per thousand, and these values were approximately 2-4 parts per thousand smaller than those of humic acids and soils. The C content of the grains had a tendency to decrease with increasing C-14 ages, while the C content of humic acid was constant with age. The C-14 ages of sclerotium grains indicate the individual age of grain formation, which are more likely to assign closer ages to the beginning of soil forming than the C-14 ages of humic acid. The low delta C-13 values for sclerotium grains have presumably originated from characteristically biological organics, which may be protected from attack in soils because of their structure., TAYLOR & FRANCIS LTD

牟英輝; 小松崎将一; 森泉昭治; 辜松; 荒木肇; 平田聡之, We investigated the changes in soil physical properties, such as soil cone index (SCI), soil bulk density (SBD) and soil water content (SWC) in upland rice (Oryza sativa L.) production following rye (Secale cereale L.), hairy vetch (Vicia villosa Roth) and fallow (no cover crop) under different tillage systems (plowing, rotary and minimum tillage) with 4 replications. Field experiments were conducted at the Experimental Farm of Ibaraki University on a Humic Allophane soil (Haplic Andsolos) from Aug. 2002 to Dec. 2004. The main results obtained from these 2 years of field research were as follows:
1) The tillage system significantly affected soil water content, with minimum tillage having the greatest effect. Cover crop types also showed significant effects on soil water content, especially for minimum tillage with rye treatment.
2) The tillage system also had a significant effect on soil bulk density, with minimum tillage having the greatest compare with other tillage treatment. Cover crop types, however, showed little effect on soil bulk density.
3) The tillage system also affected soil hard-ness significantly during the dry paddy rice growing season. SCI was the highest for no. -till treatment, and the lowest for plow tillage treatment. With all the tillage systems, cover crop types also showed significant effects on reducing SCI. SCI showed the lowest value for rye and the highest for fallow.
4) These results suggest that cover cropping has some potential for reducing soil hardness without tillage treatment; consequently, cover crops may be effective tools to optimize soil hard-ness in minimum tillage systems., Japanese Society of Farm Work Research
農作業研究, 2007 - New weed management strategy using subterranean clover reseeding under different tillage systems: Numerical experiments with the subterranean clover-tillage dynamics model
Komatsuzaki; M, Subterranean clover (Trifiolium subterraneum L.) appears to be a suitable winter legume cover crop for Japan because the subterranean clover stands maintain themselves by reseeding in autumn and the large seeds facilitate establishment and enable early fall production. However, there is little information on the relationship between reseeding and tillage systems for subterranean clover under Japanese climatic conditions. A weed-tillage population dynamics model was developed to investigate the effects of the tillage method and tuning on the reseeding of subterranean clover. The field experiments were conducted in a silage corn and subterranean clover rotation system. The life cycle of subterranean clover was modeled to describe the seed production competing with weed growth, seasonal changes in the buried seeds' viability, and the movement of seeds by tillage treatments. In the numerical simulation, the effect of the tillage method on the seedling population of reseeded subterranean clover was investigated and the simulation results showed good agreement with the experimental results. Rotary tilling inunediately after subterranean clover seed maturation successfully produced a good subterranean clover stand the following spring. However, rotary tillage conducted 2 months after seed maturation killed the emerging subterranean clover seedlings and the field was dominated by winter weeds. These simulation results suggest that a suitable tillage system can maintain successful subterranean clover re-establishment from year to year., BLACKWELL PUBLISHING
Weed Biology and Management, 2007, [Reviewed] - Soil management practices for sustainable agro-ecosystems
Komatuszaki; M. and H. Ohta, A doubling of the global food demand projected for the next 50 years poses a huge challenge for the sustainability of both food production and global and local environments. Today's agricultural technologies may be increasing productivity to meet world food demand, but they may also be threatening agricultural ecosystems. For the global environment, agricultural systems provide both sources and sinks of greenhouse gases (GHGs), which include carbon dioxide (CO(2)), methane (CH(4)), and nitrous oxide (N(2)O). This paper addresses the importance of soil organic carbon (SOC) for agro-ecosystems and GHG uptake and emission in agriculture, especially SOC changes associated with soil management. Soil management strategies have great potential to contribute to carbon sequestration, since the carbon sink capacity of the world's agricultural and degraded soil is 50-66% of the historic carbon loss of 42-72 Pg (1 Pg=10(15) g), although the actual carbon storage in cultivated soil may be smaller if climate changes lead to increasing mineralization. The importance of SOC in agricultural soil is, however, not controversial, as SOC helps to sustain soil fertility and conserve soil and water quality, and organic carbon compounds play a variety of roles in the nutrient, water, and biological cycles. No-tillage practices, cover crop management, and manure application are recommended to enhance SOC storage and to contribute to sustainable food production, which also improves soil quality. SOC sequestration could be increased at the expense of increasing the amount of non-CO(2) GHG emissions; however, soil testing, synchronized fertilization techniques, and optimum water control for flooding paddy fields, among other things, can reduce these emissions. Since increasing SOC may also be able to mitigate some local environmental problems, it will be necessary to have integrated soil management practices that are compatible with increasing SOM management and controlling soil residual nutrients. Cover crops would be a critical tool for sustainable soil management because they can scavenge soil residual nitrogen and their ecological functions can be utilized to establish an optimal nitrogen cycle. In addition to developing soil management strategies for sustainable agro-ecosystems, some political and social approaches will be needed, based on a common understanding that soil and agro-ecosystems are essential for a sustainable society., SPRINGER TOKYO

小松崎将一; 村中健一, Organic broccoli was grown in the fall of 2001 and 2002 at the Experimental Farm, Ibaraki University. The objective was to determine the yield responses, food qualities, and weeds suppression in a no-till production system in which mulch treatments included cover crops of forage soybean and Japanese millet as compared with the conventional cultivation production system. Two different killing cover crop methods that were the use of bush cutter and hammer knife mower, were applied to all mulch treatments.
Millet cover crop biomass showed the highest value that the ranged from 580kg/10a to 636kg/10a. Soybean N contents showed the highest value that the ranged 2.8kgN/10a to 6.3kgN/10a. Yields and head mass increased for millet mulch at an early harvest stage in both years. However, total yields were no significant differences between cover crop mulches and the conventional cultivation system. Broccoli sugar contents for millet mulch showed higher values compare with other treatment, and nitrate contents usually showed the lowest value. On the other hands, broccoli nitrate content for soybean mulch usually showed higher values comparewith other treatment. These results suggest that millet mulch would be an appropriate technique for organic broccoli production system because that would provide adequate soil nutrient condition., Japanese Society of Farm Work Research

辜松; 小松崎将一; 森泉昭治; 牟英輝, Winter cover crops can conserve soil residual nitrogen to prevent nitrogen leaching after summer crop harvest, and increase soil organic matter. However, grass and legume cover crops may have different abilities to conserve soil residual nitrogen. Field research was conducted for 2 year to investigate dry matter (DM) and nitrogen accumulation of crimson clover and rye cover crops at two soil nitrogen level in the relation to soil inorganic nitrogen distribution. The main results are as follows.
1) DM accumulation of rye was significantly higher than that of crimson clover and fallow (weeds) from Dec. to April. During the study period, the average DM of rye in April was 148.4% and 440.4% higher than that of crimson clover and fallow, respectively.
2) Cover crop nitrogen accumulation was associated with DM accumulation during their respective growing seasons. Cover crop nitrogen accumulation in April was the highest in rye (120.3kg ha-1), followed by crimson clover (69.2kg ha-1), and fallow (39.9kg ha-1).
3) Decrease of soil inorganic nitrogen was significant associated with cover crop DM and nitrogen accumulation in December, March and April.
4) This study showed that rye planted as a cover crop in fall can successfully prevent N leaching that is a potential source of groundwater contaminate. However, additional research would be needed to evaluate crimson clover can prevent N leaching., Japanese Society of Farm Work Research

辜松; 小松崎将一; 太田寛行; 本林 隆; 森泉昭治; 山口昌良, We investigated the changes of soil carbon content and the population of soil microorganisms, soil nematodes and soil animals in upland rice (Oryza. sativa L.) production following rye (Secale creale L.), crimson clover (Trifolium incamatum L.) and fallow (no cover) under different tillage systems (plow, rotary, and no-till) with 3 replications. The main results obtained for a 2 years field research were as follows.
No-till treatment enhanced soil respiration from 1 month after rice planting to July compared with plow and rotary plots. In 2001, the rye cover crop plot showed the highest soil respiration values for all tillage treatments, followed by crimson clover, and fallow treatment showed the lowest values for all tillage treatments.
Higher soil carbon content was observed in rye and crimson clover plots compared with the fallow plot in April, and this difference disappeared in May. However, that was also higher in the rye and crimson clover plots in September.
The population of soil microorganisms was strongly affected by tillage treatment, with the plow treatment having the lowest in most seasons. In all tillage and cover crop treatments, the population of soil animals was higher in May than in September, but no significant differences were observed among tillage and cover crop treatments.
The population of nematodes was strongly affected by cover crop and tillage treatments. For cover crop treatment, the population was higher in the rye and crimson clover plots than in the fallow plot, and for tillage treatment, the order was no-till>rotary>plow.
Cover crop treatments enhanced the soil respiration, the water holding capacity, soil carbon content and the population of nematodes. These results will be useful for enhancing the biological diversity of community in soils which is important for maintaining a healthy environment for plants., Japanese Society of Farm Work Research

American society of agronomy 96th annual meeting, 2004 - New Cropping Strategy to Reduce Chemical Fertilizer Application to Silage Corn Production Using Subterreanean Clover Reseeding.
Komatsuzaki; M., This study was conducted to evaluate the effects of reseeding sub clover as a cover crop on silage corn growth, nitrogen accumulation, and the changes in soil nitrogen under different chemical nitrogen application levels. The cropping systems of sub clover reseeding based management and fallow treatment were compared to DM and N accumulation of silage corn at 0, 50, and 100kg N ha-1 application levels. The experiment was conducted at two sites, one where no-till corn was sown in June, and the other where conventional corn was sown in July. DM accumulation of corn in the fields of sub clover reseeding system was significantly higher than in the fields of fallow system at both sites. Based on this co-relationship, the amounts of nitrogen supplied by sub clover reseeding to no-till and conventional tilled corn estimated to be 108 and 88kg N ha-1, respectively. However, the evaluation of sub clover N supply in this experiment was obviously influenced by sub clover N that was also produced other years were obvious. So these results also suggested that there is some possibility to increase the soil total nitrogen in the field of sub clover reseeding system. However, the amount of sub clover N supply per year is still not clear, so additional research is needed., Japanese Society of Farm Work Research

Japanese Journal of Farm Work Research, 1996 - Seed Longevity and Emergence of Volunteer Wheat in Upland Fields
Komatsuzaki Masakazu; Endo Oritaro, Since volunteer wheat normally sprouts from shed seeds, volunteer wheat control in farming should begin with ecological studies of these seeds. The objectives of this study were to clarify: 1) the forms of seeds shed during combine harvesting, and 2) the effects of these forms of seeds on wheat seed dormancy and longevity in the soil. Wheat seeds shed during combine harvesting consist of both loose seeds and unthreshed ears (or ear seeds). The head feeding combine lost 98 seeds/m^2 and 121.7 seeds/m^2 of loose seeds and ear seeds, respectively, while, the conventional combine lost 18.2 seeds/m^2 and 42.4 seeds/m^2 (Fig. 2). This shows that many of seeds from the unthreshed ears fall in the field during combine harvesting. The results of field experiments showed that the longevity of the seeds of wheat cultivars with a resistance to pre-harvest sprouting was greater than that of cultivars which showed a susceptibility to sprouting. The results also showed that the longevity of unthreshed ear seeds was longer than that of loose seeds in the soil (Table 2, Figs. 4 and 5). Shed seeds of unthreshed ears during wheat harvesting are numerous, thus making the volunteer problem worse in subsequent barley cultivation., The Weed Science Society of Japan
Weed Research, Japan, 1996 - Changes in Weed Seed Density in Soil of Paddy Fields under Successive Herbicide Applications
Sago Ryuichi; Komatsuzaki Masakazu, More than 30 years have passed since a herbicide effective for annual weeds was used to control weeds in Japan. However changes in the weed seed density in soils of paddy fields have not been clarified under successive herbicide applications. We analysed the seed density in soil during a period of 12 years in rice fields in Kanagawa prefecture where rice plants had been cultivated for more than 70 years and treated with herbicides for at least 30 years. The number of weed seeds was estimated based on the number of seedlings emerging from paddy soil samples collected from paddy fields. The soil samples were kept in shallow pots with water at a depth of 1cm in a green house without controlled temperature. Seedlings were identified, counted and removed periodically thoroughout the germination period. Emerged species included Lindernia procumbens (Krock.) Borbas., Elatine triandra Schk. var. japonicus Miq. ex Maxim., Rotala indica (Willd.) Koehne var. uliginosa (Miq.) Koehnne, Cyperus difformis L., Ammannia multiflora Roxb. and Monochoria vaginalis (Burm. f.) Presl var. plantaginea (Roxb.) Solms-Laub. Weed seed density in soil including 6 species ranged from 2, 264 to 10, 650per m2 among 9 plots in 1982. The weed seed density in soil was reduced from the above numbers in 1982 to 354-1, 847per m2 in 1994. The overall decline in the total number of weed seeds was 78.0% where herbicides had been applied every year. The decrease in the number of weed seeds in soil was ascribed to the fact that the reproduction of weed seeds was minimized during the 12 year period of herbicide application. The results on weed seedbank in relation to herbicide application may contribute to the development of a profitable and efficient weed management system., The Weed Science Society of Japan
Weed Research, Japan, 1995 - Studies on the Productivity and Operating Efficiency of Rice Cultibation Techniqve System by the Transplanting of Infant Seedlings (I) Acase study of the Cultivation Techniqve and the work Time of Infant seedling Cultivation
HAYASHI Hisayoshi; ENDO Oritaro; KOMATSUZAKI Masakazu; KONNO Hitoshi; YONEKAWA Kazunori; TAKAHASHI Toshio, Rice cultivation by the transplanting of infant seedlings was investigated in Ibaraki Prefecture. The results were as follows:
1) All the farmers used rockwool mats, while they have had different practices such as sowing rate, quantity of irrigation water, nursery period and so on. Days from sowing to the transplanting of seedlings varied from 10 to 20, and leaf age at transplanting from 2.4 to 3.2. Plant length of seedlings at transplanting was more than 8.0cm.
2) The average number of planted seedlings per hill was from 6.1 to 8.4. This figure was higher and variable than the usual one, 4 to 5. Higher percentage of vacant hill was brought about by higher fluctuation of the number of planted seedlings per hill.
3) The time needed for the rearing of infant seedlings was reduced to 49% of that for the rearing of young seedlings. But replanting time for infant seedling cultivation required 72% more than that of young seedling cultivation, because of high rate of vacans hill in infant seedling cultivation.
4) Rice yield in the infant seedling cultivation was nearly the same as that of young seedling cultivation. It is expected that low cultivation cost in infant seedling cultivation will be achieved by means of the improvement of transplanting accuracy., Japanese Society of Farm Work Research

KOMATSUZAKI Masakazu; ENDO Oritaro; OSAKI Kazuji; IKEDA Masanori; KUSAKABE Sumiko, The mixing of barley grain with volunteer wheat grain causes a serious problem in wheatsoybean-barley rotation. This report describes the relationship between the persistence of volunteer wheat and the mechanical weeding method in soybean culture. Control of volunteer wheat by inter-cultivation and ridging in soybean fields was effective. During the summer, most volunteer wheat plants died from drying or burying.
Inter-cultivation and ridging had killed wheat grain and wheat seedlings at a soil layer of 0-6cm deep. So when inter-cultivation and ridging were used in the cultivation of soybean, volunteer wheat decreased in fields where barley were planted by no tillage. But when inter-cultivation and ridging were also used in the cultivation of soybean, volunteer wheat increased in fields where barley were planted by rotary tillage. The reason why volunteer wheat increased in this field was that the wheat grain at a soil layer of 7-15cm deep was moved to suitable depth of emergence by rotary tillage.
In wheat-soybean-barley rotation, the best means were to prevent the mixing of barley grain with volunteer wheat grain by the combination of inter-cultivation with ridging in the cultivation of soybean, and by no tillage in the cultivation of barley., Japanese Society of Farm Work Research

KOMATSUZAKI Masakazu; ENDO Oritaro; OSAKI Kazuji, The contamination of barley grains by mixing of volunteer wheat grain causes a serious problem in barley production in the alternating cropping system between barley and wheat.
Effect of several kinds of soil applied herbicide and calcium cyanamid on germinated seeds of volunteer wheat was investigated in field experiments.
CAT, linulon and alachlor had little inhibitory effect while trifuralin incorporated with the soil greatly inhibited the growth of volunteer wheat during the summer. But thus herbicides had little inhibitory effect in autumn.
Calucium cyanamid incorporated with the soil promoted the emergence of volunteer wheat during the summer, and consequently the amount of volunteer wheat was slight in autumn.
Calucium cyanamid is thus quite useful for reducing the production of volunteer wheat during the autumn., Japanese Society of Farm Work Research

KOMATSUZAKI Masakazu; ENDO Oritaro; YOSHIZAKI Sigeru; OSAKI Kazuji, We investigated the separating characteristics of rough rice separaters to contaminated barley grains by mixing of volunteer wheat grains.
A principal factor in separation by rough rice separater was the difference ratio of grain length. So the difference ratio of grain length for barley and volunteer wheat grain were 1:0.78.
The performance of a rough rice separater for removing volunteer wheat grain from barley grain was poor, when separating the rice from the chuff. When the pan oscilation was 160rpm and pan slope, 16°, the rough rice separater efficiently removed volunteer wheat grain. So barley grain had met the standerd requirements at inspecting.
Then Newton's efficiency was 0.7. But thirty percent of the barley grain were discharged with wheat grain.
This operation was an emergency measure of prevention against the contamination of barley grain by mixing of volunteer wheat grain. Because barley grain loss on separating by rough rice separater resulted from falling in shipment of barley., Japanese Society of Farm Work Research

KOMATSUZAKI Masakazu; ENDO Oritaro; OSAKI Kazuji, Contamination of barley grain by mixing of volunteer wheat grain is now causing a serious problem in barley production under the alternating cropping system between barley and wheat. We chosed 8 upland fields of 7 farmers, whose growing area was rather large, and 7 upland fields converted from paddy fields by 4 farmers. We investigated the growth of volunteer wheat plants in those fields and discussed how harmhul volunteer wheat was to the production of barley in Ibaraki Prefecture.
The fields were investigated regarding cropped barley and wheat alternately so as to prevent a yield decrease caused by continuous cropping or the yellow mosaic disease.
In the fields where barley was planted after harvesting wheat, the contamination of barley grain by mixing of volunteer wheat grain occurred in the upland fields, regardless of summer cropping.
The volunteer wheat plants grew on both the inter-row spaces and ridges in the barley fields, so it was difficult to control volunteer wheat plants using cultivators.
The benefit of barley production decreased by 14-57% due to the contamination of barley grain by mixing of volunteer wheat grain. The alternate cropping system between barley and wheat has been of interest to the farmers in the areas infected with yellow mosaic. However, the best way to control volunteer wheat plants is still being sought., Japanese Society of Farm Work Research

KOMATSUZAKI Masakazu; ENDO Oritaro; OSAKI Kazuji, The objectives of this experiment are to clarify the relation between the growth of volunteer wheat plants and the cultivation methods under an alternating cropping system between barley and wheat.
In the fields where left in fallow or planted with buckwheat during the summer following the wheat harvest using a head-feeding combine, a great number of volunteer wheat plants had grown in the barley fields. This was observed, also, in the fields where upland rice or peanut were planted in the inter-row spaces between the wheat rows. The fields which were left in fallow or planted with buckwheat during the summer following the wheat harvest using a conventional combine harvester showed few volunteer wheat. Almost no volunteer wheat plants grew in fields which were plow-tilled followed rotary-tilling and where left in fallow after flooding the fields during the summer.
As a result of pot test, flooding the wheat grain for 5-7 days was effective in controlling volunteer wheat plants., Japanese Society of Farm Work Research
