Soil organic matter (SOM) plays an important role in the continuous production and environmental conservation in arable soils. In particular, the decomposition of organic matter in soil might promote soil organic matter and fertility due to the mineralization of N. In this study, to evaluate the effect of organic matter amendment on the C mineralization and N dynamic, CO 2 -C flux, extractable N and N 2 O emission were determined using closed chamber for 4 weeks at 10, 15, 20°C of incubation temperature after the mixture of 2 Mg ha -1 rice straw compost and rye in sandy loam and clay loam. Regardless of soil texture, decomposition rates of rice straw compost and rye at 10~20°C of incubation temperature ranged from 0.9 to 3.8% and 8.8 to 20.3%, respectively. Rye application in soil increased NH 4 -N and NO 3 -N content as well as the N 2 O emission compared to the rice straw compost. After incubation for 4 weeks, total C content in two soils was higher in rice straw compost than in rye application. In conclusion, application of rice straw compost and rye to soil was able to improve the soil organic matter and fertility. However, organic matter including the recalcitrant compounds like rice straw compost would be effective on the management of soil organic matter and the reduction of greenhouse gases in soil.Key words: Soil organic matter, Soil respiration, Mineralization, N dynamic Total CO2 fluxes in sandy loam (A) and clay loam (B) by rice straw compost and rye application under closed chamber condition with air-temperature levels.

“…작물생산성 유지를 위해서는 토양 비옥도의 지속적인 관리 및 물리, 화 학적 특성의 개선의 이루어져야 하며, 이를 위한 여러가지 방안 중 유기물 함량의 증대는 가장 효과적인 방법 중 하나 로 평가되고 있다 (Navarro et al, 1993). Lee et al (2013)의 연구 결과에 의하면 논 토양에서 퇴비 및 무기질 비료의 장기연용에 의한 벼 수량은 퇴비 시용구에서 약 10년 이후 지속적인 수량 증가가 있었으며, 무기질 비료 시용구와 수 량차이가 없었다. 이는 퇴비 시용구에서의 지속적인 퇴비 시용에 의한 토양질 개선 및 유기물 함량 증가가 그 원인으 로 평가되고 있으며, 무기질 비료 시용구의 유기물 함량은 점차 감소하는 경향을 보였다.…”

The purpose of this study was to evaluate the effects of liquid manure to increase the yield of green manure in winter season, and to investigate the effect of green manure incorporation to increase the yield of maize grain and nutrient balance improvement in upland soil. The green manure used in this experiment was barley and hairy vetch with a mixed ratio of barley and hairy vetch (75:25), respectively. Liquid manure applied 0, 26, 52, 78, and 104 Mg ha -1 , respectively, and the half of the total amount was applied as basal fertilizer, and the other half was topdressing. Nitrogen inputs through liquid manure were 0, 7.1, 15.6, 21.5 and 28.4 kg ha -1 , respectively, and the phosphorus inputs were 0, 11.3, 22.6, 33.9 and 45.2 kg ha -1 , respectively. The yield of green manure crops increased significantly with the increase of liquid manure application, but the yield of hairy vetch decreased. In the summer season, the green manure crops were incorporated, and the compost was used in the conventional treatment. The yield of maize grain increased with increasing green manure yield. The yield of maize grain of green manure crops incorporation treatments was up to 81% compared to conventional cultivation treatment, however the two-year experiments showed an increase on maize grain yields in green manure incorporation treatment. In addition, the incorporation of green manure crops greatly improved the phosphorus balance in compared to conventional cultivation. Therefore, productivity improvement of green manure crops by utilizing liquid manure is thought to have significantly contributed to the improvement of maize grain yield and nutrient balance.

A variety of organic materials has been currently used for the nutrient management in agricultural land. However, there is little study to understand the impact of organic materials for crop production with soil bio-chemical properties. The aim of this research was to investigate the effect of organic materials using pepper crop (Capsicum annuum). Using oil-cake and amino acid fertilizer as organic materials, both soil characteristics such as bio-chemical properties and microbial community and pepper yield were tested for three years. The pepper was cultivated with four different treatments; Control (No fertilizer), NPK (inorganic fertilizer), OCF (Oil-cake), and (OCF+AAF) (Oil-cake with amino acid fertilizer). The result of soil properties showed that available phosphate content and microbial biomass were the highest in NPK and organic matter content was higher in OCF and OCF+AAF than NPK. Biochemical properties including activities of β -glucosidase, acid phosphatase, alkaline phosphatase and arylsulfatase were not different among all treated samples. For pepper yield, OCF and OCF+AAF showed 10 -40% less than NPK. Therefore, this study concludes that organic materials affect microbial biomass linked with organic matter contents and alter the soil microbial community.
