Long term compost fertilization in paddy field ecosystem is essential to maintain rice yield, soil function and fertility. However, rice fields are a major source of methane production. Monitoring long term fertilizer application and its effects on soil chemistry and the functional microbial populations are important in understanding methanogenesis and methane oxidation in paddy ecosystems. This study evaluates the changes in soil chemistry in paddy fields under long term compost fertilization and their effect on the abundance of methanegenesis, methane oxidation, and methanol oxidation related genes, namely mcrA, pmoA, and mxaF genes, respectively. Soil sampling was done on compost (Com), NPK+compost (NPKCom) and unfertilized (NF) paddy fields. The abundance of mcrA, pmoA and mxaF genes were measured using quantitative PCR (qPCR). Results show that long term compost and NPK+compost fertilization alter the soil chemistry of paddy fields with an overall increase in the organic matter (OM), total nitrogen (TN), P₂O<SUB>5</SUB ... 전체 초록 보기
