| Research Abstract |
Effects of organic farming with winter flooding on microbial communities were investigated in an experimental paddy field by molecular ecological techniques. Compositions and abundances of the bacterial, fungal and methanogenic archaeal communities in plow layer soil of the paddy field were not influenced conspicuously by the organic farming and winter flooding treatments. These findings indicate the sustainable and homeostatic features of paddy field ecosystem on the microbial aspects, which may contribute to the functions of paddy field such as conservation of environments and biodiversity.
