| Research Abstract |
Effect of an alternate wetting and drying(AWD) water-saving practice on the methanogenic archaeal community in a paddy field soil was investigated by molecular ecological analyses. Dynamics of the community structure and metabolic activity of methanogenic archaea tended to be different depending on water management, and distinct members characterized the each treatment. However, population of methanogenic archaea was not different between the treatments. This study indicated that process of methane production via decomposition of organic materials in the AWD paddy field soil was different from the traditional paddy field soil.
