| Outline of Final Research Achievements |
Organic rice farming system has been successfully established in a number of local regions in Japan. The outbreak of plant diseases is effectively suppressed in the organic farming system. The features common to nine organic farmed soils used for rice nursery cultivation, which were supplied by nine independent organic rice farmers, were analyzed. The emergence of bacterial seedling diseases was equally suppressed in nine organic farmed soils, but not two conventional soils. On physicochemical analysis of those soils, there was not either any component common to nine organic soils or difference between organic soils and control conventional soils. On the other hands, bacterial and fungal microbiome analysis indicated that their populations in nine organic soils were more diverse than those in conventional soils. The diverse of microbiome may play an indispensable role for suppressing rice seedling diseases in organic agriculture.
