Research Abstract

The amounts of organic carbon from rice root exudates to solution or soil were successfully measured. In the hydroponic culture experiment, the difference of amounts of organic carbon per dry biomass exuded from rice root was more remarkably than that calculating by per plant among 8 kinds of rice cultivars. In the sandy soil culture experiment, the total organic carbon and CH4 in soil solution, and CH4 emissions from the plants were significant difference among 3 kinds of rice cultivars. Furthermore, after rice planted in the C4 soil which organic carbon was low at 0.5% for one season, the soil organic carbon from rice root exudates was measured by stable isotope nature abundance (delta 13C) method. As the results, the soil organic carbon from rice plant was 11.6% of the total assimilation carbon (plant biomass carbon). Approximately 10% of new soil organic carbon was translocated from the roots during one rice growth season.
