Abstract: This study applied the DNDC-Rice model and simulated against field observation in Thailand. Simulated CH4 emission data shown acceptable results compared to field observation recorded. Rice straw incorporation into field plays important role on CH4 emission by continuous increase soil organic carbon as well as soil iron contents, consequently to low soil Eh which is suitable for CH4 production. Higher amount of rice straw applied induces higher CH4 emission vice versa. Therefore, reduction of rice straw amount incorporation into soil is possible practical mitigation options for CH4 production.
