Intermittent irrigation changes production, oxidation, and emission of CH4 in paddy fields determined with stable carbon isotope technique

Intermittent irrigation is an important option for mitigating CH4 emissions from paddy fields. In order to better understand its controlling processes in CH4 emission, CH4 fluxes, CH4 production and oxidation potentials in paddy soils, and 13C-isotopic signatures of CH4 were observed in field and in...
