Alternate wetting and drying (AWD) irrigation is effective at reducing methane (CH 4 ) emissions in rice cultivation. To investigate the effect of the infiltration rate on AWD effectiveness in terms of CH 4 emissions, rice was cultivated in pots with three different infiltration rates under AWD. Under intermittent irrigation, the soil was more oxidative than is generally required for CH 4 production (redox potential [Eh] > −15...

Reducing methane (CH 4 ) emissions from paddy fields that contribute to the greenhouse effect has been addressed recently through the application of the alternate wetting and drying irrigation method. However, in poorly drained areas, such as the Red River Delta in Vietnam, the soil cannot be dried immediately, and so CH 4 can continue to be produced unintentionally. Therefore, the purpose of this case study was to identify th...
