Methane emission from irrigated and intensively managed rice fields in Central Luzon (Philippines)tilizer in place of urea resulted in a 25-36% reduction in CH. emissions. Phosphogypsum reduced CH. emissions by 72% when applied in combination with urea fertilizer. Midseason drainage reduced CH. , emission by 43%, which can be explained by the influx of oxygen into the soil. The practice of direc

Methane emissions and mitigation options in irrigated rice fields in southeast Chinalooding; CH. emissions could further be reduced by intermittent irrigation, yielding a 30% reduction as compared with midseason drainage. The incorporation of organic amendments promoted CH. emission, but the amount of emission varied with the type of organic material and application method. Methane
