•We investigated the effect of air-dried and composted manures on CH4 emission in rice field.•Compost leads to ∼50% mitigation of CH4 emission compared to air-dried manures.•Labile organic C content was higher in manure-treated soils than in composted manures.•C fraction in lighter aggregates of man...
