Abstract

Methane (CH4) emissions from Chinese paddy soil (Zhejiang province) were measured over the rice growing seasons. Different fertilizers (organic and chemical) were applied, emissions of methane were high during two periods (05 days after peak tillering and 07 days after heading flowering stage) and significant effects of fertilizers were observed. Methanogenic activities in soils treated with organic manure were obviously higher than those with chemical fertilizers. Among the organic manure fields the maximum methane emission from green manure, biogas residue and beef manure treatment were 52, 20 and 19 times, respectively of that given by control, and among chemical fertilizers it was NH4HCO3 > CO(NH2)2 > (NH4)2SO4 > NH4Cl >NaNO3 with 2.4, 2, 1.5, 1.3, and 0.2 times, respectively of that from control.

Key words: Methane emission, field, methanogenic flora flooded rice, organic and chemical fertilizers.
