Effects of Different Fertilizer Applications on the Emission of Methane and Nitrous Oxide from Paddy Field and Its Mitigation Measures of Emission

Han Peng-fei

Abstract

The emissions of methane(CH4) and nitrous oxide(N2O) from paddy field are affected by several environmental factors,such as water,temperature,status of fertilizer application,organic matter content,pH value,Eh.However,water and fertilizers are two main driving factors of gas emission in greenhouse of paddy field.The effects of different fertilizer applications on the emission of CH4 and N2O from paddy field were reviewed.And some corresponding emission mitigation measures of greenhouse gas were put forward.
