Abstract:
Biochar addition to agricultural soil has drawn much attention to mitigate atmospheric carbon through increased biogenic carbon storage and reduction of greenhouse gas emission. In laboratory incubation study, we measured biochar application effect on fluxes of N2O, CO2, and CH4 by different types of N fertilizers applied to sugarcane and rice paddy soils during a 3 month. In addition, field trials of biochar application were performed in rice and sugarcane fields to measure emission of N2O, CO2, and CH4 with a closed chamber method throughout the whole rice and sugarcane growing season. Total N2O emissions were sharply decreased by in biochar amended soils with N fertilization. Results of laboratory incubation and field studies on biochar application effect on greenhouse gas emission will be presented.
