| Popis: | To investigate the effects of biochar on greenhouse gas (GHGs) emissions by static chamber-gas chromatograph method, a field experiment with three treatments was conducted: soil without fertilizer (CK), soil with conventional fertilizer (N) and soil with chemical fertilizer after biochar application (NB). The results showed that biochar reduced the N 2 O emission significantly and increased the absorption of CH 4 to soil. Compared to N, the N 2 O emission from NB decreased by 21.76%, and increased CH4 absorption by 55.31%, but no significant difference of CO 2 emission was showed between NB and N. Meanwhile biochar increased soil pH, total nitrogen content and organic carbon content, and also decreased soil NH 4 + -N content and bulk density. Biochar provided a new way to reduce GHGs from farmland and force air pollution of China’s agriculture. |
