| Abstract: |
| Biochar has been shown to improve soil physical, chemical and microbiological properties, and thus may inhibit greenhouse gas emission from soils. A pot experiment was conducted to investigate the impact of bamboo biochar applications on methane（CH4） and nitrous oxide（N2O） emission from a paddy soil collected from Ningshao plain, Zhejiang Province. The experimental results showed that applying bamboo-char significantly reduced the emission of methane and nitrous oxide compared with the control. There was a positive relationship between the emission and biochar rates. Rice yield was higher in the biochar treatments than in both the control and traditional fertilization treatments. In the biochar treatments, the total seasonal emissions of CH4 and N2O decreased by 58.2%~91.7% and 25.8%~83.8%, respectively, compared with the control; and by 64.3%~92.9% and 72.3%~93.9%, respectively, compared with the traditional fertilization. Our data suggest that biochar from manufacture wastes could be used to reduce greenhouse gas emission. |
