Impacts of Giant Reed and Corncob Biochars on Nitrous Oxide Production
The influence of biochar on nitrogen transformation process in soils is largely unknown.Shortterm laboratory experiments were conducted to examine the production of nitrous oxide (N2O) in agricultural soil amended with different biochars at the rate of 5% (w/w),which were produced from giant reed and corncob at 300 and 500 oC (GR300,GR500,CC300 and CC500).The addition of GR300 and GR500 caused the reduction of N2O emission by 48.3% and 93.9%,respectively,while the addition of CC300 and CC500 caused the decrease of N2O emission by 99.5% and 99.3%,respectively.The results showed that the application of biochar may effectively reduce the emission of N2O from the agricultural soil.
