Effect of Biochar on NH₃ Volatilization and N₂O Emission in Brown Soil

Abstract:

In this study, we investigated the effect of biochar on NH₃ volatilization and N₂O emission in brown soil by using enclosed acid absorbing method and static chamber-gas chromatograph method. The results showed that without fertilizing, there was no significant effect of biochar effect on NH₃ volatilization and N₂O emissions but if biochar was combined with urea, a dramatic mitigation of which could be found. Biochar application was supposed to regulate urea-N transformation more easily than soil nitrogen. Under the conditions of this experiment, both NB20 (20 t·hm^-2 of biochar and conventional nitrogen fertilizer applied) and NB40 (40 t·hm^-2 of biochar and conventional nitrogen fertilizer applied) treatments reduced NH₃ volatilization and N₂O emissions significantly. By contrast of NB0 (single urea), the accumulated NH₃ volatilization and N₂O emissions of NB20 and NB40 decreased by 15.6% and 24.4% and by 21.76% and 19.56% respectively. Under conventional fertilization conditions (NB0), 10.35% of nitrogen in fertilizer was lost in the form of NH₃ and N₂O, and compared with NB0, NB20 and NB40 reduced nitrogen gaseous loss from fertilizer by 2.76% and 4.12% respectively.
