초록
The effect of biochar application on soil physics and nitrous oxide (N2O) emission from upland soil for broccoli cultivation was investigated. Sesame straw biochar (SB) was applied at amounts 0 (IF), 50 (SB50), 100 (SB100), 200 (SB200) kg 10a-1, respectively. SB addition to the upland soil decreased bulk density, and increased porosity and soil respiration. The N2O emission rates in all treatments were higher in the order of IF ≧ SB50 ＞ SB100 ≧ SB200 treatments. Global warming potential in SB200 treatment decreased by 15.1% compared to IF treatment. Therefore, SB application in upland soil can improve soil physics and reduce N2O emission.
