Description:
Biochar reduces yield-scaled emissions of reactive nitrogen gases from vegetable soils across China Changhua Fan, Hao Chen, Bo Li, and Zhengqin Xiong Biogeosciences, 14, 2851-2863, https://doi.org/10.5194/bg-14-2851-2017, 2017 Intensive vegetable fields suffered very low N use efficiency and very high N 2 O emissions as compared to other ecosystems. We have demonstrated that two contrasting biochars affected gaseous reactive nitrogen intensity (N 2 O, NO, NH 3 , yield) across four major vegetable soils in China. Biochar affects gaseous Nr or yield largely depending on soil types. Both wheat straw biochar ( B w ) and swine manure biochar ( B m ) decreased GNI with Bw mitigated gaseous Nr, whereas Bm improved yield.
