Effect of rice straw and swine manure biochar on N2O emission from paddy soil
Soil characteristics The physiochemical parameters of the paddy soil during the different rice growth stages are shown in Fig. 1. The pH value increased in the 1% RSBC, 1% SMBC, 5% RSBC and 5% SMBC-supplemented soils in that order compared to the control samples. Thus, SMBC had a greater alkalization effect than RSBC at both application […] More
