Effects of Biochar Combined with Nitrogen Fertilizer Application on Pepper Yield, Quality and Rhizosphere Soil Microbial Community Diversity.

Effects of Different Biochar and Nitrogen Fertilizer Combined Application on Soluble Salt Ion Content in Pepper Rhizosphere Soil As shown in Table 4 , both nitrogen (N) application and biochar (B) application had extremely significant effects on the content of each ion. nitrogen fertilizer and biochar could increase the contents of K + , Ca 2+ and Mg 2+ , and decrease the contents of Na + and Cl − ; the combined application of nitrogen fertilizer and biochar had a significant effect on the content of K + , among which the B1N3 t
