| Response of soil MBC and MBN to grazing treatment
By analyzing the soil MBC and MBN data, the detailed results were as
follows: 1) soil MBC and MBN contents in 2017 and 2019 showed a
consistent response to grazing, both showing that grazing increased soil
MBC and MBN contents, with a significant increase in MBC content under
heavy grazing; 2) there was an opposite trend in the increase in MBC and
MBN with grazing, with a rapid increase in MBC accompanied by a slow
trend in the increase in MBN, and vice versa(Figure(a)(b)(c)(d)).
