| Response of soil properties to grazing treatment
Through testing and analyzing the samples and compiling the data, the
following results were obtained: 1) grazing decreased soil SOM, TN, pH,
and SMC contents, reaching the lowest level under moderate grazing, but
all three had a slight upward trend under heavy grazing, and especially
soil SMC was significantly increased under the effect of heavy grazing
(Figure (a)(b)(c)(e)); 2) grazing decreased soil TP content, and the
decrease decreased with increasing grazing intensity(Figure (d)); 3)
grazing increased soil C/N ratio, and soil C/N ratio increased very
significantly under moderate grazing(Figure (f)).
