Note: Different capital letters indicate significant differences (P<0.05) between different soil layers for the same method; different lowercase letters indicate significant differences (P<0.05) between the same soil layers for different methods. Values are means ± SE.
significant differences among grazing methods: CG>RG>MG (P <0.05). Grazing significantly decreased the C/N and C/P ratios at each soil depth (P <0.05) along with the mean N/P ratio (P >0.05), but there were no significant effects among the grazing methods (Table 1).
