There were no significant differences in soil bulk density between the
grazing methods and GE, but soil bulk density in MG was significantly
higher than that in CG (P <0.05, Table 1). Soil pH
decreased with the deepening of the soil layer in all methods; the mean
pH of MG was significantly higher than that observed in the other
methods (P <0.05). The
SOC of GE was higher than that of
all grazing methods in each soil layer, being significantly higher at
0–10 and 20–30 cm (P <0.05). Grazing methods decreased
the mean SOC by 41.39%–50.17% compared to that obtained using GE, but
there were no differences among the grazing methods
(P >0.05, Table 1). Mean DOC values were not
significantly different among GE, CG, and RG; however, they were
significantly higher than that of MG (P <0.05). LOC
obtained with grazing methods was higher than that associated with GE at
each soil depth, and the mean LOC of CG was significantly higher than
that of GE (P <0.05).
Grazing significantly increased
the mean TN in CG and RG, as compared to that in GE
(P <0.05). TP was highest in the 20–30 cm soil depth,
except for RG; grazing significantly increased TP in each soil layer,
and there were
