Fig. 1 Effects of different fertilization on soil particle size distribution characteristics of cultivated layer in slope farmland with different erosion degree Different capital letters indicated that there were significant differences in the same erosion degree and different management measures in the same cultivated-layer (P<0.05). Different lowercase letters indicated that the erosion degree of the same cultivated-layer was significantly different under the same management measures (P<0.05). The same as below
