To investigate the effects of the mulch rate and rainfall intensity on soil loss, the soil loss versus the mulch rate for the two mulches under the three rainfall intensities were plotted as shown in Fig. 4. It was found that the soil loss decreased with the increased mulch rate for both RC and VGM plots. The soil loss increased with the rainfall intensity. The values of soil loss ranged from 1.5 t/ha to 16.7 t/ha with the rainfall intensity ranging from 35 t/ha to 95 mm/ h on the bare soil plot. In the RC plots, the soil loss reduced from 5.3 t/ha to 2.6 t/ha when the RC rate increased from 1.0 t/ha to 7.5 t/ ha for a rainfall intensity of 65 mm/h. Accordingly, in the VGM plots, the soil loss reduced from 4.9 t/ha to 3.1 t/ha
