| Abstract: | Erodibility (factor K) of seven representative soils under dry and moisture conditions in subtropic China was studied by means of the rainfall simulator. The results showed that difference was obvious between erodibilities (factor K) of the same soils under dry and moisture conditions. Value K of fanning soils is higher than that of non-farming soils. |
