COMMERCE and Sharkey soils were found to be highly erodible. Simulated rainfall tests resulted in soil erodibility factors (K) of 0.63 and 0.44 (English units) respectively for Commerce and Sharkey soils; metric K's are 0.81 and 0.57. A cropping factor (C) for a conven-tional four-year sugarcane cropping system was found to be 0.41. Soil erodibility factors derived from field data were compared with those determined with the Wischmeier nomograph. Due to good aggregation and aggregate stability these silt loam and silty clay soils were found to have apparent sandy loam surface textures, and to behave more like sandy loam than like silt and clay soils during the erosion process.
