Calculating USLE (#3-5): Assume maximum soil loss of 5 tons/acre all questions. Use the tabular data to help answer the questions. C-factors are split into Tables 4A and 4B therefore C-factor = 4A 4B values. Show your calculations for full points. 3. In a Hays Co. pasture with sandy clay loam soil what is the maximum allowable slope if the field is 800 ft long, using no-till going up-down slope? With horticultural crops? 4. What is the ideal K-factor for strip cropped and contoured, fall plowed maize with LS-factor 0.7582. With wheat? 5. What crop would be best suited for a ridge tilled, contoured, loam soil, 1600ft field with a 5% slope? Which would be the worst suited crop?
