According to the soil survey of a given soil it has a T-value of 5.0, soil erodibility factor of 0.18, rainfall factor of 135, and topographical factor of 0.6. the grower uses conventional tillage to grow continuous corn and ploughs up and down the slope. The farmer did not use any support practices and the value of crop management factor is 0.37.
i. Compute the soil loss
ii. What if the farmer changes from no support practices to contour ploughing of a factor of 0.5? compute the soil loss
