====== Erosion Control Limits ====== To maintain or improve soil productivity, erosion must be kept within acceptable limits.† ^Percent Slope ^Minimum Percent Ground Cover Needed| |0 |0 | |5 |10 | |10 |40 | |15 |60 | |20 |70 | |25 |75 | |30 |80 | † This table was constructed using the Universal Soil Loss Equation and the southeast Area, Erosion Bank. The goal is to keep erosion to approximately 12 tons/acre total for the recovery period of the disturbance.
