Effective Soil Erosion Prevention Methods and Techniques

Surface residue reduces erosion, while reduced tillage methods result in less erosion. Corn returns more residue than soybeans, leading to decreased soil loss. Roller-crimper creates a weed-suppressing cover crop mat for planting.

  1. FP 45 40 FC 35 soil loss (tons/acre) FP 30 NT 25 FC 20 15 NT 10 0 10 20 30 40 50 60 70 5 residue cover of soil surface (%) 0 This figure shows that: • surface residue reduces erosion, • reduced tillage (chisel and no-till) leaves more residue and results in less erosion than plowing, and • corn (circled) returns more residue than soybeans. Figure 16.2. Soil erosion dramatically decreases with increasing surface cover. Note: FP = fall plow, FC = fall chisel, NT = no-till; circles = corn, no circles = soybeans. Modified from Manuring (1979).
