Excerpt from the report: Recent developments in tillage methods for row crops offer effective ways to combat runoff and erosion. The development of these methods comes at an opportune time because continuous row cropping is increasing in many sections of the Corn Belt. The potential erosion hazard increases when sod-based rotations on sloping soils are replaced by continuous row crops. Sod crops protect the soil from climatic factors that cause erosion. In addition, sod crops improve soil structure for succeeding row crops. The increased use of fertilizer and higher plant populations improve crop yields and increase residue production. Thus the hazard of erosion while the land is in row crops is reduced. These practices have not, however, eliminated the hazard, and therefore, other soil-conserving practices need to be considered.
