Although Iowa farmers have made good progress in applying soil conservation practices, much soil and water is still lost from farm land. Increased acres of row crops with a corresponding decrease in meadow and pasture land has caused concern due to increased erosion by wind and water. The leaving of crop residues on the surface of the soil instead of covering them by plowing can provide good soil protection. Mulch tillage techniques on continuous row cropped land can equal crop rotations with meadow in controlling soil loss. Crop residues left on the soil surface over winter also helps to provide food and some cover for many species of wildlife.
