The relationship between water quality and soil erosion cannot be overemphasized. Soil erosion and residue management, especially surface water runoff, influence water quality. A 1999 tillage survey sponsored by the Iowa Resource Management Partnership committee indicated the need for improvement in adopting conservation practices. The survey shows no increase in conservation tillage (no-till) for the period 1997-1999. Residue management is a critical component in controlling soil erosion.
