Clean Water Iowa has developed effective nutrient reduction practices through nitrogen & phosphorus management, land use, and edge-of-field/erosion control.
Overview of the various nutrient mitigation practices promoted by the Iowa Nutrient Reduction Strategy: Nutrient management, Land use change, Edge-of-field practices are described and effectiveness measures are provided.

Overview of various economic benefits associated with the use of cover crops.
The Midwest Cover Crops Council site provides information currently available on the use of cover crops in the Midwestern United States. The Council's goal is to expand upon the available information by working together as a regional collective of researchers, educators, farmers, and agribusinesses, ultimately leading to an increase in the use of cover crops on agricultural lands.

This web site provides a process to calculate economic return to N application with different nitrogen and corn prices and to find profitable N rates directly from recent N rate research data. The method used follows a regional approach for determining corn N rate guidelines that is implemented in several Corn Belt states.
