Losses of various forms of the major nutrients, nitrogen (N) and phosphorus (P), from agricultural lands to water resources in the Upper Mississippi River Sub-Basin and throughout the Corn Belt threaten the health of both humans and aquatic systems. In addition, nutrient losses from the five-state region, Minnesota, Wisconsin, Illinois, Iowa, and Missouri, as well as other Corn-Belt states, contribute to hypoxia in the northern Gulf of Mexico. Currently, the States, with guidance from the U.S. Environmental Protection Agency (EPA) are developing water quality criteria for nutrients in flowing (rivers and streams) and standing (lakes and reservoirs) waters. This website will serve as a receptacle for and the exchange of information towards that goal.
