Nitrogen (N) is the nutrient most often deficient for crop production in Minnesota, and its use can result in substantial economic return for farmers.
However, when N inputs to the soil system exceed crop needs, there’s a possibility that excessive amounts of nitrate may enter either ground or surface water. By effectively managing nitrogen, growers can produce crops in a more profitable and environmentally friendly way.
