Corn growers continually face many production challenges including low grain prices, high input prices and regulatory pressure to minimize nutrient losses to the environment. Nitrogen management figures prominently into these challenges with questions surrounding selection of N fertilizer rate. The objective of this study was to evaluate the profitability and efficiency of N rate selection tools currently used in Wisconsin.
