Fertilizer-N is a big investment for crop production in Nebraska and elsewhere. After harvest, growers tend to plan their fertilizer-N management for the next year’s crop. But the question is how much nitrogen can they apply to get the most profit from their fertilizer-N investment?
Fall fertilizer applications offer cost savings and time management benefits, but also may contribute to increased soil nitrate-N leaching. With Nebraska's high soil moisture levels, consider these suggestions when applying nitrogen this fall.
The Nebraska Extension Circular, Nutrient Management Suggestions for Corn (EC117), has been updated to account for residual soil nitrate-N and provide an alternative for determining fertilizer-P rates.
