Abstract

Economics, energy and the environment are three primary reasons to be concerned about nutrient management, especially nitrogen (N) management. Nitrogen ranks high on a list of sixteen nutrients needed for the health of most plants, but unfortunately it also ranks high as a contaminant of Nebraska’s surface and groundwater. Most other nutrients occur naturally in the soil. Besides nitrogen, phosphorus and potassium are the nutrients most often added to Nebraska soils.
