Variable-rate nitrogen management (VRN) is a fairly hot topic right now. The outcome
of VRN promises improved efficiencies, economics, yields, and environmental
sustainability. As the scientific community learns more about the crop’s response to
fertilizer nitrogen and the soil’s ability to provide nitrogen, the complexity of providing VRN recommendations, which both maximize profitability and minimize
environmental risk, becomes more evident.
