Technical Abstract: The increased efficiency of nitrogen fertilizer (N) use has been a long-term goal in reduction of nitrate contamination in the state of Nebraska. Preliminary research has shown sensor based in-season application of nitrogen has the ability to be economic and environmentally viable. Although benefits have been published there is an opportunity for increased accuracy of N application through the integration of preprocessed georeferenced management zones. In-season sensor based N application relies on the instantaneous crop canopy health to determine recommendation. Yield potential in not only a factor of crop health but also of soil properties. Using soil electrical conductivity (EC) readings along with landscape attributes allow for a generalized estimation of soil properties and can allow for N recommendations to be based on crop status and yield potential.
