Abstract

In arrays with more than one sensor, sensor uniformity is an issue. The impact of individual active NDVI sensor performance and array sensor number on the nitrogen (N) rates prescribed for wheat (Triticum aestivum L.) was studied. The NDVI data from an eight-sensor GreenSeekerTM array were obtained for two fields, and two fertilization algorithms were evaluated. Individual sensor N prescriptions differed significantly from each other, and there were differences by field and by algorithm. Reducing array sensor number heightened risk of poor agronomic, economic and environmental outcomes associated with a sensor that is operating at the tolerance edge.
