There is more than one way to skin a cat, right?
Did you read the Zone Analytics of a management zone field. How can you use that? Well one way is to make nutrient uptake layers from the zone and actual yield but use it to replace the nitrogen by the zone. There’s a good correlation with those zones so lets use that knowledge to implement some variable rate N for the next crop.
This example shows the yield goals for each zone derived from the previous crop to establish a formula based Urea application for the next crop. The application is split into 50% application at planting and two in-crop applications.
On the final page we download the product report and the shape files and send to the operator.
