Managing for Profit
New tool determines where nitrogen is most needed
There’s a new tool on the market for managing nitrogen loss. There is a lot of that happening this season because of unusually wet weather in some areas. University of Missouri plant science professor Peter Scharf has advice about adequate nutrients in the crop.
“Make sure your corn does not run out of nitrogen,” Scharf told Brownfield’s Julie Harker.
Scarf has helped to develop a tool called NVisionAg to help growers decide whether they need more nitrogen fertilizer. It uses aerial images showing specific degrees of nitrogen loss within a field. From those images nitrogen rate control files are made to determine which fields, and more precisely, which areas within a field need nitrogen applied and which do not.
