Nitrogen Sensing Tools to Improve N use Efficiency in Corn Production Nitrogen use efficiency is the percentage of applied nitrogen that is taken up by the crop. Under normal corn production conditions nitrogen use efficiency is seldom higher than 60%. Technologies are now available that allows producers and crop consultants to rapidly assess in-season crop nitrogen status and adjust side-dress N fertilizer accordingly. The goal of this technology is to apply N in only the areas of the field that exhibit N stress thus improving nitrogen use efficiency. This presentation will discuss research results and sensor usefulness in the eastern Corn-belt. Greg SchwabExtension Soils Specialist |
