Nitrogen management

This will be my last report on Brownstown. Dr Steve Ebelhar presented this information and I find myself in agreement with him. Fall application of nitrogen is a crap shoot. Prompt incorporation of Urea is essential. His results concerning nitrogen additives is that most of them seem to work on the average, although he showed some results where they did not work. Nutrisphere is a mystery. It seemed to work but not in the way that the manufacturer claims. It would appear that Nitrification inhibitors, polymers, and urease inhibitors all seem to at least pay for themselves on the average. Also consider that they prevent some nitrate leaching into the ground water, because it is likely that more nitrate is taken up by the crop.
