This article was posted by No-Till Farmer concerning nitrogen management. The advice is similar to my own. There is some advice about rescue treatments that is interesting. I say you can't rely on rescue. Try to get it right the first time. Fall applications are most likely to nitrify early. One of the most important N management tools is drainage. Nitrogen dentrifies rather quickly under wet conditions, so doing your best to manage soil moisture will help you manage nitrogen as well. Spring applications and sidedressing are most economical and also most like to maintain adequate nitrogen for the crop. You do need to be prepared to apply when the conditions are right if you sidedress. It is not all bad to start sidedressing as soon as corn emerges.
