Nitrogen Management

Dr. Fernandez made his presentation on Nitrogen Management on Thursday. It was interesting to hear him discussing some of the same things i have learned since starting to work with Randy. He talked about how much N the crop needs. Corn takes up about 1.2 pounds times the number of bushels, hence the old benchmark recommendation. Fernandez suggested trying the PSNT. He also talked about stalk tests at black layer time. Another part of the presentation focused on the N-Rate Calculator. I like the PSNT and the N-Rate Calculator. Both come up with useful decision making data. You should be looking at the economics of it and trying to add some number values to what is actually going on in your fields. Here is the link to the N-Rate Calculator. http://extension.agron.iastate.edu/soilfertility/nrate.aspx
