Stalk Nitrate Testing is a very popular test this time of the year.  It gives growers an idea of the effectiveness of their nitrogen applications for the current growing season.  There is a very good reference guide on the Purdue University Agronomy Site, “End-of-Season Corn Stalk Nitrate Test” which talks about the whole process and looks at what type of nitrogen levels you should be looking for.
