Stalk Nitrate Testing

As we see corn get more yellow every day, we might want to know how we came out on nitrogen.  One way to make that estimate is to take a stalk nitrate test.  The test should be done after black layer or maturity.  I took Stalk nitrate test and also pulled soil samples for nitrogen analysis. It is possible that the tests will not match.  The soil test gives you a chance to do extra thinking about what might have gone wrong, or right.  No-Till Farmer has an article on late season nitrogen assessment.
