Stalk Nitrate Test – What does the analysis really say?
I came across the following statement in this article, “Cornstalk nitrate test reveals nitrogen application accuracy” by Susan Winser, October 31, 2014
Each test has its role: The cornstalk nitrate test is a snapshot of how close you came to applying the most cost-effective N rate, and no more.
I think this statement shows the value of this analysis. As the article states, nitrogen application is a guessing game and the weather is a huge factor in determining if a grower has applied the appropriate amount of fertilizer. This summer has been an unusually cool and wet one. It would really be interesting as a grower to see how these conditions affect the amount of N in the corn stalk.
Consider running this test this fall. Check out past articles this month,
