Upstream Heroes » Missouri Bootheel » Corn Stalk Testing

 
The nitrogen status of a corn crop can be assessed by measuring nitrate concentrations in the lower portion of cornstalks at the end of the growing season. This finding led to the development of a tissue test that can be used to evaluate nitrogen management practices used in any field in any year. The test is called the “end-of-season cornstalk test.”
 
By assessing the levels of nitrate in cornstalks, producers can utilize this information as another tool for their fertilizer management. Results can be used in conjunction with soil maps, yield maps, varietal differences and the different forms of nitrogen fertilizer to give more precision to management decisions. These decisions affect the amount of nitrogen used in a given year and ultimately the profitability attained in farming operations.
