Rescue Nitrogen Application Often Booata Corn Yields

摘要

Wet weather causes nitrogen losses somewhere virtually every year. In 2008 and 2009, very wet weather caused major nitrogen losses in a huge chunk of the Corn Belt. "My rule of thumb is that more than 16 inches of rain from April through June - or more than a foot in May and June -will lead to nitrogen deficiency problems in a substantial number of cornfields," says University of Missouri agronomist Peter Scharf.
