Timing is the Secret: Late-season nitrogen applications can pay off for corn growers-and irrigation makes it practical

摘要

Shifting nitrogen fertilizer appU-cations to later in the growing season pays off in higher yields as well as more efficient fertilizer use, according to a study by a Dumas, Texas, crop consultant.David Reinart compiled data from 781 corn fields for 11 years. He and his partner, Chris Cogbum, consult for about 25 growers as a sideline to their full-time jobs—Reinart with Wilbur-Ellis Company and Cogburn with National Sorghum Producers. Their company is called Better Harvest.
