New Research on Corn Nitrogen Uptake

May 5, 2016

Nitrogen management in corn continues to evolve – with new ways to apply Nitrogen during the season, and new ways to measure it.  Our understanding of the corn plant’s appetite for Nitrogen is evolving as well.

DuPont researchers have written an article recently on Nitrogen Uptake in Corn. It’s a lengthy read but interesting.  If you don’t have time to read it, here are some of the main points:

  • Researchers are finding that modern corn hybrids are taking up nitrogen later into the season than older hybrids – to the tune of 29-40% more Nitrogen taken up after pollination when compared to older hybrids
  • Around 1/3 of a corn crop’s nitrogen may be taken up after pollination in modern corn production
  • Lower to average yielding environments still take up the vast majority of Nitrogen prior to pollination (as we’ve previously assumed)
  • High yield environments in particular may continue to take up significant amounts of nitrogen from the soil for several weeks after pollination
