Unique Corn Variety Can Take Nitrogen Out Of The Air, Reducing Need For Artificial Fertilizers That Can Cause Runoff

Researchers at the University of Wisconsin-Madison have helped discover a corn variety that could reduce the amount of nitrogen fertilizer farmers need to spread.

The tropical variety of corn has been grown in Oaxaca, Mexico for thousands of years. Because the area’s soils have little nitrogen, the corn has adapted over the years, developing a system for taking nitrogen out of the air.

This process, called nitrogen fixation, is something researchers around the world have been working to identify and breed into corn for more than 100 years.
