Wisconsin researcher studies nitrogen-fixing corn

A University of Wisconsin researcher is hoping to use the traits from a variety of corn found in the Mexican mountains to reduce the need for nitrogen fertilizer.Jean-Michel Ané tells Brownfield the giant corn can stand more than 16 feet tall and unlike most corn, it can fix much of its own nitrogen similar to legumes.  “Right before tasseling, that corn gets 40-50 percent of its nitrogen from the air.”
