Farmers and many others are well aware that legumes such as soybeans are able to provide some of their own nitrogen through an association with symbiotic bacteria. Corn production requires the application of nitrogen fertilizers, which are costly in several ways. Listen to UC-Davis professor Dr. Allen Bennet describe his team's discovery of corn that is able to fix nitrogen from the atmosphere, and the future implications of his research.
