Alfalfa is a $10 billion-a-year crop in the United States and is produced in all 50 states. It fixes nitrogen in the soil, saving an estimated $457 million a year in fertilizer costs, and reduces pests and plant pathogens when rotated between crops of corn and soybeans. Its roots also capture nutrients in the soil so that fewer of them flow into waterways.
