George Washington Carver is one of the most famous botanists, or plant scientists, in U.S. history. His discovery of nitrogen fixation essentially saved many of the fields in the American South. Nitrogen fixation is where legumes, like soybeans, alfalfa, and peanuts are planted every other year in cotton fields to enrich the soil with beneficial nitrogen. Part of the "Into the Outdoors" series.
