George Washington Carver was a scientist and botanist who sought to solve the agricultural problems of the American south. As a result of the single-crop system in use where most farmers planted only tobacco or cotton, the soil had been depleted of the necessary nutrients. Carver discovered that if new crops, rich in nitrogen and proteins, were planted the soil would recover.
He petitioned the Southern farmers to plant soybeans, sweet potatoes, and peanuts. These crops grew well and solved the problem of the soil, however, there was no market for their sale. Carver tried to solve this problem by establishing a market for these goods by finding new uses for the plants, specifically peanuts, and sweet potatoes.
