Detailed explanation-1: -Unlike other agricultural researchers of his time, Dr. Carver saw the need to devise practical farming methods for this kind of farmer. He wanted to coax them away from cotton to such soil-enhancing, protein-rich crops as soybeans and peanuts and to teach them self-sufficiency and conservation.
Detailed explanation-2: -At Tuskegee, Carver developed his crop rotation method, which alternated nitrate-producing legumes such as peanuts and corn with cotton, which depletes the soil of its nutrients. His innovations have been credited with the South’s economic survival in the early part of the 20th century.
