The AAA evened the balance of supply and demand for farm commodities so that prices would support a decent purchasing power for farmers. This concept was known as "parity."
AAA controlled the supply of seven "basic crops" — corn, wheat, cotton, rice, peanuts, tobacco, and milk — by offering payments to farmers in return for farmers not planting those crops.
The AAA also became involved in assisting farmers ruined by the advent of the Dust Bowl in 1934.
