The Agricultural Adjustment Act was a federal law of the United States, which was part of the New Deal program to restore the country's agricultural bonanza during the Great Depression.
It was approved by the United States Congress in 1933, in an attempt to reduce the rural production of certain necessities, in order to raise prices.
