This article traces the legislative origins, implementation, major amendments, and institutional evolution of the Agricultural Adjustment Act (AAA) from its enactment in 1933 through the postwar consolidation of federal farm policy. For the broader program of which it was a part, see New Deal. For contested interpretations of its economic effects, see AAA - Economic Effects Debate. For its constitutional history, see AAA - Constitutionality Debate.

American agriculture entered a sustained depression nearly a decade before the broader economy collapsed in 1929. During World War I, European demand had driven farm commodity prices to historic highs, and American farmers expanded acreage and took on debt accordingly. When European agricultural production recovered after the war, export markets contracted sharply. Commodity prices fell throughout the 1920s while farm debt, machinery costs, and land values remained elevated. Net farm income dropped from approximately $9 billion in 1919 to roughly $4 billion by 1929.¹⁾

The stock market crash of October 1929 and the ensuing depression accelerated the farm crisis. Between 1929 and 1932, gross farm income fell by more than 50 percent. Corn prices dropped to under 15 cents per bushel in some markets; wheat fell below 30 cents; cotton reached 5 cents per pound - all below production cost for most growers.²⁾ Mortgage foreclosures spread across the Midwest and South. Organized farmers in Iowa and elsewhere conducted “penny auctions” to obstruct foreclosure sales and, in some instances, physically prevented sheriffs from conducting them.

Several policy proposals circulated in the late 1920s and early 1930s in response to the farm crisis. The McNary-Haugen plan, twice passed by Congress and twice vetoed by President Calvin Coolidge (1927, 1928), proposed a two-price system in which the federal government would purchase surplus commodities at a domestic parity price and sell the surplus abroad at world prices, with farmers paying an equalization fee to cover the loss. The domestic allotment plan, developed by agricultural economists including Milburn Wilson and John Black, proposed instead to control production directly, limiting supply to raise domestic prices without the export mechanism.³⁾ The domestic allotment approach formed the conceptual core of the legislation that became the AAA.

Roosevelt entered office on March 4, 1933, with agriculture among his stated first priorities. Representatives of major farm organizations - the American Farm Bureau Federation, the National Grange, and the Farmers' Union - met with incoming administration officials in February and March 1933 and reached agreement on a bill framework. The resulting draft legislation gave the Secretary of Agriculture broad authority to choose among several mechanisms - production controls, marketing agreements, and processing taxes - rather than mandating a single approach.

Congress passed the Agricultural Adjustment Act on May 12, 1933, and Roosevelt signed it the same day. The act declared a national emergency in agriculture and established the Agricultural Adjustment Administration within the Department of Agriculture. Its stated goal was to restore farm purchasing power to “parity” - defined as the ratio of commodity prices to the prices farmers paid for goods during the base period of August 1909 to July 1914, a period of relative agricultural prosperity.⁴⁾

The act's primary mechanisms were:

• Production control contracts: Farmers agreed to reduce acreage planted in covered commodities in exchange for benefit payments funded by processing taxes levied on the first domestic processing of those commodities.
• Marketing agreements and licenses: The Secretary could regulate the handling and marketing of agricultural commodities to stabilize prices.
• Commodity loans: The Commodity Credit Corporation, established by executive order in October 1933, made price-support loans allowing farmers to store commodities rather than sell into a depressed market.

Covered commodities initially included wheat, cotton, field corn, hogs, rice, tobacco, and milk and dairy products. Congress added other commodities in subsequent amendments.

Henry A. Wallace, appointed Secretary of Agriculture, and Chester Davis, who became AAA administrator in 1933, oversaw the act's initial implementation. The first major program action was the emergency cotton plow-up of the summer of 1933. Because the cotton crop was already planted when the act passed, the AAA contracted with farmers to plow under approximately 10.4 million acres of growing cotton in exchange for benefit payments, destroying an estimated one-quarter of the crop in the field.⁵⁾ A parallel program in the fall of 1933 involved the slaughter of approximately 6 million pigs and 220,000 sows to reduce pork supplies, an action that drew public criticism as wasteful amid widespread poverty and hunger.

The AAA established county and local committees - predominantly composed of established, often larger-scale farmers - to administer allotment programs at the local level. This decentralized structure gave local committees significant discretion over how acreage reductions were apportioned among landlords and tenants on the same property.

Production controls combined with drought conditions reduced output in several major commodities. Cotton production fell from 13.0 million bales in 1932 to 9.6 million bales in 1934. Wheat production fell sharply. Commodity prices rose from their 1932-1933 lows, though they remained below parity targets throughout the decade.

The displacement of sharecroppers and tenant farmers under the cotton program drew organized opposition. The Southern Tenant Farmers' Union, founded in Arkansas in 1934, arose directly in response to AAA acreage reduction contracts that allowed landlords to pocket benefit payments while evicting tenants whose labor was no longer needed on reduced acreage.

In 1935, a purge of the AAA's legal section followed internal disputes over the treatment of sharecroppers and tenant farmers in the cotton program. Legal section attorneys, including Alger Hiss, had drafted an interpretation of the cotton contracts requiring landlords to keep the same tenants on the land during the contract period. Secretary Wallace and Chester Davis rejected this interpretation and dismissed the legal section's leadership, including Jerome Frank, in February 1935.⁶⁾

The AAA's processing tax mechanism faced legal challenge from its inception. The Supreme Court accepted a case brought by receivers of the Hoosac Mills Corporation, a textile processor, contesting the processing tax on cotton.

On January 6, 1936, the Supreme Court decided United States v. Butler by a 6-3 vote, invalidating the AAA's processing tax and production control provisions. Writing for the majority, Justice Owen Roberts held that the processing tax and the production control contracts it funded constituted an unconstitutional regulation of agricultural production - a local activity reserved to the states under the Tenth Amendment - rather than a lawful exercise of the congressional taxing and spending power. Justice Harlan Fiske Stone, joined by Justices Louis Brandeis and Benjamin Cardozo, dissented, arguing that the majority had incorrectly restricted the scope of the spending power.⁷⁾

Congress responded to Butler within weeks. The Soil Conservation and Domestic Allotment Act, signed February 29, 1936, replaced the invalidated AAA mechanism with a soil conservation framework. Under the new act, the federal government made payments to farmers who shifted acreage from “soil-depleting” crops - which corresponded closely to the surplus commodities targeted by the original AAA - to “soil-conserving” crops such as grasses and legumes. The conservation rationale was intended to bring the program within accepted constitutional limits on federal spending. Funding shifted from processing taxes to general appropriations.⁸⁾

Congress enacted a second Agricultural Adjustment Act on February 16, 1938, establishing a more comprehensive and permanent framework for federal farm price support. The 1938 act rested on the commerce power rather than the taxing power, reflecting the constitutional landscape after the Supreme Court's shift in NLRB v. Jones & Laughlin Steel Corp. (1937) and the retirement of several conservative justices.

Major provisions of the 1938 act included:

• Mandatory marketing quotas: For wheat, cotton, corn, tobacco, and rice, marketing quotas could be imposed when supplies reached specified levels, subject to approval by two-thirds of affected farmers in a referendum.
• Acreage allotments: Allotments established limits on the acreage each farm could devote to covered commodities.
• Parity payments: Direct payments compensated farmers for the difference between market prices and parity when commodity prices fell below 75 percent of parity.
• Ever-normal granary: The act institutionalized commodity storage to stabilize supplies across years, a concept Wallace had drawn from the biblical account of Joseph's grain reserves in Egypt.
• Federal Crop Insurance: The act established a pilot crop insurance program for wheat.⁹⁾

The Supreme Court upheld the 1938 act's wheat marketing quota provisions in Wickard v. Filburn (1942), ruling that even wheat grown for home consumption could be regulated under the Commerce Clause because it affected interstate commerce in the aggregate.¹⁰⁾

The onset of World War II transformed the AAA's operational context. With wartime demand for agricultural commodities soaring, supply restriction became counterproductive. The government shifted to stimulating production while maintaining price supports as income guarantees. The AAA was reorganized in 1942 into the Agricultural Adjustment Agency and subsequently merged into the Production and Marketing Administration in 1945.

The price support and allotment mechanisms established under the New Deal AAA framework persisted in modified form through the postwar decades. The Agricultural Act of 1949 established a permanent statutory foundation for price supports, and successive farm bills through the 1950s, 1960s, and beyond continued to operate within the institutional framework - county committees, allotment systems, commodity loans, parity calculations - created by the AAA legislation of the 1930s.

Whether the AAA's production controls helped raise farm incomes or primarily benefited large landowners at the expense of tenants and sharecroppers is disputed; some historians argue the program systematically displaced the most economically vulnerable agricultural workers. See AAA - Distributional Effects Viewpoint.

Whether the AAA contributed to economic recovery or, by raising food prices, reduced real incomes for urban consumers and slowed overall recovery, remains contested among economic historians. See AAA - Economic Effects Debate.

Whether the administrative structure of county committees entrenched existing racial hierarchies in southern agriculture, effectively directing benefits away from black farmers, is a matter of ongoing historical debate. See AAA - Racial Exclusion Viewpoint.

Whether Congress's enactment of the 1936 Soil Conservation Act represented a genuine conservation program or a transparent constitutional workaround with no independent policy rationale is disputed by legal historians. See AAA - Constitutionality Debate.

Whether the ever-normal granary and commodity storage provisions of the 1938 act reduced price volatility or primarily served as a mechanism for sustaining above-market prices is contested among agricultural economists. See AAA - Economic Effects Debate.
