This report discusses legislation regarding commodities and price supports. Since 1933, Congress has required the U.S. Department of Agriculture (USDA) to administer various price and income support programs for U.S. farmers. Some standing authority for these programs is provided by three permanent laws, from 1938, 1948, and 1949. However, Congress frequently alters the basic provisions of these laws. The omnibus law now guiding farm support (through 2007) is the Farm Security and Rural Investment Act of 2002.
