U.S. Department of Agriculture in the context of "Food and Nutrition Service"

The Agricultural Adjustment Act (AAA) of 1933 was a United States federal law of the New Deal era designed to boost agricultural prices by reducing surpluses. The government bought livestock for slaughter and paid farmers subsidies not to plant on part of their land. The money for these subsidies was generated through an exclusive tax on companies that processed farm products. The Act created a new agency, the Agricultural Adjustment Administration, also called "AAA" (1933–1942), an agency of the U.S. Department of Agriculture, to oversee the distribution of the subsidies. The Agriculture Marketing Act, which established the Federal Farm Board in 1929, was seen as an important precursor to this act. The AAA, along with other New Deal programs, represented the federal government's first substantial effort to address economic welfare in the United States.

The National School Lunch Act (79 P.L. 396, 60 Stat. 230) is a 1946 United States federal law that created the National School Lunch Program (NSLP) to provide low-cost or free school lunch meals to qualified students through subsidies to schools. Prior to the passage of the Act, direct support of school lunches were done on the state level, or it was provided through federal aid that was not specifically designed for school lunches.

The program was established as a way to prop up food prices by absorbing farm surpluses, while at the same time providing food to school-age children. The Act was signed into law by President Harry S. Truman in 1946 and entered the federal government into schools' dietary programs on June 4, 1946. In 1999, the act's name was changed to honor Richard Russell Jr., senator from Georgia, who championed its passage.

The U.S. Department of Agriculture Administration Building, also known as the Jamie L. Whitten Building, houses the administrative offices of the U.S. Department of Agriculture in Washington, D.C. The Administration Building projects into the National Mall from the larger U.S. Department of Agriculture South Building, and is the only building on the Mall that is not intended for use by the general public. It was the first large Beaux-Arts style building in Washington and set the prototype for the later buildings of the Federal Triangle. The east and west wings were the first Federal office buildings to be built of reinforced concrete. The Whitten Building was listed on the National Register of Historic Places in 1974.

The United States has 154 protected areas known as national forests, covering 188,336,179 acres (762,169 km; 294,275 sq mi). National forests are managed by the U.S. Forest Service, an agency of the U.S. Department of Agriculture. The first national forest was established as the Yellowstone Park Timber and Land Reserve on March 30, 1891, then in the Department of the Interior. In 1897, the Organic Act provided purposes for which forest reserves could be established, including to reserve a supply of timber, protect the forest from development, and secure water supplies. With the Forest Reserve Act of 1891, the president of the United States is given the power to set aside forest reserves in the public domain. With the Transfer Act of 1905, forest reserves became part of the U.S. Department of Agriculture in the newly created U.S. Forest Service.

By 1907, President Theodore Roosevelt had more than doubled the forest-reserve acreage, and Congress responded by limiting the president's ability to proclaim new reserves. The National Forest System underwent a major reorganization in 1908, and in 1911 Congress authorized new additions to the system under the authority of the Weeks Act. The management goals provided by the Organic Act were expanded upon by the Multiple-Use Sustained-Yield Act of 1960 to include "outdoor recreation, range, timber, watershed, and wildlife and fish purposes" as well as for the establishment of wilderness areas.
