United States farm bill
In the United States, the farm bill is the primary agricultural and food policy tool of the federal government. The comprehensive omnibus bill is passed every 5 years or so by the United States Congress and deals with both agriculture and all other affairs under the purview of the United States Department of Agriculture.
It usually makes amendments and suspensions to provisions of permanent law, reauthorizes, amends, or repeals provisions of preceding temporary agricultural acts, and puts forth new policy provisions for a limited time into the future. Beginning in 1933, farm bills have included titles on commodity programs, trade, rural development, farm credit, conservation, agricultural research, food and nutrition programs, marketing, etc.
Farm bills can be highly controversial and can impact international trade, environmental conservation, food safety, and the well-being of rural communities. The agricultural subsidy programs mandated by the farm bills are the subject of intense debate both within the U.S. and internationally.
