Farm

A farm is an area of land, or, for aquaculture, lake, river or sea, including various structures, devoted primarily to the practice of producing and managing food (produce, grains, or livestock), fibres and, increasingly, fuel. It is the basic production facility in food production. Farms may be owned and operated by a single individual, family, community, corporation or a company. A farm can be a holding of any size from a fraction of a hectare to several thousand hectares.
