Anderson has one or more farms. These are areas of land devoted to agriculture and related occupations. The sum total of the land and the buildings that stand on it are known as the farmstead. The crops grown can be either foodcrops or cash crops. While food production is the basic function of farming, cash crops are used in production of fabric, animal feed and increasingly significantly, fuel. Major crops include corn, soybean, hay, cotton, rice and wheat. Animals may also be kept for dairy or meat. The work is usually accomplished by usage of machinery, or by manual labour. Migrant labour forms the major workforce at farms. Seeds, pesticides, fertilizers, irrigation and other special factors may be needed for agriculture. Buildings in the farmstead may include a farm house (the residence of the farmer and his family), a silo for storing grain, and a barn for the livestock.
