Detailed offer Description Agriculture (encompassing farming, grazing, and the tending of orchards, vineyards and timberland) is the production of food, feed, fiber and other goods by the systematic raising of plants and animals. Agri is from the Latin ager ("a field"), and culture, from the Latin cultura ("cultivation" in the strict sense of "tillage of the soil"). A literal reading of the English word yields "tillage of the soil of a field". In modern usage, the word agriculture covers all activities essential to food/feed/fiber production, including all techniques for raising and "processing" livestock. Agriculture is also short for the study of the practice of agriculture — more formally known as agricultural science. The history of agriculture is a central element of human history, as agricultural progress has been a crucial factor in worldwide socio-economic change. Wealth-building and militaristic specializations rarely seen in hunter-gatherer cultures are commonplace in agricultural and agro-industrial societies—when farmers became capable of producing food beyond the needs of their own families, others in the tribe/nation/empire were freed to devote themselves to projects other than food acquisition.
