Agriculture

n. raising of crops and livestock

Agriculture (from Agri Latin for 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".) is the production of food, feed, fiber and other goods by the systematic raising of domesticated plants and animals. 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.
