Agriculture

An art, science or practice of producing food, feed, fiber and other desired products through the cultivation of crops, management of the soil, and raising of livestock. Agriculture denotes activities  (i.e. tillage, fertilization, pest control, harvesting, etc.) essential to food and material production. It also includes all techniques in growing and maintaining domesticated animals (e.g. cattle, cows, goats, hogs, poultry, horses, etc.), and handling their by-products. Its prime concern is causing the land to produce more abundantly while protecting it from deterioration and misuse.
