Agriculture

 Agriculture is associated with a variety of specialized techniques, including cutting canals and extending the adaptability of land to crop cultivation through various forms of irrigation. Cultivation of crops on arable land, rearing of livestock and grazing of livestock on pasture or fallow land form the basis of agriculture. Human societies have practiced agriculture for thousands of years. Throughout history, the growth and development of agriculture has varied depending on different climates, cultures, and techniques. However, agriculture has relied on many levels of technology to cultivate the land for domesticating animals and plants and bringing it to use. Irrigation is needed to grow plants. There is also fallow cultivation. Grasslands are needed to raise animals. "Monoculture" has become widespread in developed countries as industrialized farming systems prevail.
