definition of agriculture
Answers
Answer:
1) Agriculture is the science and art of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago.
2)Agriculture describes the practice of growing crops or raising animals. Someone who works as a farmer is in the agriculture industry.
Answer:
the science or practice of farming, including cultivation of the soil for the growing of crops and the rearing of animals to provide food, wool, and other products. Agriculture is the process of growing plants for raw materials for industries,medicinal purpose or even for utility as food.Animal husbandry also comes under agriculture.
Explanation:
Agriculture is the process of producing food, feed, fiber and many other desired products by the cultivation of certain plants and the raising of domesticated animals (livestock).
The practice of agriculture is also known as "farming", while scientists, inventors and others devoted to improving farming methods and implements are also said to be engaged in agriculture.
Subsistence farming, who farms a small area with limited resource inputs, and produces only enough food to meet the needs of his/her family.
At the other end is commercial intensive agriculture, including industrial agriculture.
Such farming involves large fields and/or numbers of animals, large resource inputs (pesticides, fertilizers, etc.), and a high level of mechanization.
These operations generally attempt to maximize financial income from grain, produce, or livestock.
Modern agriculture extends well beyond the traditional production of food for humans and animal feeds.
Other agricultural production goods include timber, fertilizers, animal hides, leather, industrial chemicals (starch, sugar, alcohols and resins), fibers (cotton, wool, hemp, silk and flax), fuels (methane from biomass, ethanol, biodiesel), cut flowers, ornamental and nursery plants, tropical fish and birds for the pet trade, and both legal and illegal drugs (biopharmaceuticals, tobacco, marijuana, opium, cocaine).
The 20th Century saw massive changes in agricultural practice, particularly in agricultural chemistry.
Agricultural chemistry includes the application of chemical fertilizer,chemical insecticides, and chemical fungicides, soil makeup, analysis of agricultural products, and nutritional needs of farm animals.
Beginning in the Western world, the green revolution spread many of these changes to farms throughout the world, with varying success.
Other recent changes in agriculture include hydroponics, plant breeding, hybridization, gene manipulation, better management of soil nutrients, and improved weed control.
Genetic engineering has yielded crops which have capabilities beyond those of naturally occuring plants, such as higher yields and disease resistance.
Modified seeds germinate faster, and thus can be grown in an extended growing area.
Genetic engineering of plants has proven controversial, particularly in the case of herbicide-resistant plants.
