To irrigate land means to supply it with water in order to help crops grow. None of the water from Lake Powell is used to irrigate the area. + irrigation ir·ri·ga·tion The agricultural land is hilly and the irrigation poor
The application of water to crops, lawns, and gardens by arteficial means to supplement natural precipitation Water can be applied by spreading, sprinkling, or dripping (Rice (1991))
Artificial supply of water to land, to maintain or increase yields of food crops, a critical element of modern agriculture. Irrigation can compensate for the naturally variable rate and volume of rain. Water is pumped from natural ponds, lakes, streams, and wells; basin systems and dams hold back larger streams and annual floods. Below the dam, gates to concrete-lined canals are opened, conveying the water over the land through gravity flow. More elaborate, expensive canals flow from huge constructed reservoirs, which hold a year-round water supply. Today portable irrigation systems of lightweight aluminum pipe are in wide use. Drip irrigation, a newer method, uses narrow tubing to supply water directly to the base of each plant. Agricultural irrigation, water towers, and machines invented to lift and distribute water are ancient innovations. Early Egyptians were irrigating with Nile River water by 5000 BC, and such other ancient civilizations as Babylon and China seem to have developed largely as a result of irrigation-based agriculture
Manner in which water is artificially applied to crop land e g Sprinkler irrigation - water is sprayed over the soil surface using a pressurized system
watering of land by artificial methods, such as canals or sprinkler systems, providing water for crops in areas that have long periods of little or no rainfall
Controlled, artificial application of water to assist in the growth of crops and pastures, or to maintain vegetative growth in recreational lands such as parks and golf courses
The application of water to a grassed area Small areas can be irrigated by using a hose pipe and attachment Larger areas, especially high quality sports turf ones, will have fixed automatic pop-up sprinklers
(medicine) cleaning a wound or body organ by flushing or washing out with water or a medicated solution supplying dry land with water by means of ditches etc
Applying water (or wastewater) to land areas to supply the water (and sometimes nutrient) needs of plants Techniques for irrigating include furrow irrigation, sprinkler irrigation, trickle (or drip) irrigation, and flooding About 51 million acres of land are irrigated in the United States More acres of corn are irrigated than any other crop, but only about 15% of the harvested acres In contrast, irrigation is used for 100% of rice, 81% of orchards, 64% of vegetables, and 36% of cotton About 40% of freshwater withdrawals in the nation are for irrigation, making agriculture the single largest user of water Nearly 90% of all irrigation water withdrawals are in the western states, where in some areas competition for available supplies among uses, including base stream flow, has become controversial Consumptive use as a percent of withdrawals is about 61% for irrigation
A system of pipes, and drainage points that direct rain water, and runoff to a collection area or percolation field to prevent washing out your home, or creating standing water
water that reaches the lower end of a field; excess surface water draining especially from a field under cultivation Tail water is not necessarily lost; it can be collected and reused on the same or adjacent fields
The application of water to offset arid conditions, such as for the purpose of sustaining plant life or promoting growth, and to facilitate crop production
The act or process of irrigating, or the state of being irrigated; especially, the operation of causing water to flow over lands, for nourishing plants
Water that is especially furnished to help provide and sustain the life of growing plants It comes from ditches It is sometimes treated with herbicides and pesticides to prevent the growth of weeds and the development of bugs in a lawn and a garden
