Center-pivot irrigation (sometimes called central pivot irrigation), also called water-wheel and circle irrigation, is a method of crop irrigation in which equipment rotates around a pivot and crops are watered with sprinklers.

  3. Environmental impact of irrigation - Wikipedia

    en.wikipedia.org/wiki/Environmental_impact_of...

    The lower the irrigation efficiency, the higher the losses. Although reasonably high irrigation efficiencies of 70% or more (i.e., losses of 30% or less) can occur with sophisticated techniques like sprinkler irrigation and drip irrigation or by well-managed surface irrigation, in practice the losses are commonly in the order of 40% to 60% ...

  4. Irrigation - Wikipedia

    en.wikipedia.org/wiki/Irrigation

    Micro-irrigation, sometimes called localized irrigation, low volume irrigation, or trickle irrigation is a system where water is distributed under low pressure through a piped network, in a pre-determined pattern, and applied as a small discharge to each plant or adjacent to it. Traditional drip irrigation use individual emitters, subsurface ...

  5. Irrigation statistics - Wikipedia

    en.wikipedia.org/wiki/Irrigation_statistics

    94% of the application methods of irrigation water at field level is of the category surface irrigation, [1] whereby the water is spread over the field by gravity.. Of the remaining 6%, the majority is irrigated by methods requiring energy, expensive hydraulic pressure techniques and pipe systems like sprinkler irrigation and drip irrigation, for the major part in the USA.

  6. Water scarcity in the United States - Wikipedia

    en.wikipedia.org/wiki/Water_scarcity_in_the...

    Water scarcity impacts agricultural productivity, creating immense challenges for farmers and food production. With limited water resources, farmers struggle to irrigate their crops adequately, insufficient irrigation affects plant growth, leading to reduced yields of water-intensive crops such as rice, soybeans, wheat, sugarcane, and cotton, most of which are breadbasket staples.

    The old Sardar canal project in the state of Gujarat, India, was designed with an irrigation intensity of 32%, but at the upstream part the delivery was at an intensity of 42% (i.e. 131% of the design norm) and at the downstream end it was only 19% (i.e. 59% of the norm), although the project aimed at protective irrigation with equal rights for ...
