    en.wikipedia.org/wiki/Simcha_Blass

    The first experimental system of this type was established in 1959. In the early 1960s, Blass developed and patented this method and the new dripper was the first practical surface drip irrigation emitter. During the years 1960 to 1965 Blass developed the drip-irrigation systems and sold them inside Israel and abroad.

  3. Drip irrigation - Wikipedia

    en.wikipedia.org/wiki/Drip_irrigation

    Drip irrigation or trickle irrigation is a type of micro-irrigation system that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants, either from above the soil surface or buried below the surface.

  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. Micro-irrigation - Wikipedia

    en.wikipedia.org/wiki/Micro-irrigation

    Micro-irrigation, also called Micro-spray,localized, low-volume, low-flow, or trickle irrigation, is an irrigation method with lower water pressure and flow than a traditional sprinkler system. Low-volume irrigation is used in agriculture for row crops , orchards , and vineyards .

    V is velocity (in ft/s for US customary units, in m/s for SI units) k is a conversion factor for the unit system (k = 1.318 for US customary units, k = 0.849 for SI units) C is a roughness coefficient; R is the hydraulic radius (in ft for US customary units, in m for SI units) S is the slope of the energy line (head loss per length of pipe or h ...

  7. Irrigation management - Wikipedia

    en.wikipedia.org/wiki/Irrigation_management

    Irrigation is the artificial exploitation and distribution of water at project level aiming at application of water at field level to agricultural crops [1] in dry areas or in periods of scarce rainfall to assure or improve crop production. [2] This article discusses organizational forms and means of management of irrigation water at project level.

    That drive for profit became clear on a large-scale level in the 1970s, when a series of exposés, most notably "The Baby Killer," published by the U.K. anti-poverty charity War on Want in 1974 ...

  9. 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.
