  2. Water testing - Wikipedia

    en.wikipedia.org/wiki/Water_testing

    Water testing being conducted at a treatment facility in Broken Bow, Oklahoma. Water testing is a broad description for various procedures used to analyze water quality. Millions of water quality tests are carried out daily to fulfill regulatory requirements and to maintain safety. [1] Testing may be performed to evaluate:

  3. Comprehensive Assessment of Water Management in Agriculture

    en.wikipedia.org/wiki/Comprehensive_Assessment...

    successful methods of managing water in farming around the world. The assessment confirmed that agriculture consumes more water resources than any other sector. [2] A key finding was that a third of the world's population lives in water-scarce areas. More than 1.2 billion live in areas of physical water scarcity, lacking water

  4. Analysis of water chemistry - Wikipedia

    en.wikipedia.org/wiki/Analysis_of_water_chemistry

    Water chemistry analysis is often the groundwork of studies of water quality, pollution, hydrology and geothermal waters. Analytical methods routinely used can detect and measure all the natural elements and their inorganic compounds and a very wide range of organic chemical species using methods such as gas chromatography and mass spectrometry.

  5. Agricultural hydrology - Wikipedia

    en.wikipedia.org/wiki/Agricultural_hydrology

    Agricultural water balances are also used in the salt balances of irrigated lands. Further, the salt and water balances are used in agro-hydro-salinity-drainage models like Saltmod . Equally, they are used in groundwater salinity models like SahysMod which is a spatial variation of SaltMod using a polygonal network.

  6. Sodium adsorption ratio - Wikipedia

    en.wikipedia.org/wiki/Sodium_adsorption_ratio

    The sodium adsorption ratio (SAR) is an irrigation water quality parameter used in the management of sodium-affected soils.It is an indicator of the suitability of water for use in agricultural irrigation, as determined from the concentrations of the main alkaline and earth alkaline cations present in the water.

  7. Farm water - Wikipedia

    en.wikipedia.org/wiki/Farm_water

    In the US, some 80% of the fresh water withdrawn from rivers and groundwater is used to produce food and other agricultural products. [1] Farm water may include water used in the irrigation of crops or the watering of livestock. Its study is called agricultural hydrology. Water is one of the most fundamental parts of the global economy.

  8. Hard water - Wikipedia

    en.wikipedia.org/wiki/Hard_water

    The permanent hardness of water is determined by the water's concentration of cations with charges greater than or equal to 2+. Usually, the cations have a charge of 2+, i.e., they are divalent. Common cations found in hard water include Ca 2+ and Mg 2+, which frequently enter water supplies by leaching from minerals within aquifers.

  9. Residual sodium carbonate index - Wikipedia

    en.wikipedia.org/wiki/Residual_Sodium_Carbonate...

    To avoid scaling in water cooled heat exchangers, water is treated by lime and or soda ash to remove the water hardness. The following chemical reactions take place in lime soda softening process which precipitates the calcium and magnesium salts as calcium carbonate and magnesium hydroxide which have very low solubility in water.
