Water is classified as "saline" when it becomes a risk for growth and yield of crops. Saline water has a relatively high concentration of dissolved salts (cations and anions). Salt is not just "salt" as we know it - sodium chloride (NaCl) - but can be dissolved calcium (Ca2+), magnesium (Mg2+), sulfate (SO42-), bicarbonate (HCO3-), Boron (B), and other compounds.

Yes. Irrigation water that is suitable for one soil may not be for another. Use of saline and/or sodic water for irrigation can be risky business on soils predominated by silt or clay. Just 1 acre-foot of moderately saline irrigation water (EC = 3 dS/m - the upper end of suitability for irrigation water) will introduce 1.8 tons of salt to an acre of land. Soluble salts do not leach as readily through fine textured soils as through sandy soils. See similar questions...

a help in avoiding this problem, you can use a generated freely by clause in the most recent versions of LSL. The use of a generated freely by clause makes it clear that the reader does not have to be concerned about ill-defined structural inductions. Another pitfall in LSL is to assert that all values of some freely-generated type satisfy some nontrivial property. An example is the trait given below. See similar questions...

Water can be both saline and sodic, or saline-sodic. If water has an EC greater than 4 (2 for horticulture) and a SAR greater than 12, it is considered saline-sodic. See similar questions...

Recycled water is defined as water that has been treated to a 'fit for purpose' standard for a specific application. The following water classes can all be used to replace potable water and, if used in an EPA-approved fit-for-purpose application, can be classified as recycled water: See similar questions...

Water can naturally become saline or sodic by coming into contact with soil or geologic material that is high in salts. Upon contact, salts dissolve into the water, raising the EC and/or the SAR of the water. Water can also become saline when evaporation concentrates naturally occurring salts.

Saline water reduces plant growth to varying degrees, with grass and grain crops generally showing less sensitivity and field crops being most sensitive. Aside from biomass reduction, salinity can have additional effects on plants. For example, in a study by Bauder et al., both inoculated and non-inoculated alfalfa were grown with irrigation waters of progressively higher salinity levels (Figure 1). See similar questions...

Modestly saline water can often be used successfully in the right soil x crop combination without hazardous long-term effects on the crops or soils. However, certain conditions need to be met: salinity of either the irrigation water or soil solution increases (with prolonged crop water use and through the irrigation season), the volume of irrigation water applied should be progressively increased. See similar questions...

There are no amendments, chemicals, or additives available commercially that can be added to saline water to make the salt go away. Dilution with a non-saline water or salt precipitation with an evaporation process which leaves the salt behind and traps the evaporated water can be used. Dilution of saline irrigation water is only possible if there is a source of non-saline water with which to dilute the saline water. See similar questions...

Sodic water is high in sodium (Na+) concentration relative to concentrations of calcium (Ca2+) and magnesium (Mg2+). The sodicity of water is expressed as the sodium adsorption ratio (SAR), See similar questions...

Saline water reduces plant growth, making irrigation with it risky if not managed properly. With time, salts carried in saline water may accumulate in the root zone to concentrations high enough to affect crop growth by reducing availability of water. Just 1 acre-foot of irrigation water of moderately saline quality (EC = 2 dS/m - the upper end of suitability for irrigation water) will introduce 1.8 tons of salt per acre of land. See similar questions...

Soils do not usually become excessively saline from use of saline water in a single irrigation season. It may even take several irrigation seasons to affect the level of salt in the soil solution. The maximum soil salinity in the root zone that results from continuous irrigation with saline water does not occur when salty water is used only a fraction of the time. See similar questions...

Most breast implants will allow for additional saline to be added (or removed) after surgery. This is a simple office procedure, and can be done under local anesthetic. The price for this varies from surgeon to surgeon, so you will need to ask your doctor what his/her fee is. However, the Mentor High Profile saline breast implants, Mentor Spectrum Expandable, and Mentor Becker Expandable breast implants cannot have saline added or removed once the fill port is taken out.

If water is introduced to an upland site in a watershed and is not removed by plant uptake, it could move below the root zone, travel down slope, and surface at a low spot in the watershed. In some geologic formations (especially in soils formed from glacial till or stratified marine deposits) water percolating through the soil dissolves salt from the soil. See similar questions...

A defined network plan is the term used in Wisconsin insurance law to refer to any health benefit plan that creates incentives for its enrollees to use network providers. Some defined network plans will provide coverage only if the enrollee uses network providers and other plans will pay a larger portion of the charges if the enrollee uses network providers. HMOs and preferred provider plans are examples of defined network plans. Some people refer to these plans as managed care plans. See similar questions...

The size class for cars is based on interior passenger and cargo volumes as described below. The size class for trucks is defined by the gross vehicle weight rating (GVWR), which is the weight of the vehicle and its carrying capacity. Fuel economy regulations do not apply to heavy-duty vehicles, so they are not tested. See Which Vehicles Are Tested for more information on these vehicles. See similar questions...

athlete usually has proximal weakness and no triceps. Functionally they move their chair with elbows out and limited wheel contact. athlete has stronger muscles proximally, a more balanced shoulder, and can have limited triceps function. The 1.0 player has longer wheel contact, with elbows closer to the athlete's body. class was created to handle those players who fall between the 1.0 and 2.0 classes or those players with stronger but not normal triceps in both arms.
