Frequently Asked Questions

What is saline water and why is it defined as saline?

Frequently Asked Questions, Saline and/or Sodic Water and So...
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. See similar questions...

What is saline water and why is it considered saline?

Coal Bed Methane Frequently Asked Questions
Saline water has a relatively high concentration of dissolved salts. Salt is not just "salt" as we know it - sodium chloride (NaCl) - but can be dissolved calcium (Ca2+), magnesium (Mg2+) sulfate (S042-), bicarbonate (HC03-) and Boron (B). See similar questions...

Are some soils more sensitive than others to saline and/or sodic water?

Coal Bed Methane Frequently Asked Questions
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...

What are the risks with saline (salt-water) implants?

Breast-Augmentation : Frequently Asked Questions
In the unlikely event that a saline implant becomes ruptured or leaks, the salt- water is harmlessly absorbed by the body. See similar questions...

Is it well-defined?

Larch Frequently Asked 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...

Can a water source be both saline and sodic?

Frequently Asked Questions, Saline and/or Sodic Water and So...
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...

How is normal water storage defined?

Provincial Water Data Reports - Alberta Environment
Normal water storage is based on the quartile system using historically recorded values for the given time period. Storage values that fall between the upper and lower quartiles of historically recorded levels for the perod are considered normal. Storage values that fall below the lower quartile are considered below-normal, similarily storage values that are above the upper quartile are considered above-normal. See similar questions...

How is recycled water defined?

Melbourne Water : Water Recycling : Links and FAQS : Links a...
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...

What causes a water source to be saline or sodic?

Frequently Asked Questions, Saline and/or Sodic Water and So...
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. See similar questions...

How does saline water affect alfalfa growth?

Frequently Asked Questions, Saline and/or Sodic Water and So...
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...

How can one safely use saline water for irrigation?

Frequently Asked Questions, Saline and/or Sodic Water and So...
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...

Can anything be added to saline and/or sodic water to "treat" (or clean) the water?

Frequently Asked Questions, Saline and/or Sodic Water and So...
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...

What is a sodic water and why is it defined as sodic?

Frequently Asked Questions, Saline and/or Sodic Water and So...
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...

What are the common problems or difficulties with the use of saline water for irrigation?

Frequently Asked Questions, Saline and/or Sodic Water and So...
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...

How long does it take for the effects of irrigation with saline water to be evident in the soil?

Frequently Asked Questions, Saline and/or Sodic Water and So...
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...

What is the tolerance of common Montana crop and forage species to saline irrigation water?

Frequently Asked Questions, Saline and/or Sodic Water and So...

Why isn't the CraigCat defined as a PWC (personal water craft)?

Under NSW legislation the definition of a PWC states that the driver must either stand, kneel, or sit astride the vessel. See similar questions...

How can I get silicone gel instead of saline?

Breast-Augmentation : Frequently Asked Questions
If you are a first time cosmetic breast augmentation patient, the only implant option offered to you should be saline. If you are a breast reconstruction patient you can freely choose silicone implants. Also, if you already have saline breast implants and elect to switch out your implant you may be eligible for silicone at that time. See similar questions...

Can I have saline added to my implants after the surgery?

Breast Implants FAQ
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. See similar questions...

What is a saline seep?

Frequently Asked Questions, Saline and/or Sodic Water and So...
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...
