Frequently Asked 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.

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).

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.

How much water can I expect my irrigation system to use?

Department Frequently Asked Questions
Depending on the pressure from the County's water line an irrigation system can use 6 to 9 gallons of water per minute per sprinkler head. As an example: let us assume that one irrigates three (3) days per week for two (2) hours per day at an average 7.5 gallons per minute.

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.

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.

Can I use the discharged water for irrigation purposes?

Hydro-Guard FAQ
There are many reports of atmospheric-discharge units feeding shrubbery and other landscaping around the installation site. Additionally, a number of Hydro-Guard® municipalities direct discharged water into culverts or retention ponds for use in feeding irrigation systems. Due to the controlled discharge offered by a number of the Hydro-Guard® Units, any one of these may be well suited to this purpose. Please feel free to contact us concerning your specific application.

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

So what about irrigation or supplemental water – can it still be environmentally friendly?

FAQ's
Yes. You can install a traditional active irrigation system or a solar powered system. Pair this with a recycled rainwater collection system, harvested in cisterns at roof deck or at ground level, and you’ve got the ideal self-sustainable answer to supplemental water and how to power it.

Where does irrigation water come from and how is it applied to the land?

Ground Water - Introduction - FAQs
Both ground water and surface water are used for irrigation. In 1990, about 51,000 million gallons per day were withdrawn from the ground for irrigation, whereas about 85,500 million gallons per day was taken from surface-water sources. A small amount of reclaimed wastewater coming from sewage-treatment plants, about 660 million gallons per day was used for irrigation. The USGS keeps records on the types of irrigation systems used in the United States.

What makes ALKALOL different from other nasal irrigation products, like saline rinses?

FAQ - The Alkalol Company
Unlike some nasal irrigation products, ALKALOL contains no antihistamine, preservatives, or other chemicals that can irritate and damage tender mucous membranes in the nasal passages. Instead, since it was originally formulated in 1896, ALKALOL has been made with soothing natural ingredients, including eucalyptol, thymol, menthol, camphor, and oils of wintergreen, spearmint, pine and cinnamon.

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.

In a dry climate, which water irrigation process do you use and why?

The Bonny Group - FAQ
Water reservoirs, dams and regulating ponds collect water during the summer to be used for irrigation during the drier winter months. We were also the first company to use desalination by reverse osmosis for agricultural purposes. Thanks to these methods we can always guarantee that our plants have enough water and, at the same time, we don't misuse this very limited resource.

What are some of the water-conserving irrigation methods?

FAQ-general
There are various irrigation methods that can help in water conserving techniques. We can assess the need of irrigation by testing the soil-moisture of the soil. Add organic matter to the soil to improve structure, which also improves the water holding capacity of the soil. Preparation of soil at deep depths, which helps plants to get established in the soil sooner and increases the interval of irrigation time. Mulching deters the growth of weeds, which can use a lot of water.

When we do the colonic irrigation where does the water go?

Dharma Healing Center Of Samui, fasting, holistic weight los...
The water goes into the large intestines the opposite direction that stools are eliminated. In a colonic the water will go throughout the whole large intestines. It stops at the ileocecal valve, a one way valve that will not open into the small intestines.

Why is the irrigation water dirty?

Farmers Irrigation District, Hood River, Oregon
Farmers Irrigation District screens the water to 1/8” or 1/32” on the pressurized systems. Open ditch systems experience fluctuations, causing the water to rise and lower several times per day, stirring up sediment. Ditches are also subject to annual cleanouts and county grass cutting. During periods of dirty water we recommend cleaning your filter several times per day or shutting off your system until the evening.

How much water is used in lawn irrigation?

UAWCD - FAQ
Roughly half of municipal water deliveries in the summer are for landscape irrigation, particularly Kentucky blue grass.

Who should I call if I see irrigation water running onto the streets?

SRP: Frequently asked questions
Please call SRP's Irrigation Customer Service Office at (602) 236-3333. Reporting irrigation water running onto the streets allows us opportunities to contact users involved and/or cut off the water until we determine what is causing the flooding.

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

Frequently Asked Questions, Saline and/or Sodic Water and So...
Elevated sodium and chloride concentrations in water can harm some woody plants due to direct toxicity as ions are taken up by the root cells or applied directly to the leaves. Either way, ions can accumulate in the leaves, causing burn along the outer leaf edges. In addition, sodium can indirectly affect crop growth by causing calcium, potassium, and magnesium deficiencies or by adversely affecting soil physical properties.
