What is a normal sodium level in water?
While there is no drinking water standard for sodium, state and federal agencies recommend sodium levels in water not exceed 20 milligrams per liter (mg/L) for people on very low sodium diets and 270 mg/L for people on moderately restricted sodium diets. Most of the salt we consume comes from food.
How salty can water be for irrigation?
Most crops, including salt-sensitive crops, should accept salinity levels of up to 700 µS/cm without loss of yield. (See How salinity is measured). With salinities over 700 µS/cm, we could expect to see reduced yields from some salt-sensitive plants.
What is the salinity level for irrigation?
There will be some variation in how salinity affects the plant, depending on crop, variety, rootstock, leaching ability of the soil and also method of irrigation (spray, drip or furrow). Most crops, including salt-sensitive crops, should accept salinity levels of up to 700 µS/cm without loss of yield.
What is the acceptable sodium level in irrigation water?
Typically a SAR value below 2.0 is considered very safe for plants especially if the sodium concentration is also below 50 mg/L.
What are the acceptable levels of sodium in irrigation water?
Sodium Adsorption Ratio (SAR) Typically a SAR value below 2.0 is considered very safe for plants especially if the sodium concentration is also below 50 mg/L.
How do you analyze the salinity of water?
Salinity is the measurement of salts dissolved in a solution of water. Salinity is measured in percentage (%) or parts per thousand (ppt) and is tested either with a conductivity meter, hydrometer, or refractometer.
What is the salt concentration of irrigation water?
Salt concentration of irrigation water is measured as electrical conductivity (EC). Conventionally, water containing total dissolved salts to the extent of more than 1.5 m mhos/cm has been classified as saline. Saline waters are those which have sodium chloride as the predominant salt.
What is the measure of salinity in irrigation water?
One common measure of water salinity is electrical conductivity (EC). Basically, EC measures the capacity of a solution to transfer an electrical current between two electrodes.
