Sar index water
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. An adjusted SAR adj value may be calculated for water with high carbonate and bicarbonate content. For example, when the irrigation water contains free lime (calcareous soil). High carbonate and bicarbonate present in water will cause the precipitation of the calcium and magnesium and increase the relative concentration of sodium increasing the SAR index. Adjusted SAR, Salinity, Sodium hazard, Water quality. he sodium adsorption ratio (SAR) is commonly used as an index for evaluating the sodium hazard associated with an irrigation water supply. The SAR is defined as the square root of the ratio of the sodium (Na) to calcium + magnesium (Ca + Mg), i.e.: Ca Mg Na SAR + = (1a) Adjusted SAR (cell C27) uses the bicarbonate to calcium ratio (HCO 3 /Ca) to account for calcium precipitation in the soil as lime. Adjusted SAR will be either the same or larger than SAR. For water with SAR < 3, there should be no restrictions on use or plant growth. Problems increase when SAR is between 3 and 9. A useful index for predicting this tendency is the Sodium Adsorption Ratio (SAR). An SAR less than 8 (mmoles l −1) 0.5 is considered to be a ‘low sodium’ water class, i.e. the use of the irrigation water with SAR less than 8 is rated as being safe with regard to causing sodicity. That said, the prolonged use of class 8 SAR water for Turfgrass Diagnostic Laboratory Sample Submission Form. Roadside Vegetation Management. Links Bicarbonate hazard of irrigation water: High carbonate (CO 3 =) and bicarbonate (HCO 3-) increases SAR index (around >3-4mEq/L or >180-240mg/L). Let's explain why: Bicarbonate and carbonate ions combined with calcium or magnesium will precipitate as calcium carbonate

Specific Absorption Rate (SAR) is a measure of the rate at which energy is absorbed by the human body when exposed to a radio frequency (RF) electromagnetic field. It can also refer to absorption of other forms of energy by tissue, including ultrasound.
