Sodium adsorption ratio is a measure of the amount of
sodium (Na) relative to calcium (Ca) and magnesium (Mg) in the water extract. Which of the following SAR range is moderately safe for the crops?ÂSolution
The SAR range considered moderately safe for most crops generally falls between:Â 3 to 9 This range suggests a moderate level of sodium compared to calcium and magnesium, reducing the risk of soil dispersion which can affect soil structure and permeability. It is important for farmers and agricultural managers to monitor SAR values to ensure water quality is maintained within safe limits for optimal crop health and yield.
