An identified source of irrigation water has ion concentrations of Na...
< b="" />Explanation:< />
The SAR (Sodium Adsorption Ratio) is a measurement used to determine the suitability of irrigation water for agricultural purposes. It is calculated based on the concentration of sodium ions (Na+), calcium ions (Ca2+), and magnesium ions (Mg2+) in the water.
To calculate the SAR, the following formula is used:
SAR = (Na+ / (Ca2+ + Mg2+))^0.5
Given that the concentrations of Na+, Ca2+, and Mg2+ in the irrigation water are 28, 12, and 20 milliequivalents per litre (meq/L) respectively, we can calculate the SAR as follows:
SAR = (28 / (12 + 20))^0.5
= (28 / 32)^0.5
= (0.875)^0.5
≈ 0.936
< b="" />Interpretation:< />
The SAR of the irrigation water is approximately 0.936.
< b="" />Comparison:< />
The SAR value indicates the relative concentration of sodium ions compared to calcium and magnesium ions in the water. A higher SAR value indicates a higher concentration of sodium ions, which can have negative effects on soil structure and plant growth.
In general, a SAR value of less than 10 is considered suitable for most crops. Therefore, the SAR value of 0.936 falls within the acceptable range, suggesting that the irrigation water is suitable for agricultural use.
< b="" />Conclusion:< />
The SAR of the irrigation water is approximately 0.936, which falls within the acceptable range for agricultural use.
