Carbon dioxide dissolves in water, including water in soil solution, to form carbonic acid. Carbonic acid breaks down into carbon dioxide. 8. The two most important measures for determining irrigation water quality are: 1. The total amount of dissolved salts in the water. 2. The amount of sodium (Na) in the water compared to calcium (Ca) plus magnesium (Mg). The total dissolved salt content is estimated by measuring how well the water conducts … See more The most damaging effects of poor-quality irrigation water are excessive accumulation of soluble salts and/or sodium in soil.
