Sodic water is high in the sodium (Na+) concentration relative to concentrations of calcium (Ca2+) and magnesium (Mg2+). Sodicity of water is expressed as the Sodium Adsorption Ratio (SAR) which is: SAR = Na &#8730 [(Ca + Mg) / 2] (These values are in meq/L) The U.S. Department of Agriculture defines water with a SAR greater than 12 as sodic.
