EFFECT OF SALINITY, SAR, Ca

Abstract
Effects of salinity, SAR [sodium adsorption ratio], Ca:Mg ratio in irrigation water, and soil texture were studied using 50 different solutions and 3 types of soils to predict the ESP [exchangeable sodium percentage] of soils by ESR [exchangeable sodium ratio]-SAR relationship. Adsorption of sodium slightly increased with the increase of salinity, and more with the SAR, and decreased with the Ca:Mg ratio. A lower Ca:Mg ratio enhanced soil sodicity and more so of the light-textured soil. Regression equations for ESR-SAR differed on varying soil texture and Ca:Mg ratio in the equilibrating solutions.
