Abstract

Prediction of sodium adsorption ratio using available soil properties and simple empirical models have become particularly urgent to reduce the time and cost of some complex soil properties. The aim of this study is to estimate the sodium adsorption ratio (SAR) from soil electrical conductivity (EC), soluble calcium (Ca++) and magnesium (Mg++) to this end, a new equation was modified from soil SAR equation (MSAR).
