Irrigation water suitability, soil, salinity, crops, the farm and food safety.
The Sodium Adsorption Ratio (SAR) and electrical conductivity (EC) are the two primary indices for assessing irrigation water suitability. This article explains how they are calculated, how they interact to affect soil permeability and crop yield, and how the Ayers-Westcot framework translates measurements into practical irrigation restrictions.
