Reassessing irrigation water quality guidelines for sodicity hazard
Abstract
Current irrigation water quality guidelines for sodicity hazard, in use since the 1980s, are based on assessments of salinity (Electrical conductivity, EC) and sodicity (Sodium Adsorption Ratio, SAR), where SAR considers the positive effects of calcium (Ca) and magnesium (Mg) against the adverse effects of sodium (Na) on soil permeability. Recent research and practice, however, have provided ample evidence for negative effects of both potassium …
