The quality of irrigation water has been evaluated conventionally on the basis of salinity, sodicity, alkalinity and toxicity. Sodicity has been assessed through Sodium Adsorption Ratio (SAR) and alkalinity on the basis of Residual sodium Carbonate (RSC). Boron was considered as a toxic element. Due to some limitations, the parameters viz. SAR and RSC have become obsolete. The integrated effect of sodicity and alkalinity has been assessed on the basis of adjusted SAR, which accounts for precipitation and dissolution of calcium in soil water. As magnesium does not precipitate in the sol and because Mg/Ca ratio >1 tends to increase sodium hazard, a new parameter viz. adjusted Sodium to Calcium Activity Ratio (adj. SCAR) has been suggested. Whereas permissible limits for sensitive, semitolerant and tolerant crops have been suggested as 1.5, 3.0 and 5.0 dSm-1, respectively for LF 0.15 the corresponding relaxable limits stand at 3.0, 5.0 and 10.0 dSm-1, for leaching fraction of 0.3. Likewise, permissible limits (5, 10 and 20) and relaxable limits (10, 20 and 30) have been suggested for adj. SCAR, corresponding to sensitive, semi-tolerant and tolerant crops. As there has not been observed any toxicity due to boron in natural field conditions in India and because it is simultaneously amenable alongwith salinity and sodic conditions, there is no justification for giving it special importance in the evaluation of quality of irrigation waters. it should be treated simply as other trace elements.
