Abstract

In the comments "Some observations with respect to sodicity hazard of irrigation waters",Dr. Van Hoorn opened a constructive discussion about the assessment of sodicity hazard of soils subjected to irrigation in arid or semi arid areas (Van Hoorn, 2003). The following are three concepts usually used for the aforementioned assessment, which are reminded in his comment on our article: "the sodium adsorption ratio (SAR) = $Na/((Ca + Mg)/2)^{1/2}$ in eq. $L^{-1}$, (Richards, 1954);" the adjusted SAR $(SAR_{adj})$= SAR (1+ (8.4-pHc)), (Suarez, 1981;Ayers and Westcot,1985);"the residual sodium carbonate (RSC) = alkalinity-Ca-Mg in eq. $L^{-1}$ (Eaton, 1950;Richards, 1954).
