Irrigation water quality
Ayers (1977) proposed the following guidelines (in the following table) by considering the four areas: water salinity (ECw), soil permeability, plant toxicity effect, and other miscellaneous. The guidelines are flexible and should be modified in accord with local experience, special conditions of crop, soil, climate, method of irrigation and specific agronomic practices used in the area.
