Results of a 6‐year lysimeter experiment show that the water quality value based on the precipitation index (PI) for CaCO 3 satisfactorily estimated the effect of the water on the composition of saturation extracts of soil samples, except where Na precipitation occurred. Essential conditions for Na precipitation, presumably as a zeolite, were a pH above 8.6 and time for dissolution of reactants from the soil and/or formation of the product. Tree trunk diameter growth by lemon trees ( Citrus limons ) and evapotranspiration were linearly correlated with water quality values based on PI.
