Sodium Hazard of Bicarbonate Irrigation Waters1

Results of a 6-year lysimeter experiment show that the water quality value based on the precipitation index (PI) for CaCO3 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.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
