Changes in soil properties caused by irrigation with saline groundwater (approx. 2 dS/m) containing
excess bicarbonate were measured on Vertosols and Sodosols in the West Wimmera, Victoria, Australia. Irrigation
caused soil pH to increase, and where this had risen sufficiently (approx. 8.0), the sodium absorption ratio (SAR)
of 1 : 5 soil extracts also increased, presumably due to precipitation of calcium and magnesium carbonates. Salt
only accumulated when the SAR of 1 : 5 soil extracts was high. In contrast to previous studies, SAR of the soil
extracts was not correlated with exchangeable sodium percentage (ESP) of the exchange complex, nor with soil pH. ...
