In Western Australia salinity data are commonly reported in milligrams of total soluble salts per litre of solution. Laws from solution chemistry and data on the soluble salt composition for various regions of the State were combined to derive a relationship between total soluble salt concentration (C) and osmotic potential (WO) for each region. For the south-west of Western Australia, which contains the most productive agricultural areas in the Sate, this relationship is WO = 0.075 C.
