Measuring salinity

Australian soils all contain salts in various concentrations. These salts usually occur deep in the soil profile. The amount and location of the salt store varies widely between different areas, but the amounts can be significant once mobilised. In addition to this, many groundwater bodies are naturally saline and are sometimes saltier than seawater.

Salinity in a landscape is measured to:

  • indicate how much salt is in the soil or water
  • help build a picture of salinity in waterways and catchments
  • help assess the effects of changes in land management
  • help identify where saline groundwater is likely to come to the surface.

This knowledge is critical in developing way's to manage salinity. The different methods of measuring salinity are:
