  • Different plants growing to the rest of the paddock.
  • Best seen in late spring.

What could this indicate?

  • Salinity caused by a salty water table less than two metres from the soil surface
  • Freshwater spring

What test can I do to confirm?

  • Soil test with reference to electrical conductivity (EC).
  • Identification of individual plant species to confirm their salt tolerance.
