Soil salinity

Dryland salinity is a major form of land degradation. More than one million hectares of broadacre farmland in Western Australia is estimated to be currently affected by dryland salinity. The department can provide the technical information needed to assist landholders and the community to diagnose the extent and effect of salinity along with mitigation strategies. Through activities such as groundwater and soil analysis, landholders can confidently assess salinity risks and implement appropriate management responses.

    Field peas are sensitive to waterlogging and moderately sensitive to soil salinity. Soil salinity affects plant growth by reducing the roots ability to extract water from the soil.

  • Reduced emergence and smaller plants that die earlier near saline areas

    Salinity affects plant growth by reducing the root's ability to extract water from the soil. Salinity damage varies from season to season due to variations in the soil salt concentration.
