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.
