Soil salinity

Dryland salinity is a major form of land degradation in Western Australia. More than one million hectares of broadacre farmland in Western Australia is estimated to be affected by dryland salinity. The Department of Primary Industries and Regional Development provides technical information to assist landholders and the community to diagnose the extent and effect of salinity, and manage the impacts. There are several practical options for increasing productivity from saline sites, and for reducing environmental damage.
