This page explains the factors that influence the degree of dispersion in sodic soils: soil structure (aggregate stability), cation exchange capacity, calcium to magnesium ratio, exchangeable sodiu
Pumping of groundwater and disposal of saline effluent (reject water) from desalination is covered by regulations requiring owners or occupiers to notify the Commissioner of Soil and Land Conservat
Managing subsurface water can help to lower watertables and alleviate problems with waterlogging, rising salinity, and infrastructure damage.
Dispersive soils are common in the agricultural areas of Western Australia, where they occur mainly as duplex or gradational profiles.
Soil organic carbon (SOC) is inherently low in Western Australian soils – limited by climate and soil type – with some potential to increase through management.
Gully erosion is a severe form of land degradation affecting infrastructure, paddock management and property access.
Wind erosion in Western Australian agriculture is common, especially in years of late and dry growing seasons.
Farm fires will often lead to contaminated surface-water supplies: ash and soil from burnt paddocks and bushland can be blown or washed into farm dams and provide nutrients for bacteria and algae.
Land conservation district committees (LCDCs) are statutory committees appointed by the Commissioner of Soil and Land Conservation in Western Australia, to administer land conservation districts in
More than 1 million hectares of previously productive land in South West Western Australia (SW WA) is now severely affected by dryland salinity.
