Soil salinity refers to the presence of dissolved salts within the soil profile and water table. Changes in land use and management can cause the water table to rise and result in the accumulation of salts within the soil root zone and soil surface.
Increasing soil salinity directly affects the chemical nature of the soil, subsequently affecting the biological relationships and physical structure. In turn this leads to degradation issues such as compaction, desertification and exposure to erosion.
The rate and extent of dryland salinity within some areas of the SA Murray-Darling Basin region has increased dramatically in recent years.
