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.
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
Managing subsurface water can help to lower watertables and alleviate problems with waterlogging, rising salinity, and infrastructure damage.
The aim of carbon farming is to sequester more carbon and reduce greenhouse gas emissions, as part of Australia's response to climate change.
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
Shallow relief drains are relatively cheap and easy to construct, and are effective at removing surface water from flooded or ponding land.
Natural or constructed grassed waterways can be used to safely move surface water across the landscape, handle water flow into and out of dams, the end of grade banks and other surface water dispos
Soil organic carbon is a measureable component of soil organic matter.
Gully erosion is a severe form of land degradation affecting infrastructure, paddock management and property access.
