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
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
Soil organic carbon is a measureable component of soil organic matter.
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.
Wind erosion in Western Australian agriculture is common, especially in years of late and dry growing seasons.
Following a fire that removes paddock ground cover, the risk of water erosion is greatly increased.
The Department of Primary Industries and Regional Development works with the land-use planning system to ensure that land and water resources are available for agriculture and food businesses to ex
The Department of Primary Industries and Regional Development provides up-to-date information about the coming season and its potential impacts on cropping and agriculture.
The table below provides suggested maximum velocities of surface water flow on various soils. This information can be used when designing surface water management structures.
