Impacts of erosion
All soils can suffer erosion but some are more vulnerable than others. Soils with dispersible subsoils, for example, are subject to serious erosion by tunnelling and gully formation.
Understanding the type of soil and how prone it is to erosion can help avoid problems in agriculture and on waterways and infrastructure.
Agriculture
Soil erosion removes valuable top soil which is the most productive part of the soil profile for agricultural purposes. The loss of this top soil results in lower yields and higher production costs.
When top soil is gone, erosion can cause rills and gullies that make the cultivation of paddocks impossible.
The impacts of erosion on cropping lands include:
reduced ability of the soil to store water and nutrients
exposure of subsoil, which often has poor physical and chemical properties
higher rates of runoff, shedding water and nutrients otherwise used for crop growth
loss of newly planted crops
deposits of silt in low-lying areas.
