Dispersion (geology)
Dispersion occurs when a soil is sodic. When a sodic soil is wetted the clay particles are forced apart. This is generally a major cause of erosion.
Prevention of dispersion
Preventing dispersion can be done by:
- re-vegetating the area
- preventing the soil from becoming sodic though management of salinity
- careful management of soils on slopes, such as avoiding clearing slopes.
