Dispersion (geology)

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.
