Dispersion (geology)

From Wikipedia, the free encyclopedia

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.

[edit] 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.

[edit] See also

• Sodication
