Here is a list of soil tests
... When the soils are wet this causes the particles to move away from each other, so the soil disperses. You have seen this in the aggregate stability test (see 1618C). Dispersion is caused by an interaction between the sodium ions and the particular type of clay. The sodium displaces other useful ion ...
