Dispersion

Dispersion causes micro-aggregates to collapse and release clay, silt and sand particles. Smaller particles move to block soil pores, which slows internal drainage and contributes to an increased risk of waterlogging. Typically, dispersion is associated with sodic soils. Dispersion is the collapse of soil aggregates into single particles, causing water to appear cloudy or milky as the clay disperses.
