In … WebThe impact of soil dispersion When a dispersive soil wets, the structure of the soil collapses. Under the impact of rain the soil slumps, soil pores collapse or are filled by dispersed clay particles. This results in a reduction in soil pore space. The consequence of this depends on whether the soil topsoil, subsoil or both are sodic.
