Abstract:
This chapter reviews the importance of swelling, dispersion, and slaking, and examines the effect of sodicity and electrolyte concentration on swelling, dispersion, and slaking and the consequent changes in soil hydraulic properties. A soil in which the primary sand, silt, and clay particles are not bound together into larger units is rare. These structural units are known as aggregates or peds and they are described according to their size, shape, and distinction in the soil profile. They are formed when clay particles interact with each other and with silt- and sand-size particles. Harris et al. (1966) categorize the many possible interactions into four types: (1) Clay-clay interactions, in which a cation forms the linkage between negatively-charged clay faces; (2) clay-edge to clay-face interactions; (3) clay-edge or clay-face to clay-edge or clay-face interactions, in which a polymer forms the linkage; and (4) interactions among uncharged particles linked by silt and organic or inorganic colloids. This basic model continues to be studied, and an extensive literature on soil structure now exists.
