{wiki=Shrink–swell_capacity}
Shrink–swell capacity refers to the ability of soil to undergo volume changes in response to fluctuations in moisture content. This property is particularly significant in clay-rich soils, which have the capacity to absorb water, expand when wet, and contract when dry. The extent to which a soil can shrink or swell is influenced by its mineral composition, texture, and structure.
