Black cotton soil (also known as Regur soil) is another type of cohesive soil. It is highly expansive and exhibits plasticity when wet, similar to clay. Black cotton soil has a high clay content, which gives it the cohesive properties of clays. It can swell when it absorbs water and shrink when it dries, making it quite reactive to moisture changes.

So, both Clay and Black cotton soil are cohesive soils.
