SpletSome high activity clays, such as montmorrillonite, have a shrink and swell potential. This means that the clays will shrink and crack when dry, and expand and swell when wet. With little additions of nutrients, these soils may be very productive. However, the shrink and swell potential will result in poorer drainage.
