Soil crust A transient soil-surface layer, ranging in thickness from a few millimeters to a few centimeters,
that is either denser, structurally different or more cemented than the material immediately beneath it,
resulting in greater soil strength when dry as measured by penetration resistance or other indices of soil
strength.}
