This is evident from weak, mostly brownish discolouration and/or structure formation in the soil profile.
Cambisols are developed in medium and fine-textured materials derived from a wide range of rocks, mostly in alluvial, colluvial and aeolian deposits.
Most of these soils make good agricultural land and are intensively used.
Cambisols cover an estimated 15 million square kilometres worldwide.
They are well represented in temperate and boreal regions that were under the influence of glaciation during the Pleistocene, partly because the soil's parent material is still young, but also because soil formation is comparatively slow in the cool, northern regions.
