The following quotes are from: Isbell, R.F. 1998. The Australian Soil Classification. CSIRO Publishing, PO Box 1139 (150 Oxford Street), Collingwood, VIC, 3066, Australia) Dermosol order Concept "Soils with structured B2 horizons and lacking strong texture contrast between A and B horizons. Although there is some diversity within the order, it brings together a range of soils with some important properties in common." DEFINITION "Soils other than Vertosols, Hydrosols, Calcarosols and Ferrosols which: (i) Have B2 horizons with structure more developed than weak throughout the major part of the horizon; and (ii) Do not have clear or abrupt textural B horizons." There are 5 suborders of Dermosols based on: "The dominant colour class in the major part of the upper 0.5 m of the B2 horizon (or the major part of the entire B2 horizon if it is less than 0.5 m thick)" The 5 suborders are Red, Brown, Yellow, Grey and Black. The color definition for Black is: "The dominant colour (moist) for all hues has a value of 3 or less and a chroma of 2 or less".
