|These texture contrast soils are found on Palaeogene sediments around the foothills of the Otway Range and have many of the characteristics of the non-sodic soils on Palaeogene sediments, but have strongly acidic upper subsoils, due mainly to greater leaching. An organic fine sandy clay loam (about 15 to 35 cm) clearly overlies a bleached massive sandy loam subsurface horizon often to a depth of 50 cm to 100 cm, abruptly overlying a coarse to medium strongly structured grey mottled (orange and yellow) light to medium clay which grades at about 100 cm or more into a sandy clay and/or cemented sandstone or calcareous|
Notable characteristics include: variable depth of bleached subsurface horizon, abrupt texture contrast between surface soils and mottled subsoil, deep weathered profiles (sometimes vertic with depth), strongly acidic profiles, some profiles may be alkaline (calcareous) at depth depending on lithology and climate. Soil depth (total and individual horizons) is a function of topographic position and is influenced by landscape dissection and adjacent parent materials.
