Sodosol (Yellow) and landscape AU
Soil profile: A Hypercalcic, Mottled-Subnatric, Yellow Sodosol. Original notes and photos provided by the State of Victoria (Agriculture Victoria) with revision. Profile described by Mark Imhof and David Rees (April 2005).
Landscape: Interdune depression (stubble paddock not tilled since 1991). These soils formed in Quaternary (Woorinen Formation) aeolian deposits on a 1% north-east facing slope.
Sodosols have a strong texture contrast between surface (A) horizons and subsoil (B) horizons and the subsoil horizons are sodic. Using the Australian Soil Classification, Sodosols can be grouped further (Suborder) based on the colour of the upper 20 cm of the subsoil i.e. red, brown, yellow, grey and black. These can be further differentiated based on subsoil characteristics (Great Groups) such as the level of sodicity (in the upper B horizon) and the presence of carbonate or lime (Subgroup).

In soil taxonomy, these soils are commonly Alfisols or Aridisols. For more information about Soil Taxonomy, visit;
