|Most of the soils of this mapping unit have a grey to dark grey loam to sandy loam surface soil overlying a bleached light brownish grey to pale greyish brown similarly textured subsurface at about 10 to 20 cm. By about 40 cm the soil becomes variably mottled with yellow and brown colours and the texture may increase to a sandy clay loam. Mottled grey, yellow and brown light or medium clays occur between 40 and 80 cm. Most of this mapping unit can be subdivided into two components on the basis of whether or not there is a sharp texture change from a clay loam or a sandy clay loam to a medium clay within the soil profile. Component 1 soils which lack strong texture contrast, are the major components of this mapping unit. Component 2 soils have a marked texture contrast between the surface (A) horizons and subsoil (B21) horizon.|
Within the Boolarra mapping unit there may be areas of very sandy to gritty soil profiles which are described under the Morwell mapping unit. The Boolarra unit incorporates the 'Boolarra loam' soil as described by Poutsma and Turvey (1979).
