Description
Ap
0–5 Dark brown (10YR3/3); sandy loam, clear boundary to:

A2
20-35 Brown (10YR4/3 moist), bleached (2.5Y6/3 dry) with very pale brown to yellow diffuse mottling; loamy sand; massive structure when dry, very firm dry consistence ; pH 6.6; sharp boundary to:

B21t
50-70 Dark grey (10YR4/1 moist and dry) with clay coatings on well developed very coarse (100–300 mm) prismatic structure having strong brown (10YR4/6) sandy interiors; parting to smaller prismatic structure and coarse angular blocky/polyhedral structure; strong consistence (dry); large slickensides at base of prisms; pH 8.1; clear boundary to:

B22(ss)t
95-110 Reddish brown (5YR4/4 moist and dry) clay surrounding light olive brown (2.5Y5/3) sandy clay matrix, polyhedral structure with many lenticular clay peds; slickensides; pH 9.0; diffuse boundary to:

B23t
Profile becoming redder and sandier with depth (Moorabool Viaduct sediments).

Management considerations
‘Spewy’ topsoil and sharp boundary to coarsely structured sodic clay subsoil render this soil very prone to waterlogging. The soil is situated at the upper end (initiation) of a drainage line carrying excess water from the basalt plain to the Moorabool River. This is highly erodible soil which should have permanent vegetation cover to protect river water quality. See also site SW100 for an associated soil type —these two sites are only 45 metres apart.
