Australian Soil Classification: Epicalcareous - Epihypersodic, Massive, Red VERTOSOL (moderate profile depth)
General Landscape Description: Near level plain.
Site Description: Broad flat ridge with easterly aspect slope <1%.
Geology: Quaternary Basalt.
Soil Profile Morphology:
|Ap||0-12 cm||Brown (7.5YR4/3 moist); hardsetting surface condition; light clay; apedal structure; contains shelly material including intact shells; pH 7.9; clear and smooth change to:|
SW103 Profile - Note: Surface stripped from soil profile.
|B21t||12-30 cm||Dark reddish brown (5YR3/3 moist); medium heavy clay; fine prismatic structure, parting to fine polyhedral; pH 9; clear and smooth change to:|
|B22ss||30-60/75 cm||Dusky red (2.5YR3/3), becoming brown (7.5YR4/3) at depth; medium heavy clay; prominent slickensides (up to 30 cm across); pH 9.5; clear and wavy change to:|
|B23k||60/75-80/100 cm||Reddish yellow (7.5YR6/8) becoming reddish yellow (7.5YR7/8) at depth; abundant soft calcium carbonate (CaCO3); irregular change to:|
|C||80/100+ cm||Weathering vesicular soft greenish basalt; tongues of calcium carbonate (CaCO3) from B23k above; some biological activity present (ant nests).|
(at 40-55 cm)
Very Strongly Alkaline
|1 Strong dispersion after remoulding.|
|The surface is slightly alkaline. The subsoil is strongly alkaline becoming very strongly alkaline at depth.||Salinity rating is low in the surface and upper subsoil becoming medium to high at depth.||The soil is non sodic in the surface and strongly sodic in the subsoil.||The clay content is high throughout the profile.|
