Surface Soil | SFS19 Profile. | ||
Ap | 0-10 cm | Dark brown (10YR3/3); light sandy loam; weakly pedal structure tending to platy at bottom of Ap; weak consistence dry; pH 6.3; clear change to: | |
A2c | 10-30 cm | Yellowish brown (10YR5/4) conspicuously bleached (10YR6/3 dry); gravelly loam; apedal structure; weak consistence dry; very many medium to coarse (5-20 mm in size) irregular cemented ferruginous nodules (remnants of Moorabool Viaduct sand) as well as rounded quartz alluvial gravel; pH 5.1; sharp and smooth change to: | |
Subsoil | |||
B21t | 30-60/70 cm | Brown (10YR5/3) with reddish yellow (7.5YR6/8) mottles; medium clay; strong coarse prismatic, parting to strong medium to coarse blocky and strong fine to medium polyhedral and lenticular structure; strong consistence dry; slickensides evident with thick cutans; pH 6.7; clear change to: | |
B/C | 60/70-80 cm | Dark red (10R3/6) and red (10R5/8) with coarse reddish yellow (7.5YR6/8) and light grey (2.5Y7/1) mottling; weathered ferruginised Moorabool Viaduct Formation sediments with clay accumulation; rigid ferruginised masses of sandier material than B21 above but with reticulate structure defined by thick bands of illuviated clay; pH 7.6. | |
C | 80+ cm | Weathered ferruginised Moorabool Viaduct Formation sediments. |
pH | Salinity Rating | |||
Surface (A1 horizon) | Slightly Acid | Low | Non-Sodic | None |
Subsoil (B21 horizon) | Slightly Acid | Very Low | Marginally Sodic | None |
Deeper subsoil (at 60-80 cm) | Slightly Alkaline | Very Low | Sodic | None |
| The salinity rating is low in the surface becoming very low in the subsoil. | The surface is non sodic. The upper subsoil is marginally sodic becoming sodic with depth. | The clay content in the surface is low and sharply increases at the surface / subsoil interface. |
