IT15
| Site: IT15 | Land Unit: Glenelg River Schists |
| Aust. Soil Class.: Ferric, ?, Yellow CHROMOSOL (confidence level 3) | |
| General Land Unit Description: This land unit comprises the dissected Cambrian Schist landscape of the Glenelg River and its tributaries. The major landform is rolling low hills. The major soil type is a strong texture contrast soil with many ferruginous nodules above the clay subsoil (Ferric Chromosol). The steep slopes which dominate this land unit is the major restriction for land use. |
Site Description:

| A2 | 30-50 cm | Brown (10YR5/3) sandy clay loam, weak polyhedral structure (5-20 mm), rough fabric, very weak consistence when moderately moist, a few angular quartz fragments (2-6 mm), many ferruginous nodules (6-20 mm), pH 6.0. Abrupt transition to: |
| Subsoil | ||
| B2 | 50-85 cm | Brownish yellow (10YR6/6) medium heavy clay, distinct red mottles are common, strong angular blocky structure (5-10 mm), smooth fabric, a few angular quartz fragments (2-20 mm), pH6.0. Diffuse transition to: |
| C | 85+ cm | Mica schists. |
Key profile features:
- Strong texture contrast between topsoil and subsoil
- Acidic topsoil
- Ferric horizons
