Distinguishing features
Topsoil
- Pale grey, white or pale yellow in colour.
- Mainly acid pH.
Subsoil
- Subsoil dominated by sand to depths of at least 80cm.
- Subsoils often highly leached, poor nutrient status and retention.
- Less than 20% Ironstone gravel maybe present below 15cm depth in a band at least 20cm thick (443).
- Deep subsoils (>80cm) may contain clay, ferricrete or coffee rock (443, 444).
