Key Profile Features:
- Strong texture contrast between surface (A) horizon and subsoil (B21) horizon
| pH | Salinity Rating | ||
Surface (A1 horizon) | Slightly alkaline | Very low | Sodic | |
Subsoil (B21 horizon ) | Moderately alkaline | Very low | Strongly sodic | |
Deeper subsoil (90-130 cm) | Extremely alkaline | Low-Medium | sodic | |
- 1 Due to high levels of soluble salts.
