pH | Salinity Rating | |||
Surface (A1 horizon) | Moderately Acidic | Very Low | Non-Sodic | None |
Subsoil (B21 horizon) | Strongly Acidic | Very Low | Non-Sodic | None |
Deeper Subsoil (at 80 + cm) | Moderately Acidic | Low | Non-Sodic | None |
This profile is moderately acid in the surface. The upper subsoil is strongly acid becoming moderate with depth. | The salinity is low throughout the profile. | The surface and subsoil is non sodic. The deeper subsoil is strongly sodic. |
| The clay content is low throughout the profile. |
