pH | Salinity Rating | |||
Surface (A1 horizon) | Strongly Acid | Very Low | Non-Sodic | None |
Subsoil (B21 horizon) | Slightly Alkaline | Very Low | Strongly Sodic | Yes 1 |
Deeper subsoil (at 85-110 cm) | Slightly Alkaline | Very Low | Strongly Sodic | Yes 1 |
The pH in the surface is strongly acid. The subsoil is slightly alkaline. | The salinity rating is very low throughout the profile. | The surface is non-sodic. The subsoil is strongly sodic. | The clay content increases markedly at the surface / subsoil boundary. |
