- | pH | Salinity Rating | ||
Surface (A1 horizon) | Slightly Acid | Very Low | Non-Sodic | None |
Subsoil (B21 horizon) | Slightly Alkaline | Very Low | Sodic | Complete |
Deeper Subsoil (at 1 m) | Very Strongly Alkaline | Low | Sodic | Complete |
The surface soil is slightly acid. The subsoil is slightly alkaline becoming very strongly alkaline at depth. | The salinity rating is very low in the surface and upper subsoil becoming low with depth. | The surface is non-sodic. The subsoil is sodic. | The clay content increases markedly at the surface / subsurface boundary. |
