Salinity Rating | |||
Surface (A1 horizon) | Strongly Acid | Medium | Non-Sodic |
Subsoil (B21 horizon) | Strongly Acid | Low | Non-Sodic |
Deeper Subsoil (at 90 cm) | Strongly Acid | Low | Slightly Sodic |
This profile is strongly acid. | The salinity rating in the surface is medium. The subsoil has a low salinity rating. | This profile is non-sodic down to the deeper subsoil where the soil is slightly sodic. | Low to moderate clay content. |
