pH | Salinity Rating | |
Surface (A1 horizon) | Slightly Acid | Medium |
Subsoil (B21 horizon) | Slightly Alkaline | Low |
Deeper Subsoil (at 90-130 cm) | Very Strongly Alkaline | Medium |
The surface is slightly acid. The upper subsoil is slightly alkaline and the deeper subsoil is very strongly alkaline. | The salinity rating in the surface is medium The upper subsoil has a low salinity rating becoming medium at depth. |
