Soil Profile Characteristics:
| pH | Salinity Rating | ||
Surface (A1 horizon) | Moderately Acid | Low | Non-Sodic | None |
Subsoil (B21 horizon) | Slightly Acid | Very Low | Sodic | None |
Deeper Subsoil (at 90-130 cm) | Slightly Acid | Very Low | Sodic | Slight1 |
| The surface horizon is moderately acid. The subsoil is slightly acid. | | The salinity rating is low throughout the profile. | | The surface is non-sodic. The subsoil is sodic. | The clay content is low in the surface and high in the subsoil. | | |
