Soil Profile Characteristics:
| pH | Salinity Rating | ||
Surface (A1 horizon) | Moderately Acid | Very Low | Non-Sodic | None1 |
Subsoil (B21 horizon) | Slightly Acid | Very Low | Non-Sodic | None |
Deeper Subsoil (at 80-110 cm) | Slightly Acid | Very Low | Non-Sodic | None |
| The surface horizon moderately acid. The subsoil is slightly acid. | | The salinity rating is very low throughout the soil profile. | | This profile is non-sodic throughout the soil profile. | | The clay content is moderate to high throughout the profile. | | Low boron count throughout the soil profile. |
