Dadswells Series
Soils included in this series have distinct texture contrasts between hard setting surface soil horizons and moderately to strongly pedal clayey subsoils. Conspicuously bleached A2 horizons are present. The uppermost subsoil layer, that is at least 15 cm thick is mottled and dominantly yellow to yellow-grey. The soil reaction trend is neutral.
In the present survey, this series consists of one soil type:
Dadswells Sandy Loam (DA sl)
Profile Morphology:
Surface Soil - A1 horizon
- About 10 cm thick.
- Brown to dark reddish brown.
- Sandy loam.
Surface Soil - A2 horizon
- About 2-5 cm thick.
- Light brown to light reddish brown (moist), conspicuously bleached near white (dry).
- Sandy loam to loamy sand.
Subsoil
- Mottled brown, reddish brown and yellowish brown and/or grey.
- Medium to heavy clay.
Analytical data for selected depths down the profile:
Depth | pH | Total Soluble Salts | Sodium Chloride | Moisture Retention @ 15-Bar | Moisture Retention @ 1/3-Bar |
. | . | % | % | % | % |
A | 5.8 | 0.020 | * | 3.5 | 7.4 |
B | 6.4 | 0.085 | 0.054 | 25.9 | 35.7 |
C | 7.2 | 0.174 | 0.113 | 20.9 | 32.9 |
* Sodium Chloride contents were not measured and are expected to be very low (based on TSS <0.05%).
Occurrence:
Dadswells Sandy Loam usually occurs in the flood plains.
