Management Considerations:
- Gradational soil with sandy component, fine sand decreases with depth and coarse sand increases with depth.
- Neutral to alkaline soil with relatively low nutrient availability, but high capacity in proportion to clay percentage.
- Weak structure of surface soil, susceptible to sheet erosion.
- Pale colour of subsoil, indicating restrictive internal drainage.
- Depositional profile, possible perched watertable with polygenetic soil.
- Landform element, drainage depression; very slow site drainage.
