Alluvial Soils
Imperfectly draining, fine-textured alluvial soil with weak horizon differentiation.
Characteristics of Alluvial Soils
- Profile morphology varies according to the age of the alluvial deposit and activity of soil forming processes
- Soil texture often varies both vertically and laterally
- Wide soil textural range from gravel to silty clay
- Variable drainage from free to very poor
- Dark, organic stained surface horizons of variable thickness
- Subsoil colour a direct result of drainage regime
- Confined to principal river valleys and stream channels
