Imperfectly draining, fine-textured
alluvial
soil with weak horizon differentiation.
|
- 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
