Ortstein Humo-Ferric Podzol (OT.HFP)
Common horizon sequence: LFH, Ae, Bfc, Bfj, C
These soils have the general properties specified for the Podzolic order and the Humo-Ferric Podzol great group. They differ from Orthic Humo-Ferric Podzols by having an ortstein horizon at least 3 cm thick. An ortstein horizon in this subgroup is a Bhf or Bf horizon that is strongly cemented and occurs in at least one-third of the lateral extent of the pedon. Ortstein horizons are generally reddish brown to very dark reddish brown in color. Usually Ortstein Humo-Ferric Podzols have L, F, and H or O horizons and an Ae horizon. They may have faint mottling, and placic, duric, Ah, or Bt horizons, or a fragipan.
Note: Diagnostic horizons are underlined.
