Ortstein horizon: This strongly cemented Bhc, Bhfc or Bfc horizon is at least 3 cm thick and occurs in more than one-third of the exposed face of the pedon. Ortstein horizons are generally reddish brown to very dark reddish brown.

An ortstein horizon is a Bh, Bhf, or Bf horizon that is strongly cemented and occurs in at least one-third of the lateral extent of the pedon. The ortstein horizon is designated as Bhc, Bhfc, or Bfc depending upon its organic C and extractable Fe content.
Ortstein horizons are generally reddish brown to very dark reddish brown in color. Usually Ortstein Humic Podzols have L, F, and H or O horizons and an Ae horizon. They may have mottling that indicates gleying at any depth within the control section and placic or duric horizons or a fragipan.
Although other ions like aluminum are also transferred within the profile during podzolization, the organic compounds and iron dominate the horizon colours (iron giving a reddish-brown colour and organic compounds a black colour). (Humo-Ferric Podzol)
horizon has one or more of the following: enrichment in organic matter, iron and aluminum, or clay; by the development of soil structure; or by a change of color by chemical weathering processes such as hydrolysis, reduction, or oxidation. Clay accumulation is
Jun 9, 2022 · The surface horizons are epipedons and the horizons located deep in thesoil profile are subsurface horizons. The epipedons include Anthropic, Folistic,Histic, Melanic, Mollic, Ochric, Plaggen and...
The diagnostic horizon of the Chernozemic order is an Ah horizon that has dark soil colour (due to OM enrichment), high levels of bases (especially calcium), and is at least 10 cm thick (Figure 8.19). The driest part of the Prairies is the south-eastern area of Saskatchewan and the south-western portion of Alberta; soil moisture increases as we ...
