- 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.

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.

Four types of cemented layers are found in Podzolic soils: Ortstein horizons, Duric horizons, Placic horizons, and fragipans. The first three are denoted with a c suffix (for example, Bhfc, Bfc, BCc) and fragipans are assigned an x suffix (Bx, BCx).
Jan 1, 2014 · Ortstein (German: ort-place, stein-stone) is defined by Soil Survey Staff as all or part of the spodic horizon, when moist, it is at least weakly cemented into a massive horizon that is present in more than half of each pedon.

Jan 1, 2016 · A hardpan cemented with iron and organic matter, that forms in acid soils, most commonly in the B horizon of a Podzol, where it tends to form at the top of the water table. The Eh‐pH diagram (Figure O1) illustrates the process. Water in the zone of saturation contains ferrous iron in solution.

Horizons. The action and interaction of soil-forming processes as influenced by soil-forming factors gives rise to distinct soil horizons. These layers are assigned distinctive alphabetic symbols as a form of shorthand for their characteristics.
