   Jan 1, 2014 · Properties: Ortstein is 25 mm or more thick and 50% or more (by volume) cemented (Soil Survey Staff, 1999). As a rule, the horizon has sandy grain-size distribution. Compared to the adjacent non-cemented horizons, ortstein usually has a higher bulk density (Lambert and Hole, 1971; Wang et al., 1978).

   Ortstein - This strongly cemented horizon (Bhc, Bhfc, or Bfc) 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.

   These soils have the general properties specified for the Podzolic order and the Ferro-Humic Podzol great group. They differ from Orthic Ferro-Humic Podzols by having an ortstein horizon at least 3 cm thick. 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 averaged 41 cm and 32 cm in thickness for soils with 50 % and <50 % ortstein, respectively. The degree and proportion of cementation were significantly greater in soils with 50 % ortstein than in those with <50 % ortstein (Table 18.1). Spodic horizons with 50 % ortstein commonly were moderately

   How thick is Ortstein?

   • According to Soil Taxonomy (ST), ortstein consists of spodic materials and occurs in a layer that is ≥25 mm thick and ≥50 % cemented (Soil Survey Staff 2010) (Fig. 18.1). In ST, ortstein is both a diagnostic subsurface horizon and the only rupture-resistance class recognized in the system.

   How thick is a soil with 50 % Ortstein?

   • The ortstein horizon averaged 41 cm and 32 cm in thickness for soils with ≥50 % and <50 % ortstein, respectively. The degree and proportion of cementation were significantly greater in soils with ≥50 % ortstein than in those with <50 % ortstein (Table 18.1).

   Which soils contain Ortstein?

   • Eight of the soils are developed under excessively to well-drained conditions in relatively uniform sandy outwash, and yet they contain ortstein. These include the Copemish, Crowell, Garlic, Pullup, Wallace, Kaleva, Kalkaska, and Netarts series. All of these series occur in northern MI except for the Netarts which exists along the OR coast.

   Is Ortstein common in a well drained soil?

   • In this analysis, ortstein was common not only in poorly drained soils of FL and soils with a seasonally high water table in all of the regions but also in well-drained to excessively drained soils derived from relatively uniform outwash sand in northern MI.

   What is the difference between 50 % Ortstein and 50 % Ortstein?

   • Whereas soils with ≥50 % ortstein commonly had a massive structure (64 % of soil series), soils with <50 % ortstein and those lacking ortstein often had a subangular blocky structure (74 % and 54 %, respectively) (Table 18.2).

   Which soil series have Ortstein-like Horizons?

   • There are at least three soil series classified as Andisols that have ortstein-like horizons that are <50 % cemented with Fe, Al, and Mn. These include the Getchell, Hoquiam, and Hoko series, which are classified as Haplocryands, Fulvudands, and Durudands, respectively. These series account for 71,000 ha on the Olympic Peninsula of western WA.
