Jan 1, 2014 · Definition. Ortstein (German: ort -place, stein -stone) is defined by Soil Survey Staff (1992) 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. Origin: Ortstein is usually a hard, partly or entirely cemented illuvial horizon B of podzol or ...

May 1, 2011 · Orstein occurs in soils with soil temperature regimes (STR) ranging from cryic or frigid to hyperthermic as well as isomesic. However, soils with ortstein most commonly had a frigid STR. Soils with ortstein occurred in four soil mineral classes, including mixed, siliceous, isotic, and amorphic but were most common (56%) in the mixed class ( Table 2 ).

Map unit (soil).—A collection of areas with soil components or miscellaneous areas that are both defined and named the same. Each map unit differs in some respect from all others in a survey area and is uniquely identified by a symbol on a soil map. Each individual area (polygon) on the map is a “delineation.”.

Jan 1, 2014 · Abstract. Ortstein horizons are relatively common in the USA, but placic horizons are less common. Soils bearing ortstein and placic horizons are used for cranberry and blueberry culture, truck crops, and forestry operations but have many limitations for other kinds of land use. The factors influencing the distribution and formation of these ...

Jan 15, 2018 · In soil taxonomy, ortstein is defined as a layer ≥ 25 mm thick and ≥ 50% cemented (Soil Survey Staff, 2014, IUSS Working Group WRB, 2015). Formation of ortstein by cementing of soil grains is a gradual process and lasts at least a few thousand years ( Bronick et al., 2004 ).
