May 1, 2011 · Because soils with and without ortstein often occur on the same landforms, soils containing >5% ortstein (89 series) were compared with geographically associated and competing soil series (59) that lack ortstein, using analysis of variance.

May 1, 2011 · Soils with some form of ortstein were classified primarily into four soil temperature classes, including frigid (38 soil series), mesic (20), hyperthermic (16), and isomesic (7). The dominant mineralogy class was mixed (50 soil series), followed by siliceous (21), isotic (15), and amorphic (3).

Jan 1, 2014 · In gley-podzol soils, some iron and manganese compounds may come from precipitation from groundwater (Chodorowski, 2009). A huge accumulation of the complexes leads to the formation of coherent aggregates, and even of continuous, highly cemented layers referred to as ortstein.

May 1, 2011 · Soils with ortstein occur on lesser slopes (p = 0.001) and at lower elevations (p = 0.015) than soils without ortstein. The lower depth boundary and thickness of the spodic horizon were...
Organic Some soils have podzolic B horizons underlying a thick layer of peat or folic materials. The soil is classified as Organic if the peat layer is either 60 cm or more in depth and consists of fibric materials, or 40 cm or more in depth if it consists of mesic, humic, or folic materials.
poor drainage as only 39% of the soils with ortstein have an aquic soil moisture regime. From a weight-of-evidence assessment, ortstein is cemented by Al-organic complexes and short-range-order compounds, and placic horizons are cemented by Fe as ferrihydrite or as Fe-organic complexes.

May 1, 2011 · Soils with ortstein occur on lesser slopes (p = 0.001) and at lower elevations (p = 0.015) than soils without ortstein. The lower depth boundary and thickness of the spodic horizon were significantly greater (p = 0.001) in soils with ortstein than in those without ortstein.
