May 1, 2011 · Spodic horizons with ≥50% ortstein commonly were moderately cemented; spodic horizons with <50% ortstein were weakly cemented. Whereas 70% of the spodic horizon in soils classified with ≥50% ortstein was cemented, only 16% of the spodic horizon of soils with <50% ortstein was cemented.

the thickness of the spodic horizon were significantly greater in soils with 50 % ortstein. However, there were no significant differences between the upper or lower boundaries or the thickness of ortstein for soils with 50 % and <50 % ortstein. The ortstein horizon averaged 41 cm and 32 cm in thickness for soils with 50 %

> "Ortstein is differentiated from a placic horizon within spodic materials solely on the basis of thickness. Placic horizons within spodic materials are less than 25 mm thick, and ortstein is 25 mm or more thick."
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).

Jan 1, 2014 · The lower boundary of the spodic horizon and the thickness of the spodic horizon were significantly greater in soils with ≥50 % ortstein. However, there were no significant differences between the upper or lower boundaries or the thickness of ortstein for soils with ≥50 % and <50 % ortstein.
