May 1, 2011 · 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 2). Soils with ≥50% ortstein generally had a hard to extremely hard dry consistence (57%), whereas soils with <50% ortstein and those without ortstein had a consistence of ...

May 1, 2011 · Soils with ortstein cover 2.2 million ha in the USA, 87% of which occur in Michigan and Florida. Of the 650 soils in the National Soil Survey database classified as Spodosols, 47 contain ...
May 1, 2011 · 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. The data suggest that soil water transporting cementing materials (Fe, Al, Si, and dissolved organic C) moves more slowly in landscape positions where ortstein eventually forms than in those where it is absent.

May 1, 2011 · Soils with ortstein cover 2.2 million ha in the USA, 87% of which occur in Michigan and Florida. Of the 650 soils in the National Soil Survey database classified as Spodosols, 47 contain sufficient ortstein to be classified in the ortstein rupture-resistance class; another 42 soils contain materials that are 5% ortstein (89 series) were compared with geographically associated and competing ...
The solum is 16 to 28 inches thick. Depth to the ortstein ranges from 6 to 15 inches, and ranges from 1 to 3 inches thick. Gravel content ranges from 0 to 5 percent throughout the pedon. The soil is saturated to the surface for 90 to 120 days when the soil temperature is above 5 degrees C.
