  1. Jan 15, 2018 · The aim of this study was to quantify the PSD and tensile strength of ortstein and overlying horizons in two podzolic soils under forest. The PSD in the range of pore size from 0.0016 to 178 μm in radius was determined in undisturbed aggregates (6–8 mm in diameter) using a mercury porosimeter.

Podzolic soils occupy 14.3% of the Canadian landmass, and occur in two widely separated areas, eastern Canada (northern Ontario, Quebec, Maritimes) and British Columbia, usually under coniferous forest and on non-calcareous parent materials ...

  3. e. The Podzolic order included Brown Podzolic or Acid Brown Wooded soils containing Podzolic B horizons that had previously been part of the Brunisol order (NSSC 1958). f. A Grey Forested great group (with Bt and no Ah) was added to Podzolic order, and represented an intergrade between Regosols and Podzolic soils (NSSC 1963, 1965). g.

  4. Jan 15, 2018 · This study elucidated the relations between the repellency index (RI) and contents of soil organic carbon (SOC), organic-complexed aluminium (Al p) and iron (Fe p), pH, specific surface area (SSA) and bulk density in the ortstein horizon and the overlying and underlying horizons in two podzolic soils under grassland and forest. The soil under grassland was originally used as a cropland.

  5. Dec 18, 2019 · The study of ortstein using a scanning electron microscope revealed that the formation of black rings within the tubular ortstein is due to an increase in the percentage of Manganese in 1.6–3.4 ...

  6. May 1, 2011 · The present summary identified elevation as a key factor distinguishing between soils with ortstein and geographically related soils without ortstein; in the USA soils with some form of ortstein often occur below 200 m elevation . About a third of the soils occurred in the Great Lakes region on sites with a seasonally high water table, primarily in the spring following melting of a thick snowpack.
