Knowlton soil series
A profile of a taxadjunct of the Knowlton series (fine-loamy, mixed, active, mesic Typic Endoaquults) showing the mottled color pattern (redoximorphic features) which develop under saturated conditions (Soil Survey of New River Gorge National River, West Virginia by Wendy Noll and James Bell, Natural Resources Conservation Service).
The Knowlton series consists of very deep, poorly drained soils that formed in alluvium weathered from interbedded Mississippian aged shale, sandstone, siltstone, limestone, and dolomite. Slopes range from 0 to 4 percent, but are dominantly 2 percent or less.
TAXONOMIC CLASS: Fine-silty, mixed, semiactive, mesic Typic Endoaquults
Solum thickness ranges from 40 to 60 inches or more. Depth to bedrock is greater than 60 inches. Coarse fragments, mostly rounded quartzite or sandstone gravels, range from 0 to 15 percent throughout the profile. Reaction is strongly acid to neutral in the surface layer and very strongly acid to moderately acid in the subsoil.
USE AND VEGETATION: Chiefly used as pasture, but some areas under artificial drainage are cropped to corn, soybeans, and legume-grass hay. A few isolated areas remain in woodland.
DISTRIBUTION AND EXTENT: Kentucky, West Virginia, and possibly Tennessee or Ohio. Series is moderate in extent.
The Knowlton series replaces areas previously included with the Morehead or Melvin series. The series may also be useful in replacing 1,210 acres of Peoga soils with a low base that were correlated in Montgomery County, Kentucky. The 2005 update revises the pedon description with terminology from version 2.0 of the "Field Book for Describing and Sampling Soils" after review of the original field notes. A map compilation error has placed the OSD location for this series in a delineation of Ne-Newark silt loam, frequently flooded map unit and is slated for correction during routine maintenance (Soil Survey of Powell and Wolfe Counties, Kentucky, 1993).
