Carbonton soil series

The Carbonton series consists of moderately deep, somewhat poorly drained soils with slow permeability. They formed in residuum from Triassic siltstone, mudstone, conglomerate, and shale. These soils are on uplands of the Triassic Basin in the Southern Piedmont. Slope ranges from 2 to 40 percent.

 

TAXONOMIC CLASS: Fine, mixed, semiactive, thermic Oxyaquic Hapludalfs

 

Solum thickness ranges from 20 to 40 inches. Depth to paralithic contact with weathered bedrock (Cr) ranges from 20 to 40 inches. Depth to a lithic contact with unweathered bedrock (R) is 40 to more than 60 inches. Rock fragments are less than 35 percent by volume in the A or Ap horizon, less than 15 percent by volume in the E, BE, Bt, and BCt horizons, and less than 35 percent by volume in the C horizon. Exchangeable aluminum is high (greater than 10 meq/100g). Reaction ranges from extremely acid to strongly acid except where surface layers have been limed.

 

USE AND VEGETATION: Most of this soil is in woodland with some small areas in pasture. Forested areas are loblolly pine, shortleaf pine, southern red oak, white oak, and hickory. Understory species are dominantly red maple, sweet gum, eastern red cedar, flowering dogwood, and sourwood.

 

DISTRIBUTION AND EXTENT: Triassic Basins of the thermic Southern Piedmont of North Carolina and possibly South Carolina and Virginia. The series has small extent.
