RANGE OF INDIVIDUAL HORIZONS:
A or Ap horizon (if it occurs):
Color--hue of 7.5YR to 2.5Y, value of 3 to 8, and chroma of 2 to 6
Texture (fine-earth fraction)-- loamy sand, loamy fine sand or sand
Bw horizon (if it occurs):
Colorhue of 7.5YR to 2.5Y, value of 5 to 7, and chroma of 6 or 8
Texture (fine-earth fraction)-- loamy sand, loamy fine sand or sand
BC horizon (if it occurs):
Colorpaler than hue of 7.5YR to 2.5Y, value of 5 to 7, and chroma of 6 or 8
Texture (fine-earth fraction)-- loamy sand, loamy fine sand or sand
C horizon:
Color--hue of 7.5YR to 2.5Y, value of 4 to 7, and chroma of 2 to 8. Colors become paler with increasing depth in many pedons. The chroma 2 colors are of uncoated sand grains and are not a redoxymorhphic feature
Texture (fine-earth fraction)-- loamy sand, loamy fine sand, or sand. Coarse sand, loamy coarse sand, and gravelly layers are in the substrata of some pedons
COMPETING SERIES:
Assateague soilsexcessively drained, silt plus clay in the control section is less than 5 percent
Buncombe soils-- have C horizons that typically have loamy textures below a depth of 40 inches and are on flood plains
Crevasse soils-- excessively drained, do not have a Bw horizon, and typically are less acid
Malden soils-- excessively drained, have more fine and very fine sand, and typically have more weatherable minerals
Peveto soils-- have neutral to moderately alkaline reaction
Rolesville soils-moderately deep to hard bedrock

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Raleigh, North Carolina
SERIES ESTABLISHED: Edgecombe County, North Carolina; 1976.
REMARKS: Tarboro soils were formerly included in the Buncombe and Molena series. However, Buncombe soils may have loamy strata below a depth of 40 inches, and Molena soils have an argillic horizon.
Diagnostic horizons and soil characteristics recognized in this pedon are:
Ochric epipedon--the zone from 0 to 8 inches (Ap horizon)
Series control section--the zone from 0 to 80 inches
