LOCATION TOTNESS SCEstablished Series
TAXONOMIC CLASS: Siliceous, thermic Typic Psammaquents
TYPICAL PEDON: Totness loamy coarse sand - forested. (Colors are for moist soil unless otherwise stated.)
A-- 0 to 7 inches; dark gray (10YR 4/1) loamy coarse sand; weak coarse granular structure; friable; common medium, and few fine roots; very strongly acid; abrupt wavy boundary. (3 to 9 inches thick)
Cg1-- 7 to 32 inches; light gray (N 7/0) coarse sand; single grained; loose; few fine roots; common coarse white flakes of feldspar; very strongly acid; gradual wavy boundary.
Cg2-- 32 to 48 inches; gray (10YR 6/1) coarse sand; single grained; loose; common coarse white flakes of feldspar; few flakes of mica; very strongly acid; clear smooth boundary. (Combined thickness of the Cg horizons is 28 to 52 inches)
Ab1-- 48 to 55 inches; black (N 2/0) mucky loam; massive; friable; common fine roots; very strongly acid; gradual wavy boundary.
Ab2-- 55 to 70 inches; dark gray (N 4/0) loam; massive; friable; very strongly acid; gradual smooth boundary
Ab3-- 70 to 74 inches; black (N 2/0) coarse sandy loam; massive; friable; very strongly acid; clear smooth boundary. (Combined thickness of the Ab horizons is 8 to 32 inches)
C-- 74 to 80 inches; very dark grayish brown (10YR 3/2) sand; single grained; loose; 1 percent white coarse fragments; strongly acid.
TYPE LOCATION: Calhoun County, South Carolina, about 10.7 miles northwest of St. Matthews; 3.3 miles west on S.C. 6 from U.S. 601; 5.8 miles north on U.S. 176 from S.C. 6; 1.6 miles west on S-9-226; site is 100 feet north of road, on the flood plain of Little Beaver Creek.
RANGE IN CHARACTERISTICS: The soil is strongly acid or very strongly acid throughout. A few flakes of mica are in some pedons.
Textures finer than loamy fine sand commonly are below the 10 to 40 inch particle-size control section; but, if they are within the control section, their weighted average does not influence the sandy particle size class. These horizons are buried surface layers, and are also noted by the irregular decrease of organic matter in the profile.
The A horizon has hue of 10YR, value of 3 or 4, and chroma of 1 or 2. Texture is sand, loamy sand, or sandy loam, or their coarse analogs.
The Cg horizon has hue of 10YR, value of 6 or 7, and chroma of 1 or 2, or it is neutral with value of 7. Texture is sand, loamy sand, or their coarse analogs.
The Ab horizon has hue of 10YR or is neutral, value of 2 to 4, and chroma of 0 or 1. Texture is coarse sandy loam, sandy loam, fine sandy loam, loam, silt loam, or rarely silty clay loam or their mucky analogs; or it is stratified with these and sandy textures.
The C or C'g horizon, below 40 inches where present, has hue of 10YR or is neutral, value of 3 to 7, and chroma of 0 to 2. Texture is sand, loamy sand, or sandy loam, or their fine and coarse analogs, and is often stratified with other textures.
COMPETING SERIES: These are the Duckston and Osier series in the same family, and the Bibb, Elloree, Johnston, Kinston, Muckalee, and Rutlege series in similar families. Duckston soils have less than 5 percent silt plus clay in the control section. Osier soils are dominantly sandy through a depth of 80 inches, and do not have thick strata of loamy material. Bibb and Muckalee soils are coarse-loamy. In addition, Muckalee soils are non-acid. Elloree soils are Alfisols. Kinston soils are fine-loamy. Johnston and Rutlege soils have a thickened umbric epipedon.
GEOGRAPHIC SETTING: Totness soils are on flood plains of streams in the Coastal Plain and Sand Hills. Slopes are less than 1 percent. The soil formed in sandy and loamy fluvial sediments. The stream channels are usually shallow and meandering. The soils flood frequently and are subject to scouring and uneven deposition of overwash. The climate is warm and humid with average annual temperature ranging from 62 to 66 degrees F., average annual precipitation ranging from 46 to 48 inches , and frost free season ranging from 220 to 240 days.
GEOGRAPHICALLY ASSOCIATED SOILS: In addition to the competing Bibb, Johnston, and Osier soils on similar landforms, are the Ailey, Alpin, Dothan, Fuquay, Noboco, Norfolk, and Vaucluse soils which occur on higher landscapes and are better drained. In addition, all except Alpin contain an argillic horizon. Alpin soils contain lamellae.
DRAINAGE AND PERMEABILITY: Poorly drained; very slow runoff; moderate permeability. The water table is within 1 foot of the surface from 6 to 11 months each year.
USE AND VEGETATION: Dominantly native woodland of gum, loblolly pine, maple, oak, willow, and tupelo.
DISTRIBUTION AND EXTENT: Coastal Plain of South Carolina and possibly Alabama, Georgia, Florida, Louisiana, Mississippi, North Carolina. The series is of small extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Raleigh, North Carolina
SERIES ESTABLISHED: Calhoun County, South Carolina, 1993.
REMARKS: Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon: 0 - 7 inches (A horizon)
The Totness series is proposed for Psammaquents that have sufficient clay increase below the particle-size control section to alter the permeability and other dependent interpretations.
Totness soils have previously been included in the Osier series in mapping.
