TYPE LOCATION: Charleston County, South Carolina, 1-1/2 miles southeast of Hollywood on north side of field road, 650 feet south of Seaboard Airline Railroad, and 950 feet west of County Road 79.
RANGE IN CHARACTERISTICS: Solum thickness is more than 60 inches. Reaction ranges from very strongly acid through medium acid, except for surface layers that has been limed. Base saturation is more than 35 percent, generally less than 55 percent.
The A or Ap horizon has hue of 10YR, value of 3 or 4, and chroma of 1 or 2. Texture is loamy sand, loamy fine sand; sandy loam, or fine sandy loam.
The E or E' horizon has hue of 10YR or 2.5Y, value of 4 to 6, and chroma of 2 or 3. Texture is loamy sand, loamy fine sand; sandy loam, or fine sandy loam.
The Bt or horizon has hue of 10YR or 2.5Y, value of 4 or 5, and chroma of 2 to 6. Few to common mottles mostly in shades of brown are in most pedons. Some pedons have a few fine gray mottles. It is sandy loam or fine sandy loam.
The B't horizon is mottled in shades of brown, yellow, and gray with hue of 10YR to 2.5Y, value of 5 or 6, and chroma of 2 to 8. It is fine sandy loam or sandy clay loam.
The BC horizon is mottled light gray to dark gray sand, fine sand, or loamy sand.
COMPETING SERIES: There are no other known series in the family. The Coteau, Farrenburg, Frizell, Longview, and Vidrine series are similar series in related families. Coteau, Frizell, Longview, and Vidrine soils have by weight, less than 15 percent fine sand or coarser material in the control section. Farrenburg soils have 18 to 35 percent clay in the control section.
GEOGRAPHIC SETTING: Edisto soils are on the Pamlico Terrace of the lower coastal plain. They formed in thick sandy marine sediments. Near the type location mean annual temperature is 66 degrees F., mean annual precipitation is 48 inches, and the freeze-free season is 294 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Meggett, Seabrook, Stono, and Wando series, none of which have bisequal. In addition, Wando and Seabrook soils lack argillic horizons; Stono soils have mollic epipedons; and Meggett soils have more than 35 percent clay in the argillic horizons.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained; slow surface runoff; moderate permeability. The water table is 1 to 3 feet during the spring and winter months.
USE AND VEGETATION: Most of these soils are in crops or pasture; the remainder is in loblolly pines. Common crops are cabbage, potatoes, snap beans, cucumbers, tomatoes, soybeans, corn, and small grain.
DISTRIBUTION AND EXTENT: Lower Coastal Plain of South Carolina, and possibly Georgia, Florida, and North Carolina. The series is of moderate extent; more than 14,000 acres is in Charleston County, South Carolina.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Raleigh, North Carolina
SERIES ESTABLISHED: Charleston County, South Carolina, 1955.
REMARKS: This series was formerly classified as a Low-Humic Gley soil intergrading to Red-Yellow Podzolic soil.
