TYPE LOCATION: Charleston County, South Carolina; on James
Island, 3 miles southwest of Charleston, 200 feet west of S.C. Highway 171, across highway from Westchester subdivision.
RANGE IN CHARACTERISTICS: Solum thickness is 35 to 60 inches.
The soil is strongly acid or medium acid in the A horizon and
medium acid or slightly acid in the B and C horizons. Few to
common concretions are throughout the soil.
The A1 or Ap horizons has hue of 10YR or neutral, value of 2 or 3, and chroma of 1 or 2. The A2 horizon has hue of 10YR, 2.5Y, or neutral, value or 4 to 6, and chroma of 0 to 2. The A horizon is loamy fine sand or loamy sand.
The B horizon has hue of 10YR or 2.5Y, value of 4 to 6, and chroma
of 2, with mottles in shades of yellow or brown. In some pedons,
the B horizon is mottled in shades of gray, yellow, or brown. It
is loamy fine sand or loamy sand. The particle size control
section has 3 percent or more clay than the A2 horizon. Some
pedons have strata less than one inch thick of finer textured material.
The C horizon is mottled in various shades of gray, yellow, or
brown. It is sand or fine sand.
COMPETING SERIES: There are on other known series in this family. The
series are similar soils in other families. Lynchburg, Plummer,
and Rains soils are fine-loamy. Patterson soils are coarse-loamy. Osier and Seabrook soils do not have a Bt horizon.
GEOGRAPHIC SETTING: Kiawah soils are on nearly level areas of the Pamlico terrace at elevations of 5 to 20 feet above sea level. Slopes are less than 2 percent. The soil formed in thick sandy marine sediments. The mean annual temperature is about 66 degrees F., and mean annual precipitation is about 49 inches. The
frost-free growing season is 280 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the similar
Seabrook series and the
Wando series. Charleston soils have an argillic horizon containing 12 to 18
percent clay. Edisto soils are bisequal. Seewee soils have a Bh horizon. Wando soils do not have a Bt horizon.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained; slow runoff; rapid permeability, but is is impeded by the high water table.
USE AND VEGETATION: Some areas are cleared, with cabbage,
tomatoes, soybeans, and Irish potatoes the principal crops. Corn
and small grains are minor crops. Most areas are in forest. Principal trees are loblolly pine, sweetgum, and water oaks.
DISTRIBUTION AND EXTENT: South Carolina, North Carolina, Georgia, and possibly Florida. The series is of moderate extent.
