LOCATION SEEWEE SC+FLEstablished Series
The Seewee series consists of very deep, somewhat poorly drained, moderately rapidly permeable soils that formed in sandy marine sediments. Slopes range from 0 to 2 percent.
TAXONOMIC CLASS: Sandy, mixed, thermic Aeric Alaquods
TYPICAL PEDON: Seewee loamy fine sand--forested. (Colors are for moist soil.)
A1--0 to 6 inches; black (10YR 2/1) loamy fine sand; weak, fine granular structure; very friable; many fine and medium roots; extremely acid; clear smooth boundary. (5 to 7 inches thick)
A2--6 to 11 inches; dark grayish brown (10YR 4/2) loamy fine sand; weak, fine granular structure; very friable; many fine and few medium roots; strongly acid; clear smooth boundary. (3 to 9 inches thick)
E--11 to 21 inches; brown (10YR 5/3) loamy fine sand; common medium faint yellowish brown (10YR 5/6) and few medium faint pale brown (10YR 6/3) mottles; weak, fine, granular structure; very friable; few fine roots; strongly acid; clear smooth boundary. (6 to 18 inches thick)
Bh--21 to 30 inches; dark brown (10YR 3/3) fine sand; few fine faint dark grayish brown (10YR 4/2) and grayish brown (10YR 5/2) mottles; massive; firm in place; slightly brittle, loose when crushed; few fine roots and pores; old root holes and pores stained red (2.5YR 5/6); sand grains coated with organic matter; strongly acid; gradual wavy boundary. (8 to 24 inches thick)
Cg1--30 to 48 inches; grayish brown (10YR 5/2) fine sand; common medium faint dark brown (10YR 3/3) and yellowish brown (10YR 5/6) mottles; single grained; loose; strongly acid; gradual wavy boundary. (14 to 22 inches thick)
Cg2--48 to 65 inches; light brownish gray (2.5Y 6/2) fine sand; common medium distinct yellowish brown (10YR 5/6) mottles; single grained; loose; strongly acid.
TYPE LOCATION: Charleston County, South Carolina; 2 miles northwest of McClellanville, 0.4 mile west of State Highway 45 along Randall Road (U. S. Forest Service No. 234).
RANGE IN CHARACTERISTICS: The soil is extremely acid to slightly acid in the A horizon and very strongly acid to moderately acid in the Bh and C horizons. Depth to the Bh horizon ranges from 18 to 30 inches.
The A or Ap horizon has hue of 10YR or 2.5Y, value of 2 to 4, and chroma of 1 or 2. The A and Ap horizons are loamy fine sand, loamy sand, or fine sand.
The E horizon has hue of 10YR or 2.5Y, value of 5 or 6, and chroma of 2 to 6. Pedons that have an E horizon with chroma of 2 have a layer in the E horizon with chroma of 3 or more. The E horizon is loamy fine sand, loamy sand, or fine sand.
The Bh horizon has hue of 5YR to 5Y, value of 2 or 3, and chroma of 1 to 4. It does not turn redder in ignition. The Bh horizon is fine sand or sand.
The C horizon has hue of 10YR or 2.5Y, value of 4 to 7, and chroma of 1 to 4, commonly with mottles in shades of brown or yellow. Some pedons are mottled in the above colors. The C horizon is fine sand or sand.
COMPETING SERIES: There are no other known series in this family. Similar soils in other families are the Baratari, Echaw, Leon, Lynn Haven, Olustee, Mascotte, Ridgeland, Rosedhu, Seagate, and Witherbee series. Baratari soils have an E horizon with chroma 2 or less. Echaw, Leon, Lynn Haven, Mascotte, Olustee, Seagate, and Witherbee soils have siliceous mineralogy. Mascotte, Olustee, and Seagate soils have an argillic horizon beneath the Bh horizon. Ridgeland soils do not have an E horizon. Rosedhu soils have an umbric epipedon.
GEOGRAPHIC SETTING: Seewee soils are on level or nearly level broad ridges and flats at elevations of 5 to 25 feet above sea level, along the Atlantic Coast. The soil formed in thick beds of sandy marine sediments. Average annual rainfall is about 49 inches. Freeze-free growing season averages 280 days.
GEOGRAPHICALLY ASSOCIATED SOILS: In addition to the similar Baratari, Ridgeland, and Rosedhu series, these are the Fripp, Kiawah, Polawana, Seabrook, and Wando series. Fripp, Kiawah, Polawana, Seabrook, and Wando soils do not have a Bh horizon.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained; slow runoff; permeability is rapid in the A horizons and moderately rapid in the Bh horizons. The water table is within 1.0 to 2 feet of the soil surface for as much as 6 months in most years.
USE AND VEGETATION: Most areas are forested. Principal trees are loblolly pine, longleaf pine, sweetgum, and water oak. Cultivated areas are used for tomatoes, snapbeans, cucumbers, soybeans, and pasture.
DISTRIBUTION AND EXTENT: Lower Coastal Plain of South Carolina, possibly Georgia, Florida, and North Carolina. The series is of moderate extent.
