TYPE LOCATION: Pitt County, North Carolina; 1/2 mile south of Winterville, North Carolina, on Highway 11, 100 feet west from road.
RANGE IN CHARACTERISTICS: Solum thickness is greater than 60 inches. The soil is strongly acid, very strongly acid, or extremely acid except where the surface has been limed.
Some pedons have an Oa horizon that has hue of 10YR, value of 2 or 3, and chroma of 1; or it is neutral and has value of 2. It is less than 8 inches thick.
The A or Ap horizon has hue of 10YR or 2.5Y or is neutral, value of 2 or 3, and chroma of 0 to 2. It is loamy fine sand, loamy sand, fine sandy loam, sandy loam, loam, or mucky analogues of these textures.
Some pedons have an Eg horizon that has hue of 10YR or 2.5Y or is neutral, value of 4 to 6, and chroma of 0 to 2. It is loamy sand, loamy fine sand, sandy loam, fine sandy loam, or loam.
Some pedons have a BEg horizon that has hue of 10YR or 2.5Y, value of 4 or 6, and chroma of 1 or 2. It is loam, sandy loam, fine sandy loam, or sandy clay loam.
The Bt horizon, where present, has hue of 10YR or 2.5Y, value of 3, and chroma of 1 or 2. It has the same textures as the Btg horizon.
The Btg horizon has hue of 10YR to 5Y, value of 4 to 7, and chroma of 1 or 2 with few to common mottles of higher chroma. The Btg horizon is sandy clay loam, sandy loam, sandy clay, or clay loam, fine sandy loam, or sandy loam.
Some pedons have a BCg horizon that has hue of 10YR or 2.5Y, value of 4 to 7, and chroma of 1 or 2. It is sandy clay loam, clay loam, sandy clay, sandy loam, or fine sandy loam.
The Cg horizon, where present, has hue of 10YR or 2.5Y, value of 5 to 7, and chroma of 1 or 2 with higher chroma mottles. It is sandy clay loam, clay loam, sandy loam, fine sandy loam, loamy fine sand, fine sand, loamy sand, or sand.
COMPETING SERIES: There are no other series in the same family. Bayboro, Byars, Cape Fear, Ellabelle, Hyde, Johnston, Lumbee, Paxville, Pocomoke, Portsmouth, Rains, Surrency, Torhunta, and Weeksville series are in closely related families. Bayboro, Byars, and Cape Fear soils have Btg horizons containing more than 35 percent clay. Ellabelle and Surrency soils have arenic umbric epipedons. Hyde soils have mixed mineralogy. Johnston, Torhunta, and Weeksville soils lack Btg horizons. Lumbee and Rains soils have ochric epipedons and, in addition, Lumbee soils have thinner sola. Pocomoke soils have sandy BCg horizons at depths of 40 to 60 inches. Portsmouth soils have mixed mineralogy and a decrease in clay of 20 percent or more within 60 inches of the surface.
GEOGRAPHIC SETTING: Pantego soils are in nearly level and slightly depressional areas of the Southern Coastal Plain and Alantic Coast Flatwoods. Slope gradients are less than 2 percent. The soil formed in medium-textured Coastal Plain deposits. Mean annual temperature is 62 degrees F. near the type location, and mean annual rainfall is about 48 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: In addition to the competing Byars, Rains, and Torhunta series, these include Coxville, Dothan, Dunbar, Duplin, Goldsboro, Lynchburg, Marlboro, Norfolk, and Rutlege series. Except for Rutlege, these soils lack umbric epipedons and are better drained than Pantego soils. Rutlege soils are sandy throughout.
DRAINAGE AND PERMEABILITY: Very poorly drained; ponded to very slow runoff; moderate permeability. The water table is at or near the surface during wet seasons.
USE AND VEGETATION: Most of the areas are in forests and the native vegetation consists of water tupelo, water, oaks, willow oak, sweetgum, blackgum, red maple, bald cypress, and pond, loblolly and slash pines. The understory includes inkberry, gallberry, sweetbay, greenbrier, southern bayberry, swamp cyrilla, switch cane and ferns. Cleared areas are used primarily for corn, soybeans, small grain, truck crops, hay, and pasture.
DISTRIBUTION AND EXTENT: Coastal Plain of Alabama, Florida, Georgia, Louisiana, Mississippi, North Carolina, South Carolina, and Virginia. The series is of moderate extent.
