TYPE LOCATION: Dorchester County, South Carolina, three miles southwest of Ridgeville, one mile southeast of the junction of S.C. Highway 19 and S.C. Highway 136, site is 100 feet west of S.C. Highway 136 in wooded area.
RANGE IN CHARACTERISTICS: Silt content of the particle size control section is more than 30 percent. Reaction is very strongly acid to moderately acid throughout.
The A or Ap horizon has hue of 10YR or 2.5Y, value of 2 to 6 and chroma of 1 or 2. It is loamy fine sand, fine sandy loam, loam or silt loam.
The E horizon, where present, has hue of 10YR or 2.5Y, value of 5 to 7, and chroma of 2 to 4. It is loamy fine sand, fine sandy loam, loam, or silt loam.
The Btg horizon has hue of 7.5YR to 5Y, value of 5 to 7, and chroma of 1 or 2. Most pedons have iron accumulations and depletions in shades of red, brown, yellow, or gray or it is a combination of these colors. It is loam, silt loam, or clay loam.
The BCg horizon has colors similar to the Btg. It is sandy clay loam or clay loam.
COMPETING SERIES: (This section has not been updated; 2/97) These are the Lynchburg series in the same family and the Stallings, Nahunta, Dunbar, Lenoir and Yemassee series in similar families. Lynchburg and Yemassee soils have less than 30 percent silt in their control sections. Stallings soils are coarse-loamy, Nahunta soils are fine-silty, and Dunbar and Lenoir soils are clayey.
GEOGRAPHIC SETTING: Jedburg soils are on broad flats or slightly depressional areas on terraces on the Coastal Plain. Slopes range from 0 to 2 percent. The soil formed in loamy and silty marine and fluvial sediments. Near the type location, the mean annual temperature is 62 degrees F., and the mean annual precipitation is approximately 48 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: In addition to the competing series, these are the Bonneau, Daleville, Grifton, Izagora, Noboco and Persanti series. Bonneau soils are arenic. Daleville and Grifton soils have chroma of 2 or less throughout their profile. Grifton soils are Alfisols. Bonneau, Izagora, Noboco and Persanti soils are Udults.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained; slow runoff and moderately slow permeability. Areas on low terraces may be subject to rare flooding.
USE AND VEGETATION: Most areas are in pines with an understory of myrtle, blackberry, gallberry and broom sedge. Some areas have been cleared for row crops or pasture or have been cleared and replanted to pines.
DISTRIBUTION AND EXTENT: Coastal plain of Alabama, South Carolina and Virginia, and possibly North Carolina and Georgia. The series is of large extent.
