2C--33 to 60 inches; reddish yellow (7.5YR 6/6) sand; few coarse distinct strong brown (7.5YR 5/6) mottles that are sandy loam; massive; loose; few small rounded pebbles of quartz; sand becomes lighter in color and coarser with depth; small pebbles increase in abundance with depth; strongly acid.
TYPE LOCATION: Scotland County, North Carolina; 3 miles north of Maxton on North Carolina Highway 71; 50 feet northwest of Sycamore Hill Cemetery.
RANGE IN CHARACTERISTICS: Solum thickness ranges from 20 to 40 inches. Reaction of the solum is very strongly acid or strongly acid unless the surface has been limed. Flakes of mica range from none to few. Gravels or pebbles range from 0 to 10 percent.
The Ap or A1 horizon has hue of 7.5YR through 2.5Y, value of 4 to 6, and chroma of 1 to 4. Texture is loamy sand, sandy loam, or fine sandy loam.
The E horizon has hue of 10YR or 2.5Y, value of 5 to 7, and chroma of 3 or 4. Texture is loamy sand, sandy loam, or fine sandy loam.
The BE horizon has hue of 5YR to 10YR, value of 4 to 7, and chroma of 2 to 8. Texture is sandy loam, fine sandy loam, or sandy clay loam.
The Bt horizon has hue of 2.5YR or 5YR, value of 4 to 6, and chroma of 3 to 8. Texture is sandy clay loam or sandy loam. Content of silt is less than 20 percent.
The BC horizon has hue of 2.5YR or 5YR, value of 4 to 6, and chroma of 3 to 8. Texture is sandy loam or sandy clay loam. It contains considerably less clay than the Bt horizon.
The 2C horizon has hue of 5YR to 2.5Y, value of 5 to 8, and chroma of 3 to 8. It is stratified loamy sand, sand, coarse sand, or gravelly sand.
COMPETING SERIES: These include the Altavista, Cahaba, Kalmia, Masada, Norfolk, Orangeburg, Rumford, Ruston, and Wickham series. All of these soils except Kalmia soils have sola more than 40 inches thick. Altavista soils have redoximorphic depletions of chroma 2 or less within 24 inches of the top of the argillic horizon. Cahaba soils have more than 20 percent silt in the control section. Kalmia and Masada soils have an argillic horizon in hue of 10YR or 7.5YR. Norfolk, Orangeburg, and Ruston soils have sola more than 60 inches thick. Rumford soils have less than 18 percent clay in the control section. Wickham soils have mixed mineralogy.
GEOGRAPHIC SETTING: Maxton soils are most extensive on nearly level slopes on low terraces of larger streams and marine terraces at low elevations, but are of moderate extent on sideslopes. Dominant slopes are 0 to 3 percent but range to 6 percent. These soils formed in coarse-textured marine or stream deposits. Mean annual temperature is 62.5 degrees F, near the type location, and mean annual rainfall is about 46 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: In addition to the competing Kalmia series, these include the Johns and Lumbee series. Johns and Lumbee soils are not as well drained and have redoximorphic depletions in the Bt horizons.
DRAINAGE AND PERMEABILITY: Well drained; medium runoff; moderate permeability.
USE AND VEGETATION: Used mainly for corn, cotton, soybeans, tobacco, and truck crops. Originally forested loblolly, shortleaf, and longleaf pine, white and southern red oaks, sweetgum, and yellow-poplar.
DISTRIBUTION AND EXTENT: North Carolina, South Carolina, Georgia, Florida, Alabama, and Virginia. The series is of moderate extent.
