TYPICAL PEDON: Yanceyville sandy loam in an area of Rhodhiss sandy loam, 15 to 45 percent slopes, forested. (Colors are for moist soil unless otherwise stated.)

A--0 to 6 inches; dark yellowish brown (10YR 4/4) sandy loam; weak medium granular structure; very friable; very strongly acid, pH 5.0; clear smooth boundary. (2 to 9 inches thick)

E--6 to 12 inches; light yellowish brown (10YR 6/4) sandy loam; weak medium granular structure; very friable; very strongly acid, pH 5.0; gradual wavy boundary. (0 to 8 inches thick)

Bt1--12 to 26 inches; yellow (10YR 7/6) sandy loam; weak medium subangular blocky structure; very friable; 5 percent fine faint yellow (10YR 7/8) mottles; very strongly acid, pH 5.0; gradual wavy boundary.

Bt2--26 to 37 inches; very pale brown (10YR 7/4) loam; weak medium subangular blocky structure; friable; 10 percent medium faint yellow (10YR 7/8) mottles; strongly acid, pH 5.5; gradual wavy boundary. (Combined thickness of the Bt horizons is 10 to 30 inches)

BC--37 to 49 inches; very pale brown (10YR 7/4) sandy loam; weak fine subangular blocky structure; very friable; 10 percent medium distinct white (10YR 8/1) and 15 percent medium faint yellow (10YR 7/8) mottles; strongly acid, pH 5.5; gradual wavy boundary. (0 to 20 inches thick)

C--49 to 80 inches; reddish yellow (7.5YR 6/8) and white (10YR 8/1) and yellow (10YR 7/8) sandy loam; massive structure; very friable; strongly acid, pH 5.5.

TYPE LOCATION: Caswell County, North Carolina; Yanceyville sandy loam, 15 to 45 percent slope, in an area of Rhodhiss complex, 2 to 6 percent slopes; from the community of Pelham, 1.60 mile east southeast on Shady Grove (SR 1360) from the intersection of US Old Highway 29 and Shady Grove(SR 1360); 0.7 mile south on Mill Ridge Road(gravel road); 1,200 feet south southwest of curve on Mill Ridge Road, in mixed hardwoods; Park Springs, NC USGS topographic quadrangle; lat. 36 degrees 29 minutes 56.00 seconds N. and long. 79 degrees 26 minutes 56.10 seconds W.

RANGE IN CHARACTERISTICS: Solum thickness ranges from 20 to 40 inches. The solum is underlain by saprolite. Depth to bedrock, both hard and weathered, is more than 5 feet. Content of rock fragments ranges from 0 to 35 percent throughout, but individual subhorizons range up to 60 percent. Rock fragments consist of gravel, cobbles, stones and boulders. Reaction ranges from very strongly acid to moderately acid. Flakes of mica range from none to common in all horizons.

The A horizon is has hue of 7.5YR to 2.5Y, value of 3 to 6, and chroma of 2 to 4. It is fine sandy loam, sandy loam, loamy sand, or loamy coarse sand in the fine-earth fraction.

The E horizon, where present, has hue of 7.5YR to 2.5Y, value of 3 to 6, and chroma of 2 to 4. It is fine sandy loam, sandy loam, loamy sand, or loamy coarse sand in the fine-earth fraction.

The Bt horizon has hue of 2.5YR to 10YR, value of 4 to 7, and chroma of 4 to 8. Mottles range from none to common and are in shades of red, brown, and yellow. Texture is dominantly sandy loam, coarse sandy loam, or loam in the fine-earth fraction. Some pedons may have thin subhorizons of sandy clay loam.

The BC, where present, has colors and textures similar to the Bt, but may include loamy sand.

The C horizon is highly weathered saprolite from felsic igneous and metamorphic rock, primarily granite and granite gneiss.

The Cr horizon, where present, is weathered felsic igneous and metamorphic rock, primarily granite and granite gneiss.

The R horizon, where present, is hard felsic igneous and metamorphic rock, primarily granite and granite gneiss.

COMPETING SERIES: There are no known soils in this family. Similar soils in other families are the Bannertown, Devotion, Rhodhiss, and Stott Knob soils. Bannertown soils are moderately deep to hard bedrock. Devotion soils are moderately deep to soft bedrock and deep or very deep to hard bedrock. Rhodhiss soils are very deep to bedrock and have a fine-loamy particle-size control section. Stott Knob soils are moderately deep to soft bedrock and have a fine-loamy particle-size control section.

GEOGRAPHIC SETTING: Yanceyville soils are on sloping ridgetops and sideslopes of the Piedmont uplands. Slopes range from 6 to about 45 percent. The soil formed in material weathered from felsic igneous and metamorphic rock, primarily granite and granite gneiss. The mean annual temperature ranges from 59 to 65 degrees F, and the mean annual precipitation ranges from 45 to 52 inches.

GEOGRAPHICALLY ASSOCIATED SOILS: In addition to the similar Bannertown, Devotion, Rhodhiss, and Stott Knob soils, these include the Clifford, Fairview, Nathalie, Siloam, and Toast series. Clifford, Fairview, Nathalie, and Toast are in the fine family. Siloam soils are in a shallow family.

DRAINAGE AND PERMEABILITY: Well drained to excessively drained; runoff is medium to rapid; permeability is moderately rapid.

USE AND VEGETATION: Mostly forested with post oak, white oak, and red oaks but there are some hickories, dogwoods, and shortleaf and loblolly pines. Cultivated areas are used for corn, oats, tobacco, vegetables, and pasture.

DISTRIBUTION AND EXTENT: The Southern Piedmont MLRA 136(mesic part) of North Carolina and Virginia. The series is not extensive.

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Raleigh, North Carolina

SERIES ESTABLISHED: Caswell County, North Carolina; 2016

REMARKS: Yanceyville soils were previously mapped as Louisburg soils. The April 1997 relocation of the mesic/thermic line in North Carolina and Virginia necessitated the establishment of the Yanceyville series as a mesic counterpart to the Louisburg series.

Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon - the zone from the surface of the soil to a depth of 12 inches (A and E horizons)
Argillic horizon - the zone from 12 to 37 inches below the surface (Bt1 and Bt2 horizons).
