TYPE LOCATION: Moore County, North Carolina; about 8.0 miles north of Carthage on Secondary Road 1640; 0.1 mile south of intersection of Secondary Road 1639 and Secondary Road 1640; 60 feet east of Secondary Road 1640 on logging road; 50 feet south of logging road in loblolly pine stand.
RANGE IN CHARACTERISTICS: Solum thickness ranges from 20 to 40 inches. Depth to paralithic contact with soft, weathered bedrock ranges from 20 to 40 inches. Reaction is very strongly acid or strongly acid unless surface layers have been limed. The content of coarse fragments 1/4 to 10 inches in size comprises from 0 to 5 percent of the A and Bt horizons. Some pedons have up to 5 percent iron and manganese concretions.
The A or Ap horizon has a hue of 10YR, value of 4 to 6, and chroma of 2 to 6. Texture is silt loam, fine sandy loam, very fine sandy loam, or loam.
The E horizon has hue of 7.5YR or 10YR, value of 6 or 7, chroma of 3 to 8. Texture is silt loam, fine sandy loam, very fine sandy loam, or loam.
The BE horizon, where present, has hue of 7.5YR or 10YR, value of 4 to 6, and chroma of 3 to 8. Texture is loam, silt loam, fine sandy loam, or silty clay loam.
The Bt horizon has hue of 5YR to 10YR, value of 4 to 7, and chroma of 4 to 8. Iron depletions in shades of gray are in some part of the Bt horizon of all pedons, and iron depletions in shades of brown or yellow are in the Bt horizon of most pedons. Most pedons also have masses of iron accumulation in shades of brown or red in some part of the Bt horizon. Texture is silty clay loam or clay loam.
The BC or CB horizon, where present, has hue of 5YR to 10YR, value of 4 to 7, and chroma of 3 to 8. Iron depletions in shades of gray, brown, or yellow are few to common, as well as masses of iron accumulation in shades of red or brown. Texture is silty clay loam, clay loam, or silt loam.
The C horizon, where present, has hue of 2.5YR to 7.5YR, value of 4 to 6, and chroma of 3 to 8 with iron depletions in shades of gray, yellow, or brown, and iron accumulations in shades of red or brown. Texture is silt loam, very fine sandy loam, fine sandy loam, or loam.
The Cr horizon has hue of 10R to 7.5YR, value of 3 to 6, and chroma of 2 to 8. It is weathered Triassic siltstone, mudstone, or fine-grained sandstone that is partially consolidated but can be dug with difficulty with a spade.
COMPETING SERIES: These are the Margo and Yeopim series in the same family, and the Brickhaven, Carbonton, and Hallison series in a closely related family. Margo and Yeopim soils do not have a Cr horizon. Brickhaven and Carbonton soils are fine, mixed, semiactive, thermic Oxyaquic Hapludalfs. In addition, Brickhaven soils have a Cr horizon at a depth of 40 to 60 inches. Hallison soils are Typic Hapludults, and in addition have a Cr horizon at a depth of 40 to 60 inches.
GEOGRAPHIC SETTING: Mooshaunee soils are on gently sloping to moderately steep ridges and side slopes in Triassic Basins of the Southern Piedmont. Slopes are generally 2 to 15 percent but range up to 25 percent. These soils formed in residuum weathered from Triassic siltstones, mudstones, and sandstones. Mean annual precipitation is 47.6 inches and mean annual air temperature is 61.5 degrees F. near the type location.
GEOGRAPHICALLY ASSOCIATED SOILS: In addition to the competing Brickhaven, Carbonton, and Hallison soils, these are the Mayodan, Pinkston, Creedmoor, White Store, Polkton, and Granville soils. Mayodan and Creedmoor soils are clayey and lack a Cr horizon. Pinkston soils contain less clay and are underlain with hard bedrock at depths of 20 to 40 inches. White Store soils are clayey and have a Cr horizon at depths greater than 48 inches. Polkton soils are clayey. Granville soils lack a Cr horizon, have lower silt content, and siliceous mineralogy.
DRAINAGE AND PERMEABILITY: Moderately well drained; medium to rapid runoff; moderate and moderately slow permeability.
USE AND VEGETATION: This soil is mostly in woodland. Some small areas are in cropland and pasture. Common trees include loblolly pine, shortleaf pine, southern red oak, white oak, sweetgum, red maple, hickory, and yellow poplar. Understory plants include flowering dogwood, American holly, blueberry, and ginger.
DISTRIBUTION AND EXTENT: The Triassic Basins in the Southern Piedmont of North Carolina and possibly South Carolina. This series is of minor extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Raleigh, North Carolina
SERIES ESTABLISHED: Moore County, North Carolina; 1987.
REMARKS: Diagnostic horizons and soil characteristics recognized in the typical pedon are:
Ochric epipedon - the zone from the surface to a depth of 10 inches (A and E horizons)
Argillic horizon - the zone between depths of 10 and 37 inches (Bt1, Bt2, Bt3, and Bt4 horizons).
Paralithic contact - the contact with weathered bedrock at a depth of 37 horizons (upper boundary of the Cr horizon).
