(5 to 15 inches thick)
Btx2--28 to 48 inches; gray (5Y 6/1) silty clay loam; moderate very coarse prismatic structure parting to moderate medium subangular blocky; very firm; many prominent gray (5Y 5/1) clay films on prism faces; few fine black (10YR 2/1) manganese concretions; common medium prominent yellowish brown (10YR 5/8) masses of iron accumulation; brittle in 80 percent of the mass; very strongly acid; gradual wavy boundary. (10 to 30 inches thick)
Cg--48 to 60 inches; gray (N 6/0)silty clay loam; massive, firm, slightly sticky, slightly plastic; common fine black (10YR 2/1) manganese concretions; common medium prominent strong brown (7.5YR 5/6) masses of iron accumulation; very strongly acid.
TYPE LOCATION: Rowan County, Kentucky; about 3.6 miles northwest of Farmers, 1.2 miles southeast of intersection of Interstate 64 and SR 1722, 0.9 mile west of intersection Farmers Club Road and SR 1722 in cultivated field. USGS Farmers Quad (Latitude: 38 degrees, 09 minutes, 3.2 seconds N; Longitude: 83 degrees, 36 minutes, 45 seconds W).
RANGE IN CHARACTERISTICS: Depth to acid sandstone, siltstone, or shale bedrock ranges from 4 to more than 20 feet. Reaction ranges from strongly to extremely acid. Depth to the fragipan ranges from 12 to 28 inches. Coarse fragments range from none to 5 percent in the Ap, Btg, and Btx horizons and from 0 to 35 percent in the Cg.
The Ap or A horizon has hue of 10YR, 2.5Y or 5Y, value of 4 to 6, and chroma of 2 or less, with redox features in shades of brown. Texture is silt loam.
The Btg horizon has hue of 5Y, 2.5Y or 10YR, value of 5 to 7, and chroma of 2 or less, with few to many redox features in shades of yellow, brown, red, olive or gray. Texture is silt loam or silty clay loam.
The Btx horizon has hue of 5Y, 2.5Y, or 10YR, value of 5 to 7, and chroma of 2 or less, with few to many redox features in shades of brown or yellow or has an evenly colored horizon in shades of brown, yellow, and gray. The upper part of the Btx horizon of some pedons has a few thin light gray or white silt coatings on prisms faces or as vertical seams. Texture is dominantly silt loam or silty clay loam; in the lower part of some pedons it is loam or clay loam.
The Cg horizon has hue of 5Y, 2.5Y, 10YR, or N/0, value of 5 to 7, and chroma of 2 or less, with redox features in shades of brown or yellow or is evenly colored in shades of brown, yellow, and gray. Texture is silt loam, silty clay loam, silty clay, loam, or clay loam, and is stratified in some pedons.
COMPETING SERIES: The Leonardtown is the only series in the same family. The Leonardtown soils have thinner sola essentially free of coarse fragments and have formed in a highly silty mantle underlain by Coastal Plain sediments.
GEOGRAPHIC SETTING: Mullins soils are on broad nearly level ridge tops and low stream terraces. Slopes range from 0 to 3 percent. These soils formed in old alluvium and residuum from acid siltstone, sandstone, and shale. Near the type location the mean annual temperature is 54.6 degrees F., and the mean annual precipitation is 47.3 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: The Johnsburg, Tilsit and Tyler, Atkins, Latham, Purdy, Shelocta, and Stendal series. The Atkins and Stendal soils on floodplains lack argillic horizons and fragipans, and the Atkins soils have more than 15 percent sand in the control section. Latham soils have clayey B horizons and a clay shale Cr at a depth of 20 to 40 inches, and are better drained. Purdy soils have clayey B horizons and lack fragipans. Shelocta soils lack fragipans and are well drained.
DRAINAGE AND PERMEABILITY: Poorly drained. Runoff is negligible to very slow. Permeability is moderate above the fragipan and slow to very slow in the fragipan.
USE AND VEGETATION: Most areas are cleared and in pasture or hay. Principal crop is corn, and some areas are idle. Native forest are bottomland oaks, hickory, and maple as the dominant species.
DISTRIBUTION AND EXTENT: The eastern mountains of Kentucky, some areas in the Western Coalfields of Kentucky, and possibly similar areas in Ohio, Tennessee, and West Virginia. The series is of small extent.
