LOCATION WEOGUFKA ALEstablished Series
TAXONOMIC CLASS: Loamy-skeletal, mixed, semiactive, thermic, shallow Typic Hapludults
TYPICAL PEDON: Weogufka very channery sandy loam--on a convex southwest facing 33 percent slope in a wooded area.
(Colors are for moist soil unless otherwise stated.)
A--0 to 4 inches; dark yellowish brown (10YR 4/4) very channery sandy loam; weak fine granular structure; friable; many small and medium roots; about 40 percent coarse fragments of slate; strongly acid; clear smooth boundary. (1 to 5 inches thick)
Bt--4 to 10 inches; reddish brown (5YR 4/3) very channery loam; weak medium subangular blocky parting to weak fine subangular blocky structure; friable; discontinuous distinct clay films on faces of peds and around fragments; many small and medium roots; about 60 percent coarse fragments of slate; strongly acid; gradual wavy boundary. (5 to 9 inches thick)
Cr--10 to 28 inches; reddish brown (5YR 5/3) weathered slate with masses of Bt loam along fracture planes; about 95 percent coarse fragments; strongly acid; diffuse broken boundary.
R--28 inches; fractured tilted slate bedrock.
TYPE LOCATION: Shelby County, Alabama; about 3.5 miles south of Shelby, 1200 feet west and 300 feet north of the SE corner of sec. 17, T 24 N., R 15 E.
RANGE IN CHARACTERISTICS: Solum thickness and depth to a paralithic contact (Cr horizon) is 8 to 20 inches. Reaction ranges from moderately acid to very strongly acid, throughout. Content of rock fragments ranges from 10 to 50 percent in the A horizon, and from 35 to 90 percent in the Bt horizon.
The A horizon has hue of 5YR to 10YR, value of 3 through 5, and chroma of 1 through 4. It is sandy loam, loam, silt loam, with channery or very channery modifiers.
The Bt horizon has hue of 5YR to 10YR, value of 3 through 5, and chroma of 3 through 8. It is silt loam, loam, silty clay loam, and clay loam with very channery or extremely modifiers.
The Cr horizon consists of tilted, fractured, weathered phyllite, slate, or rarely schist. It is rippable to 4 or 5 feet with light machinery. Tongues of Bt material extend into the underlying material to depths of 4 feet along fracture planes.
The R horizon consists of tilted, fractured, hard phyllite, slate, or rarely schist. It is rippable to 4 or 5 feet with light machinery.
COMPETING SERIES: Sunlight series is the only soil in the same family. Competing series in similar families are Armuchee, Gorgas, Hector, Manteo, Montevallo, Mountainburg, Pickens, Sulphura, Talladega, and Tallapoosa soils. Sunlight soils formed in shaly siltstone or shale residuum. Armuchee soils have a clayey control section. Gorgas, Hector, Manteo, and Pickens soils have less coarse fragments. Hector, Manteo, Montevallo, Pickens, and Sulphura soils lack argillic horizons although Sulphura soils have a Bt horizon that is broken by rock in some part of the pedon. Talladega soils have a mean soil temperature of less than 59 degrees F. Tallapoosa soils have micaceous mineralogy.
GEOGRAPHIC SETTING: Weogufka soils are on ridgetops and convex side slopes that are in phyllite, slate, or rarely schist residuum of Carboniferous and Devonian ages. Slopes range from 10 to 60 percent. Mean annual precipitation is about 53 inches and mean annual temperature is about 62 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Fruithurst and Tatum series. These soils are deeper than 20 inches to Cr and have less than 35 percent fragments in the argillic horizon and are generally on lower positions of the landscape. In addition, Tatum soils have fine textured Bt horizons.
DRAINAGE AND PERMEABILITY: Well drained. Runoff is medium to rapid. Permeability is moderate.
USE AND VEGETATION: Native vegetation was oak-pine forest with Virginia pine being the dominant pine. Loblolly pine is commonly planted after native vegetation is harvested.
DISTRIBUTION AND EXTENT: In the metamorphic areas of Alabama and Georgia. Possibly in Tennessee. The series is of moderate
extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Raleigh, North Carolina
SERIES ESTABLISHED: Shelby County, Alabama, 1982.
REMARKS: Weogufka series would formerly have been classified in the Lithosol great soil group. It has been included in the Talladega and Tallapoosa series. The 8th Edition of the Keys to Soil Taxonomy changed subgroups for shallow families. Ochreptic (Inceptic) Hapludults may not be in shallow families.
