RANGE IN CHARACTERISTICS: Solum thickness ranges from 25 to 50 inches. Depth to limestone bedrock ranges from 40 to 60 inches. Reaction ranges from slightly acid to slightly alkaline in the A, E, and Bt horizons and from slightly alkaline to moderately alkaline in the BC and C horizons.
The A or Ap horizon has hue of 10YR, 2.5Y, or 5Y value of 3 to 5, and chroma of 1 to 4; or it is neutral with value of 3 or 4, and chroma of 0. Texture is loam, sandy loam, fine sandy loam, or clay loam.
The E horizon, where present, has hue of 10YR or 2.5YR, value of 5 or 6, and chroma of 2 or 3. Texture is fine sandy loam, loam, clay loam, or silty clay loam.
The upper part of the Bt horizon has hue of 7.5YR to 2.5Y, value of 4 to 6, and chroma of 3 to 8. Redoximorphic features in shades of yellow, brown, gray, and red range from few to many. Texture is silty clay, clay loam, or clay.
The lower part of the Bt horizon has hue of 7.5YR to 5Y, value of 5 to 7, and chroma of 1 or 6; or there is no dominant color and is multicolored in shades of yellow brown, gray and red. Redoximorphic features in shades of brown, yellow, and gray range from common to many. Texture is silty clay loam, silty clay, clay loam, or clay.
The BC and C horizons have hue of 10YR to 5Y, value of 5 to 7, and chroma of 1 or 2; or there is no dominant color and it is multicolored in shades of yellow, red, brown, and gray. Masses of iron accumulation in shades of brown and yellow range from few to many. Limestone concretions and soft masses of calcium carbonate range from few to many. Texture is silty clay loam, silty clay, clay loam or clay.
The Cr horizon, where present, is composed of soft limestone that is easily dug with hand tools. Hard limestone fragments up to boulder-size range from none to common.
The R horizon is composed of limestone that is rippable by power equipment. Hard limestone fragments up to boulder-size range from few to many. Solution holes up to 6 inches in diameter are filled with material from the overlying horizons and extending to a depth of 60 inches or more range from few to many.
COMPETING SERIES: These are the Chickasaw, Colbert, Etoile, Iota, Kellison, Oakhurst, Oula, Rayburn, and Woodtell in the same family. The well drained Chickasaw are more acid and are underlain by sandstone and claystone. The moderately well drained Colbert soils are underlain by argillaceous limestone and shale are in the southern Appalachian limestone ridges and valleys. The moderately well drained Etoile soils and well drained Kellison soils are underlain by tertiary age shale of the Cook Mountain Geologic Formation in Texas. The well drained Iota soils are very deep and are on stream terraces. The moderately well drained Oakhurst soils are very deep to unconsolidated volcanic tuffaceous material that overlies siltstone and sandstone strata. The well drained Oula soils are very deep and in the tertiary age Catahoula Formation. The moderately well drained Rayburn soils formed in acid tuffaceous sandstone. The well drained Woodtell soils formed in Eocene Age shale in the Wilcox and Cook Mountain Formations in Texas, Oklahoma and Louisiana.
GEOGRAPHIC SETTING: Telogia soils formed in clayey sediments that weathered from limestone of the Hawthorn Formation lower slopes of uplands. Slopes range from 0 to 8 percent. The climate is warm and humid. Near the type location, the mean annual temperature ranges from 61 to 65 degrees F., and the mean annual precipitation ranges from 50 to 55 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are Bonifay, Cowarts, Dothan, Fuquay, Hardin Heights; Nankin and Orangeburg soils. All of these soils are on higher adjacent positions, are very deep, do not have smectitic mineralogy, and are not underlain by limestone, with the exception of Hardin Heights. The well drained Bonifay soils have sandy surface and subsurface layers 40 to 80 inches thick and have plinthite in the subsoil. The well drained and moderately well drained Cowarts soils have fine-loamy control sections. The well drained Dothan soils have fine-loamy control sections and are Plinthic. The well drained Fuquay soils have sandy surface and subsurface layers 20 to 40 inches thick, have loamy control sections, and are Plinthic. The well drained Hardin Heights soils are shallow to limestone. The moderately well drained Nankin soils have less clay in the control section. The well drained Orangeburg soils have fine-loamy control sections.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained; very slow permeability.
USE AND VEGETATION: Most areas of Telogia soils are in woodland and used for forest production and wildlife habitat. The vegetation consists of Palmetto, Sweet Bay, Red maple, Wax myrtle and Sweet gum.
DISTRIBUTION AND EXTENT: Small limestone outcrops in the Florida panhandle. The series is of minor extent.
