Bt4--59 to 75 inches; mottled olive yellow
(2.5Y 6/6), brownish yellow (10YR 6/6), dark red
(2.5YR 3/6), strong brown (7.5YR 5/6), light gray (2.5Y 7/0) clay; moderate fine and medium subangular blocky structure; firm; many distinct clay films on ped surfaces; less than 1 percent chert fragments, 1/4 to 3/4 inches in diameter; very strongly acid. (The combined thickness of the Bt horizon is 38 to 64 inches or more).
TYPE LOCATION: Hart County, Kentucky; 8 miles northeast of Munfordville, Kentucky 1.2 miles east of U.S. Highway 31-E, 2.2 miles south of Kentucky Highway 566, and 700 feet west of Knox Creek Road; on Canmer Quadrangle; Longitude 85o 45' 24" and Latitude 37o 18' 16".
RANGE IN CHARACTERISTICS: Thickness of solum and depth to bedrock are greater than 60 inches. Reaction is very strongly acid to neutral in the upper part of the solum and very strongly acid or strongly acid in the lower part. Rock fragments, mostly sandstone cobbles, angular chert gravel, or quartzitic pebbles range from 0 to about 15 percent.
The A horizon has hue of 10YR or 7.5YR, value of 4 to 6, and chroma of 3 or 4. Texture is loam or silt loam.
The BA horizon has hue of 7.5YR or 5YR, value or 4 or 5, chroma 4 to 8. Texture is silt loam, loam, clay loam, or sandy clay loam.
The upper part of the Bt horizon has hue of 5YR or 2.5YR, value 3 to 5, and chroma of 4 to 8 and most pedons have mottles in shades of brown, yellow or red. The middle and the lower parts of the Bt horizon have hue of 3.5Y to 2.5YR, value of 3 to 5, and chroma of 4 to 8. Most pedons have mottles in shades of brown, yellow, or red, and in shades of gray below a depth of 40 inches. Texture is silty clay loam, clay loam, sandy clay, silty clay or clay.
COMPETING SERIES: The Doniphan, Frederick, and Macedonia series are in the same family. Doniphan soils have more than 15 percent chert fragments in the control section. Frederick soils have more rock fragments in the A horizons that are mostly chert. The Macedonia soils have yellower hues, and residuum from clayey shales, and cherty dolomite or cherty limestone.
The Baxter, Christiana, Dewey, Dunmore, Fullerton, Hagerstown, Lodi, and Waynesboro soils are in related families. The Baxter and Hagerstown soils have base saturation more than 35 percent. Christiana and Dunmore soils have kaolinitic mineralogy. Dewey, Fullerton, and Waynesboro soils have thermic soil temperature regimes. Lodi soils have sola less than 60 inches thick.
GEOGRAPHIC SETTING: Canmer soils are on terraces, and uplands. Topography is dominantly rolling but ranges from undulating to steep. These soils have formed in old alluvium or unconsolidated material of sandstone, shale, and limestone origin. They are underlain by residuum of limestone origin. They are underlain by residuum of limestone or limestone bedrock below a depth of 5 feet. Slopes range from 2 to 30 percent. The mean annual temperature ranges from 53 to 57 degrees F, and the mean annual precipitation ranges from 45 to 55 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Frederick soils and the Allegheny, Elk, Nolichecky, and Riney soils. Allegheny, Nolichucky, and Riney soils have a fine-loamy particle size control section. Elk soils have less than 35 percent clay in the upper 20 inches of the argillic horizon.
DRAINAGE AND PERMEABILITY: Canmer soils are well drained. Runoff is slow to rapid and permeability is moderate.
USE AND VEGETATION: Most of the areas are used for pasture, hayland or woodland. Corn, tobacco, and alfalfa are grown on the less sloping areas. Native vegetation is mostly mixed hardwoods.
DISTRIBUTION AND EXTENT: Canmer soils are in south central Kentucky. The extent is small.
