The Ap horizon, in cultivated areas, has hue of 4 or 5 and chroma of 3 or 4. The A horizon is fine sandy loam or sandy loam with gravelly or stony phases. Coarse fragments by volume ranges from 0 to 25 percent.
The E horizon, where present, has hue of 10YR, value of 5, or 6 and chroma of 3 or 4. Texture is fine sandy loam or sandy loam with gravelly or stony phases. Coarse fragments by volume ranges from 0 to 25 percent.
The BA horizon has hue of 5YR, value of 4 or 5 and chroma of 6, or value of 5 and chroma of 8 or hue of 7.5YR, value of 5 and chroma of 6 or 8. It is fine sandy loam, sandy loam or sandy clay loam, with 0 to 10 percent by volume rock fragments.
The Bt1 and Bt2 horizons have hue of 2.5YR, value 4 or 5, and chroma of 6 or 8, or hue of 5YR, value of 5 and chroma of 6 or 8, or value of 4 and chroma of 8. In some pedons, the lower part has iron accumulations in shades of red or brown, or has hue of 7.5YR, value of 5, and chroma of 6 or 8, or hue of 10YR, value of 5 and chroma of 2 or 3. It is sandy clay or clay with 0 to 10 percent, by volume, rock fragments. Silt content is less than 20 percent. The Bt3 horizon has similar colors as the upper Bt horizon. It is sandy clay loam, sandy clay, gravelly sandy clay loam, or gravelly sandy clay and has 0 to 30 percent, by volume, rock fragments.
The C horizon has similar colors as the Bt horizon, or is variegated in shades of red or brown. It is sandy loam or sandy clay loam with 0 to 10 percent, by volume, sandstone fragments.
COMPETING SERIES: These are the Agnos, Braddock, Gassville, Groseclose, Howell, Monmouth, Muse, Sequoia, Trappist and Unison series. Agnos, Muse and Sequoia soils have siltier B horizons of silty clay or clay texture. In addition, Agnos soils have yellower colors. Braddock soils are over 60 inches deep to bedrock. Gassville soils have clay or cherty clay B horizons. Groseclose soils have sola 20 to 40 inches thick and have yellower colors. Howell and Monmouth soils have colors of 2.5Y or 5Y hue in the lower part of the B horizon. Trappist soils have bedrock at depths of 20 to 40 inches. Unison soils have silty clay loam or clay loam B horizons.
GEOGRAPHIC SETTING: Boden soils are on ridgetops and upland sideslopes. Slopes range from 1 to 20 percent. The soil formed in residuum weathered from sandstone and shale. Mean annual temperature ranges from 52 degrees to 59 degrees F; mean annual precipitation ranges from 42 to 50 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Agnos, Brockwell and Portia series. Brockwell soils are on similar landscapes and are coarse-loamy. Portia soils are on lower sideslopes and footslopes and have a fine-loamy control section.
DRAINAGE AND PERMEABILITY: Boden soils are well drained. Runoff is medium to rapid and permeability is moderately slow.
USE AND VEGETATION: Cleared areas are used to produce corn, oats, wheat, or for pasture. Woodland species are mainly red oak, hickory, and shortleaf pine.
DISTRIBUTION AND EXTENT: Ozark Highlands of Arkansas and Missouri. The series is of moderate extent.
