RANGE IN CHARACTERISTICS:
Depth to the base of the cambic horizon: more than 203 cm (80 inches)
Particle-size control section: averages 8 to 18 percent clay and 40 to 65 percent sand
Rock fragments: dominantly strongly cemented to indurated sandstone
A horizon:
Hue: 10YR
Value: 3 or 4
Chroma: 1 to 3
Texture: loam or fine sandy loam in the fine earth fraction
Rock fragment content: averages 35 to 60 percent, including stones, boulders, channers, and flagstones, with the stones and boulders the dominant sizes
Reaction: strongly acid to slightly acid
BA horizon:
Hue: 10YR
Value: 4 or 5

Rock fragment content: averages 35 to 90 percent, including stones, boulders, channers, and flagstones, with the flagstones, stones and boulders the dominant sizes
Reaction: very strongly acid to moderately acid
Bw, and BC horizon where present:
Hue: 10YR
Value: 4 or 5
Chroma: 3 or 4
Texture: loam or fine sandy loam in the fine earth fraction.
Rock fragment content: averages 35 to 90 percent, including stones, boulders, channers, and flagstones, with the stones and boulders the dominant sizes in the upper part and the flagstones and channers the dominant sizes in the lower part
Reaction: very strongly acid to moderately acid
COMPETING SERIES: These are the Berks, Blasdell, Brownstown, Brownsville, Cadosia, Calvin, Cloverlick, Deadline, Highsplint, Judyville, Keyesville, Lippitt, Manlius, Matewan, Nailkeg, Peaks, Solon (T), Sylco, Warwick, and Wyoming series. All these series except Cloverlick and Highsplint have a solum thickness less than 80 inches. Cloverlick soils average less than 40 percent sand in the particle-size control section. Highsplint soils average more than 35 percent silt in the lower part of the cambic horizon. Also, Cloverlick and Highsplint soils are not dominated by bouldery and stony fragments in the upper part of the solum.
GEOGRAPHIC SETTING: Jubin soils are on benches of hills, at the base of Pennsylvanian age sandstone and siltstone bedrock escarpments. They formed in colluvium from sandstone and siltstone bedrock. Slopes range from 20 to 50 percent. Mean annual temperature ranges from 11.1 to 13.9 degrees C (52 to 57 degrees F), and the mean annual precipitation ranges from 1016 to 1168 mm (40 to 46 inches). Frost-free days range from 170 to 200. Elevation ranges from 105.2 to 305 meters (345 to 1000 feet) above mean sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Adyeville, Branchville, Deuchars, Ebal, Kitterman, and Tipsaw soils. The moderately deep, somewhat excessively drained Adyeville and Tipsaw soils are on backslopes of hills. The well drained Branchville soils are typically complexed with the Jubin soils and are on the lower part of the footslopes. The moderately well drained Deuchars, Ebal and Kitterman soils are on shoulders and backslopes of hills.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Somewhat excessively drained. Saturated hydraulic conductivity is high (14.11 to 42.34 micrometers/s). Permeability is moderately rapid (2 to 6 inches per hour). The potential for surface water runoff is medium.
USE AND VEGETATION: Most areas are used for woodland and wildlife habitat. Native vegetation is mixed, deciduous hardwood forest.
DISTRIBUTION AND EXTENT: Southern Indiana. The acreage is of small extent in MLRA 120B.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Morgantown, West Virginia
SERIES ESTABLISHED: Perry County, Indiana, 1997. The source of the name is from a stream in Perry County.
REMARKS: Diagnostic surface and subsurface horizons recognized in this pedon are:
1) Ochric epipedon- the zone from 0 to 61 cm (24 inches) - (A and BA horizons);
2) Cambic horizon- the zone from 61 to 203 cm (24 to 80 inches) - (Bw1, Bw2, Bw3, Bw4 horizons).
The Jubin soils were included in mapping with the Muskingum soils in the 1969 Perry Co., IN Soil Survey.
ADDITIONAL DATA: Lab data on pedon number S92IN-123-002 is at the NSSC, Lincoln, NE.
