LOCATION JUBIN INEstablished Series
The Jubin series consists of very deep, somewhat excessively drained soils on benches of hills. They formed in colluvium from sandstone and siltstone bedrock. Slopes range from 20 to 50 percent. Mean annual precipitation is about 43 inches, and mean annual temperature is about 54 degrees F.

Bw2--38 to 48 inches; yellowish brown (10YR 5/4) extremely bouldery fine sandy loam; moderate fine and medium subangular blocky structure; friable; common fine roots; 60 percent boulders and stones; 10 percent flagstones (sandstone); very strongly acid; gradual wavy boundary.
Bw3--48 to 60 inches; yellowish brown (10YR 5/4) extremely flaggy fine sandy loam; moderate fine and medium subangular blocky structure; friable; few fine roots; 60 percent flagstones; 10 percent channers (sandstone); very strongly acid; gradual wavy boundary.
Bw4--60 to 80 inches; brown (10YR 5/3) extremely flaggy fine sandy loam; moderate fine and medium subangular blocky structure; friable; few fine roots; 60 percent flagstones; 10 percent channers (sandstone); very strongly acid. (Combined thickness of the Bw horizons is more than 60 inches.)
TYPE LOCATION: Perry County, Indiana; 1,000 feet east and 2,750 feet south of the northwest corner, sec. 6, T. 4 S., R. 1 W. USGS Branchville, IN topographic quadrangle: lat. 38 degrees 11 minutes 57 seconds N. and long. 86 degrees 34 minutes 06 seconds W., NAD 27.
RANGE IN CHARACTERISTICS: The depth to the base of the cambic horizon is more than 80 inches. The particle-size control section averages 8 to 18 percent clay and 40 to 65 percent sand. Rock fragments are dominantly strongly cemented to indurated sandstone.
The A horizon has hue of 10YR, value of 3 or 4, and chroma of 1 to 3. Rock fragments are stones, boulders, channers, and flagstones, and average from 35 to 60 percent. The stones and boulders are the dominant sizes. Reaction ranges from strongly acid to slightly acid.
The BA horizon has hue of 10YR, value of 4 or 5, and chroma of 3 or 4. It is loam or fine sandy loam in the fine earth fraction. Rock fragments are stones, boulders, channers, and flagstones, and average from 35 to 90 percent. The flagstones, stones and boulders are the dominant sizes. Reaction ranges from very strongly acid to moderately acid.
The Bw, and BC horizon where present, has hue of 10YR, value of 4 or 5 and chroma of 3 or 4. It is loam or fine sandy loam in the fine earth fraction. Rock fragments are stones, boulders, channers, and flagstones, and average from 35 to 90 percent. The flagstones and channers are the dominant sizes. Reaction ranges from very strongly acid to moderately acid.

series. All these series except Greenlee, Highsplint,
Itswoot and Northcove have a solum thickness less than 80 inches. Greenlee soils formed in colluvium derived from granite, gneiss, and schist and contain rock fragments of such material, and are not dry in all parts of the soil moisture control section for more than 60 cumulative days. Highsplint and Itswoot soils average more than 35 percent silt in the lower part of the cambic horizon. Also, Itswoot soils are not dry in all parts of the soil moisture control section for more than 60 cumulative days. Northcove soils formed in colluvium derived from quartzite, phyllite, metasandstone, metagraywacke, and slate and contain rock fragments of such material.
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 52 to 57 degrees F, and the mean
annual precipitation ranges from 40 to 47 inches. Frost-free days range from 170 to 200.
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 PERMEABILITY: Somewhat excessively drained. Permeability is moderately rapid. 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 the west part of MLRA 120.
MLRA OFFICE RESPONSIBLE: Indianapolis, Indiana
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 24 inches (A and BA horizons); 2) Cambic horizon- the zone from 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.
