COMPETING SERIES: These are the Bearthicket, Cidermill, Elk, Elkinsville, Olephant, Parke, Pike, Tobinsport, Wellrock and Wellston series. Bearthicket soils average more than 5 percent sand in the particle-size control section and formed in silty alluvium. Cidermill soils have more than 5 percent rock fragments in the series control section, are less than 80 inches to the base of the argillic horizon and formed in silty material over glacial outwash. Elk soils typically average more than 5 percent sand in the argillic horizon, are less than 203 cm (80 inches) to the base of the argillic horizon and formed in mixed alluvium. Elkinsville soils average more than 5 percent sand in the argillic horizon, are less than 203 cm (80 inches) to the base of the argillic horizon and formed in less than 102 cm (40 inches) of loess over loamy alluvium. Olephant soils average more than 18 percent sand in the lower part of the series control section and formed in less than 183 cm (72 inches) of loess over a paleosol in lacustrine deposits. Parke and Pike soils average more than 45 percent sand in the lower part of the series control section and formed in less than 152 cm (60 inches) of loess over a paleosol in loamy outwash. Tobinsport soils average more than 65 percent sand in the lower part of the series control section and formed in less than 102 cm (40 inches) of loess over loamy and sandy materials. Wellrock and Wellston soils have a paralithic or lithic contact in the series control section and formed in less than 102 cm (40 inches) of loess over residuum from siltstone or sandstone.
GEOGRAPHIC SETTING: Rickert soils are on summits, shoulders and backslopes of loess hills. They formed in more than 203 cm (80 inches) of loess. 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 122 to 220 meters (400 to 720 feet) above mean sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Adyeville, Alford, Apalona, Ebal, Gatchel, Hosmer, and Wellston soils. The well drained, moderately deep, Adyeville soils are on backslopes of hills. The well drained, more permeable Alford soils are on similar landform positions of loess hills. The moderately well drained, fine-textured Ebal soils are on scarps, benches, and hills. The moderately well drained, less permeable Hosmer soils are on summits of hills. The well drained, deep Wellston soils are on scarps, benches, and hills.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained. Depth to an intermittent, perched water table is at 106 to 152 cm (3.5 to 5 feet) from December through April in most years. Saturated hydraulic conductivity is moderately high or high (4.23 to 14.11 micrometers/s) in the upper part of the solum and moderately high (1.41 to 4.23 micrometers/s) in the lower part. Permeability is moderate (0.6 to 2 inches per hour) in the upper part of the solum and moderately slow (0.2 to 0.6 inches per hour) in the lower part. The potential for surface water runoff is medium to high.
USE AND VEGETATION: Most gently sloping to moderately sloping areas are used to grow corn, soybeans, wheat and grass-legumes for hay and pasture. Most strongly sloping areas are in woodland and permanent pasture or wildlife habitat. Native vegetation is mixed, deciduous hardwood forest.
DISTRIBUTION AND EXTENT: Southern Indiana. The series is of small extent in MLRA 120B.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Morgantown, West Virginia
SERIES ESTABLISHED: Perry County, Indiana, 1995. The source of the name is from a named landmark in Perry County.
REMARKS: Diagnostic surface and subsurface horizons and features recognized in this pedon are:
1) Ochric epipedon- the zone from 0 to 20 cm (8 inches) - (Ap horizon); 2) Argillic horizon- the zone from 8 to 203 cm (8 to 80 inches) - (Bt1, Bt2, Bt3, Bt4, Bt5, Bt6, Bt7);
3) Redoximorphic depletions- the zone from 124 to 203 cm (49 to 80 inches).
This soil was included in mapping with the Alford soils in the 1969 Perry County soil survey.
