COLLINSVILLE SERIES

The Collinsville series consists of very shallow and shallow, well drained to somewhat excessively drained, soils that formed in residuum weathered from sandstone of Pennsylvania age on interfluves and hillslopes. Slope ranges from 1 to 35 percent. Mean annual precipitation is about 1015 mm (40 inches) and mean annual air temperature is 16 degrees C (61 degrees F).

TAXONOMIC CLASS: Loamy, siliceous, superactive, thermic Lithic Hapludolls

TYPICAL PEDON: Collinsville fine sandy loam in a Bates-Collinsville complex, 3 to 8 percent slopes in rangeland on the backslope of an interfluve, at an elevation of 232 meters (760 feet) above mean sea level. Colors are for moist soil unless otherwise stated.)

A--0 to 18 cm (0 to 7 inches); very dark grayish brown (10YR 3/2) fine sandy loam, dark grayish brown (10YR 4/2) dry; moderate medium granular structure; slightly hard, very friable; moderately acid; gradual wavy boundary. [10 to 36 cm (4 to 14 inches) thick]

C--18 to 23 cm (7 to 9 inches); brown (10YR 4/3) fine sandy loam, brown (10YR 5/3) dry; massive; slightly hard, very friable; 40 percent soft and hard fragments of sandstone by volume; moderately acid abrupt wavy boundary. [0 to 15 cm (0 to 6 inches) thick]

R--23 to 51 cm (9 to 20 inches); yellowish brown sandstone; hard; fractured at intervals from 30 to 91 cm (12 to 36 inches) with small amount of soil material in the cracks.

TYPE LOCATION: Rogers County, Oklahoma; about 2 miles north and 1.5 miles east of Inola; 1,000 feet east and 45 feet south of the northwest corner of sec. 27, T. 20 N., R. 17 E; USGS Choteau NW, Oklahoma topographic quadrangle; lat. 36.191000 degrees and long. -95.491000 degrees; WGS84.

RANGE IN CHARACTERISTICS: Depth to lithic contact with sandstone bedrock ranges from 10 to 50 cm (4 to 20 inches). The weighted average content of coarse fragments in the control section is less than 35 percent.

The R layer is brownish hard sandstone that cannot be augered. The sandstone does not break down upon overnight shaking in calgon.

COMPETING SERIES: There are no competing series.

GEOGRAPHIC SETTING: Collinsville soils are on interfluves and hillslopes on plains. Slope ranges from 1 and 35 percent. They formed in residuum weathered from sandstone of Pennsylvanian age. Mean annual precipitation ranges from about 800 to 1200 mm (31 to 47 inches). Mean annual air temperature ranges from 14 to 17 degrees C (57 to 62 degrees F). Frost free days range from 170 to 255. Elevation is 155 to 360 meters (505 to 1180 feet). Thornthwaite annual P-E indices range from 64 to 80.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Barco, Barden, Bates, Choteau, Dennis, Eram, and Talihina series. Barco, Barden, Bates, Choteau, Dennis and Eram soils have a solum thickness of more than 51 cm (20 inches) and have an argillic horizon. Talihina soils are clayey and formed in residuum weathered from shale.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained to somewhat excessively drained; Potential for surface runoff is medium to very high. Saturated hydraulic conductivity is high (14 to 42 micrometers per second). Permeability is moderately rapid.

USE AND VEGETATION: The soil is used mainly for native range. Small amounts are used for tame pasture on non-stony phases. The native vegetation is tall grass prairie.

DISTRIBUTION AND EXTENT: MLRAs 84A, 112, 118A, and 118B in Oklahoma, Kansas, and Missouri. The series is extensive.

SOIL SURVEY REGIONAL OFFICE (SSRO) RESPONSIBLE: Indianapolis, Indiana

SERIES ESTABLISHED: Tulsa County, Oklahoma; 1935.

REMARKS: Data on mineralogy are lacking, but data for the related and associated Bates soil has siliceous mineralogy.

Diagnostic horizons and features recognized in this soil are:
Mollic epipedon - the zone from the surface of the soil to a depth of 18 cm (7 inches) (the A horizon).
Lithic contact - hard sandstone bedrock at a depth of 23 cm (9 inches) (the R layer).
Moisture Regime - Udic

5/25/00:PRF- modified classification to include superactive.
