CHEROKEE SERIES


The Cherokee Series consists of very deep, somewhat poorly drained soils that formed in fine textured sediments of the Cherokee Prairies (MLRA 112). Cherokee soils are on terraces, upland benches or in head of drains. Slope ranges from 0 to 3 percent. The mean annual precipitation is about 1143 mm (45 inches), and the mean annual air temperature is about 14 degrees C (57 degrees F).

GEOGRAPHIC SETTING: Cherokee soils are on terraces, upland benches, or in head of drains on river valleys in the Cherokee Prairie. Slope ranges from 0 to 3 percent. The soils formed in eolian sediments and alluvium. Mean annual precipitation ranges from 889 to 1143 mm (35 to 45 inches). Mean annual temperature ranges from 14 to 18 degrees C (57 to 65 degrees F). Frost-free period is 190 to 210 days. Elevation is 215 to 355 meters (705 to 1165 feet) above mean sea level. Thornthwaites Annual P-E Index ranges from 64 to 80.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Barden, Dennis, Hepler, Lenna, Lightning, Medoc, Opolis, Parsons, and Taloka soils. Barden soils are moderately well drained, have thicker, dark colored surface horizons and are on ridges and side slopes on uplands. Dennis soils have thicker, dark colored surface horizons and are on summits, shoulders and side slopes. Hepler soils are commonly flooded, have less clay in the argillic horizon and have a thicker, dark colored surface horizon. Leanna soils have a mollic epipedon and are on flood plain steps. Lightning soils are commonly flooded and do not have an abrupt textural change and are on floodplains. Medoc soils have a brown subsoil within 75 cm of the soil surface and are on summits on uplands. Opolis soils are moderately well drained and are on summits and shoulders on uplands. Parsons soils have a mollic epipedon and are on summits on uplands and on paleoterraces. Taloka soils have a mollic epipedon and are on paleoterraces.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Somewhat poorly drained. Depth to the top of a perched seasonal high water table ranges from 25 to 51 cm (10 to 20 inches) between January and May in normal years. Potential for surface runoff is low. Saturated hydraulic conductivity is Low. Permeability is very slow.

USE AND VEGETATION: Mostly cultivated with sorghum, wheat, and soybeans the principal crops. Native vegetation is tall prairie grasses with a few deciduous trees, especially in the eastern extent of the series.

DISTRIBUTION AND EXTENT: MLRAs 112 and 116 in southeastern Kansas, northwestern Arkansas, southwestern Missouri, and northeastern Oklahoma. The type location is in MLRA 112. The series is moderately extensive.
