COMPETING SERIES: There are no other series in this family.
GEOGRAPHIC SETTING: Deible soils are on nearly level to gently sloping stream terraces and footslopes. They formed in either silty colluvium or loess and the underlying alluvium. Slopes are 0 to 5 percent. The mean annual temperature varies from about 54 to 57 degrees F, and the mean annual precipitation varies from about 35 to 45 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bearthicket, Higdon, Horsecreek, and Racoon soils. All of these soils have less clay in the particle size control section and are on slightly lower elevations.
DRAINAGE AND PERMEABILITY: Poorly drained. Runoff is typically high to very high, but is negligible in concave positions. Permeability is very slow and the saturated hydraulic conductivity is low. A seasonal high water table with an upper depth from 0 to 1 feet is present intermittently from December to May in most years.
USE AND VEGETATION: Most areas are used for cultivated crops or pasture. Native vegetation is mixed hardwoods.
DISTRIBUTION AND EXTENT: The Ozark Highland region (MLRA 116A) of southern Missouri. The series is of moderate extent.
