OSAGE SERIES
The Osage series consist of very deep, poorly drained soils that formed in thick clayey alluvium on flood plains along major streams. Slope ranges from 0 to 2 percent. Mean annual precipitation is about 991 mm (39 inches), and mean annual temperature is about 16 degrees C (61 degrees F).
TAXONOMIC CLASS: Fine, smectitic, thermic Typic Epiaquerts

COMPETING SERIES: These are the
Carl,
Judice,
Laneburg, and
Terouge series. Carl soils have more than 7 percent rock fragments in the lower part of the series control section. Judice soils are in warmer climates that have mean annual air temperatures higher than 18 degrees C (65 degrees F). Laneburg soils are in wetter regions that have mean annual precipitation more than 1118 mm (44 inches). Terouge soils are less acidic in the upper part of the cambic horizon.
GEOGRAPHIC SETTING: Osage soils are on flood plains along major streams. Slope ranges from 0 to 2 percent. The soils formed in clayey alluvium.
Mean annual precipitation ranges from 965 to 1118 mm (38 to 44 inches). Mean annual air temperature ranges from 15 to 18 degrees C (59 to 65 degrees F). Elevation is 152 to 304 meters (495 to 1000 feet) above mean sea level. Thornthwaite Annual PE Index is greater than 64.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the coarser-textured
Cleora,
Hepler,
Lanton,
Mason, McCune,
Verdigris, and
Wynona soils and the lighter-colored
Lightning soils that are on nearby flood plains or low terraces.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Poorly drained. Depth to the top of an apparent seasonal high water table ranges from 15 to 46 cm (6 to 18 inches) between November and May in normal years. Saturated hydraulic conductivity is low. Permeability is very slow.
USE AND VEGETATION: Soils are used to grow crops. Principal crops are wheat, soybeans, and corn. Native vegetation is mostly tall grass prairie and in some locations deciduous hardwoods and understory of grasses.
DISTRIBUTION AND EXTENT: MLRAs 76, 112, and 116, and LRU 84A in southwestern Missouri, southeastern Kansas, and eastern Oklahoma. The type location is in MLRA 112. The series is extensive.
