LANGDON SERIES

The Langdon series consists of very deep, somewhat excessively drained, rapidly permeable soils that formed in sandy eolian sediments. These soils are on undulating to rolling dunes on paleo-terraces in river valleys of the Great Bend Sand Plains (MLRA 79). Slopes are complex and range from 1 to 15 percent. Mean annual precipitation is 29 inches (74 centimeters) and mean annual temperature is 56 degrees F (13 degrees C).

TAXONOMIC CLASS: Mixed, mesic Lamellic Ustipsamments

GEOGRAPHIC SETTING: Langdon soils

Parent material: sandy eolian sediments
Landform: undulating to rolling dunes on paleo-terraces
Slopes: 1 to 15 percent
Elevation: 1525 to 1790 feet (464.8 to 545.6 meters)
Mean annual air temperature: 55 to 57 degrees F (13 to 14 degrees C)

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Carway , Carbika , Dillhut , Pratt, Solvay , Spelvin , Tivin , Turon and Warnut series. The wetter, poorly drained and fine textured Carbika and loamy textured Warnut soils are in nearby depressions. The wetter, somewhat poorly drained, loamy textured Carway soils are in nearby depressions. Dillhut soils are moderately well to somewhat poorly drained, and have a loamy buried soil between 20 and 40 inches (50 to 102 centimeters). Solvay soils have a fine-loamy argillic horizon and are somewhat poorly drained. Dillhut and Solvay soils are in interdunes. Pratt and Turon soils have a sandy argillic horizon which has both more and thicker lamellae. They are on lower sideslopes and undulating areas. Tivin soils do not have lamellae above 80 inches (203 centimeters) and are on similar positions.

DRAINAGE AND PERMEABILITY: Langdon soils are somewhat excessively drained. Runoff is very low to low, and permeability is rapid.

USE AND VEGETATION: Used mainly for grazing beef cattle. Native vegetation is sand bluestem, sand dropseed, and prairie sandreed.

DISTRIBUTION AND EXTENT: South Central Kansas. LRR H Great Plains Winter Wheat and Range, MLRA 79 Great Bend Sand Plains. The series is of moderate extent.

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Denver, Colorado

SERIES ESTABLISHED: Reno County, Kansas, 1994.

REMARKS: Diagnostic horizons and features recognized in this pedon are:

ochric epipedon: The zone from 0 to 8 inches (0 to 20 centimeters). (A)
Lamellae in the E&Bt horizon are too few and too thin to constitute an argillic horizon.
Keys to Soil Taxonomy: Eighth edition, 1998

ADDITIONAL DATA: This series was formerly mapped as the Tivoli series.
