GEOGRAPHIC SETTING:
Parent material: coarse loamy material derived from colluvium
Landform: alluvial fans and footslopes
Slopes: 1 to 4 percent
Mean annual temperature: 52 to 57 degrees F
Mean annual precipitation: 34 to 40 inches

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Gymer, Konawa, Menoken(T), Morrill, Olmitz, Pawnee, Shelby series. The Gymer soils are red and occur on terraces. The Konawa soils are red and have a sandier surface. The Morrill soils formed in glacio-fluvial outwash and sit higher on the landscape. The Olmitz soils are fine-loamy and are on similar positions on the landscape. The Pawnee soils formed in clay till and are on higher positions on the landscape. The Shelby soils formed in fine-loamy till and are on higher positions on the landscape. The Menoken (T) soils are sandy and sit somewhat higher on the landscape.
DRAINAGE AND PERMEABILITY: Well drained. Surface runoff is low. Permeability is moderate.
USE AND VEGETATION: Native vegetation are woods and grasses. Now the soils are mainly cropped to corn, small grains, and soybeans.
DISTRIBUTION AND EXTENT: Northeastern Kansas, MLRA 106, Kansas River subset; Very limited extent.
MLRA OFFICE RESPONSIBLE: Salina, Kansas
SERIES PROPOSED: Shawnee County, Kansas, MLRA 106 soil survey area.
REMARKS: These soils were formerly mapped as Eudora sandy loam, sandy variant in Shawnee County, Kansas. Pedon used is 95KS177175. Lab data was run at the Kansas State University Pedology Laboratory in Manhattan, Kansas. Lab samples were SS958-963.
Diagnostic horizons and features recognized in this pedon are: mollic epipedon - the zone from the surface to a depth of 16 inches (Ap, A, Bw1 horizons); cambic horizon - the zone from 11 to 31 inches (Bw1, Bw2 horizons); Udic moisture regime-
Particle-size control section: The zone from 10 to 40 inches. ( A, Bw1, Bw2, BC horizons)
Mollic epipedon: The zone from 20 to 30 inches. (Ap, A horizons)
Cambic horizon: The zone from10 to 30 inches. (Bw1, Bw2 horizons)
