GEOGRAPHICALLY ASSOCIATED SOILS: These are the Butler, Geary, Judson,<br />

Mayberry, Pawnee and Yutan soils.<br />

Butler soils are somewhat poorly drained and form a drainage sequence with the Aksarben soils<br />

and commonly are in the swale parts of the landscape.<br />

Judson soils are on footslopes and formed in local colluvium.<br />

Mayberry soils are on adjoining lower parts of the landscape. They formed in till or in paleosols<br />

formed in till.<br />

Pawnee soils are on adjoining lower parts of the landscape. They formed in till or in paleosols<br />

formed in till.<br />

Yutan soils have mollic colors less than 10 inches thick, average less clay in the particle size<br />

control section and are on shoulders and backslopes.<br />

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY:<br />

Drainage: Well drained.<br />

Surface runoff: Low to moderately high.<br />

Saturated hydraulic conductivity: Moderately low<br />

USE AND VEGETATION: Most areas are cultivated.<br />

The main crops are corn, soybeans, small grains and grain sorghum.<br />

Native vegetation is tall prairie grasses.<br />

DISTRIBUTION AND EXTENT: Southeastern <strong>Nebraska</strong> and northeastern Kansas. LRR 5,<br />

MLRA 106. They are extensive.<br />

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Salina, Kansas<br />

SERIES ESTABLISHED: Brown County, Kansas, 1994.<br />

REMARKS: Diagnostic horizons and features recognized in this pedon are:<br />

Particle-size control section: 30 to 80 centimeters. (Bt1, Bt2, and Bt3 horizons)<br />

Mollic epipedon: 0 to 46 centimeters. (Ap, A, and Bt1 horizons)<br />

Argillic horizon: 30 to 107 centimeters. (Bt1, Bt2, Bt3, and Bt4 horizons)<br />

Redoximorphic concentrations (relict): 46 to 203 centimeters. (Bt2, Bt3, Bt4, BC, and C<br />

horizons)<br />

Moisture regime: Udic<br />

These soils were previously mapped as Sharpsburg soils. The Sharpsburg soils are moderately<br />

well drained and have a perched water table at a depth of 1.2 to 1.8 meters.<br />

CL 6/30/2008 Removed the term mottling from the OSD and replaced with redox or<br />

redoximorphic features. All SE units were removed.<br />
