GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Cutcomb,
Elsmere,
Gus,
Loup,
Marlake,
Nenzel, and
Valentine soils.
Cutcomb soils are histosols.
Elsmere soils are slightly higher on swales on interdunes and are somewhat poorly drained having a seasonal zone of saturation or aquic conditions beginning at 46 centimeters (18 inches).
Gus soils are on similar swales and are fine-loamy in the particle size control section.
Marlake soils are in lower depressions on interdunes and are very poorly drained having a seasonal zone of saturation or aquic conditions beginning at the surface and having ponding up to 61 centimeters (24 inches).
Nenzel soils are higher on flats and hummocks on interdunes and are moderately well drained having a seasonal zone of saturation or aquic conditions beginning at 91 centimeters (36 inches).
Valentine soils are on higher dunes and are excessively drained having no seasonal zone of saturation or aquic conditions.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY:
Drainage: Poorly drained or very poorly drained
Runoff: negligent
Saturated Hydraulic Conductivity: high
Ponding frequency: frequent on the very poorly drained soil
Ponding duration: long on the very poorly drained soil with a depth of up to15 centimeters (6 inches)
USE AND VEGETATION: The major uses are livestock grazing and haying. The rangeland native plant community for the wet subirrigated ecological site (RO65XY023NE) is mostly big bluestem, prairie cordgrass, switchgrass, and yellow indiangrass; for the wetland ecological site (R065XY022NE) is mostly prairie cordgrass, northern reedgrass, sedge, rush, bluejoint, and slender wheatgrass.
DISTRIBUTION AND EXTENT: The Nebraska Sandhills in Nebraska and South Dakota (LRR G, MLRA 65). The series is of small extent.
