Valentine soils.
Anselmo, Duda and Tassel soils are on similar landscape positions.
Anselmo soils are coarse-loamy.
Duda soils are moderately deep to sandstone.
Tassel soils are shallow to sandstone.
Doger and Dunday soils are in similar positions and are sandy throughout.
Hennings soils are on similar landscape positions and have a fine-loamy control section.
Ipage soils are lower on the landscape, do not have mollic epipedons, and are sandy throughout.
Simeon soils are on similar landscape positions and breaks, are sandy throughout and contain more than 35 percent medium and coarse sand in the C horizon.
Valentine soils do not have mollic epipedons, are sandy throughout and are on hummocks and dunes.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY:
Drainage: well drained
Runoff: very low to medium
Saturated Hydraulic Conductivity: high
USE AND VEGETATION: Most of this soil is in native grasses used for rangeland.
The remaining areas are used as cropland and most of the cropland is irrigated.
DISTRIBUTION AND EXTENT: Primarily north-central Nebraska. The series is of moderate extent.
