GEOGRAPHIC SETTING:
Landscape: river valleys
Landform: flood plains
Slopes: 0 to 2 percent
Elevation: 610 to 1067 meters (2000 to 3500 feet)

Mean annual precipitation: 43 to 61 centimeters (17 to 24 inches)
Frost-free period: 130 to 150 days
GEOGRAPHICALLY ASSOCIATED SOILS: This are the
Almeria,
Barney,
Calamus and
Inavale soils.
Almeria and Barney soils are lower on the landscape and have a seasonal high water table at less than 46 centimeters (1.5 feet).
Calamus soils are higher on the landscape and are coarser textured.
Inavale soils are higher on the landscape and have a seasonal high water table at below 183 centimeters (6 feet).
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY:
Drainage: somewhat poorly drained
Runoff: very low
Saturated hydraulic conductivity: very high
Seasonal high water table: 46 to 91 centimeters (1.5 feet to 3 feet).
Flooding: rarely to occasionally
USE AND VEGETATION: Most areas are in native grasses.
It is used for rangeland or hayland with limited acreage of alfalfa.
Native grasses are dominantly little bluestem, big bluestem, switchgrass, indiangrass and sedges.
DISTRIBUTION AND EXTENT: Bolent soils are of moderate extent in western Nebraska and possibly south central South Dakota.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Denver, Colorado
SERIES ESTABLISHED: Loup County, Nebraska, 1986.
REMARKS: Diagnostic horizons and other features recognized in this pedon are: Ochric epipedon: 0 to 13 centimeters (0 to 5 inches) (A horizon)
Aquic conditions: redox features in the matrix below 41 centimeters (16 inches)
Some areas of these soils have been included with Boel soils in the past. A horizons having values less than 5.5 dry and 3.5 moist are less than 7 inches thick.
