COMPETING SERIES: This is the
Hadar series in the same family.
Hadar soils have 2B and 2C horizons of loamy glacial till.
GEOGRAPHIC SETTING:
Parent materials - eolian sand deposited over loess
Landscape - upland
Landform - stream terrace
Slope - 0 to 11 percent
Mean annual air temperature - 8 to 11 degrees C,
Mean annual precipitation - 560 to 730 millimeters
GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing
Libory,
Loretto, and
Thurman soils; and the
Dunn,
Kenesaw,
Moody,
Nora,
Ortello, and
Valentine soils.
Libory soils are lower in the landscape and have redoximorphic concentrations in the 2B and 2C horizons.
Loretto soils are on similar landscapes and have an argillic horizon.
Thurman soils are higher in the landscape and are in the sandy family.
Dunn soils are lower in the landscape and are sandy over clayey.
Kenesaw soils are above Boelus soils in the landscape and are coarse-silty.
Moody and Nora soils are higher in the landscape and are fine-silty.
Ortello soils are on similar landscapes and are coarse-loamy.
Valentine soils are generally above Boelus soils in the landscape, lack a mollic epipedon, and are sandy (in the Psamments suborder).
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY:
Drainage class There are no redoximorphic features within 183 centimeters indicative of contemporary saturation or aquic conditions (well drained).
Saturated hydraulic conductivity - rapid in the sandy part and moderate in the silty part.
Runoff - slow or medium.
USE AND VEGETATION: Most of the acreage of this soil is cultivated and some areas are irrigated. Corn, grain sorghum, winter wheat, and alfalfa are the major crops. Where in native vegetation, the principal species are sand blue-stem, little bluestem, prairie sandreed, needleandthread, blue grama, and side-oats grama.
DISTRIBUTION AND EXTENT:
Physiographic Division - Interior Plains
Physiographic Province - Central Lowland
Physiographic Section - Dissected Till Plains
Land Resource Regions - Western Great Plains Range and Irrigated Region (LRR G), Central Great Plains Winter Wheat and Range Region (LRR H), and Central Feed Grains and Livestock Region (LRR M).
Major Land Resource Areas - Nebraska Sand Hills (MLRA 65), Dakota-Nebraska Eroded Tableland (MLRA 66), Central Nebraska Loess Hills (MLRA 71), and Loess Uplands (MLRA 102C).
The series is of moderate extent.
