USGS Ashby, Nebraska topographic quadrangle latitude 42 degrees, 14 minutes, 25 seconds North and longitude 101 degrees, 59 minutes, 55 seconds West.
RANGE IN CHARACTERISTICS:
Solum: 61 to 102 centimeters (24 to 40 inches) thick (commonly same depth to the 2C horizon)
Mollic epipedon: 61 to 91 centimeters (24 to 36 inches) thick
Free carbonates: at the surface of some but most pedons are noncalcareous
A horizon:
Hue: 10YR or 2.5Y
Value: 3 to 5, 2 or 3 moist
Chroma: 0 to 2
Texture: loam (includes sandy loam, fine sandy loam, sandy clay loam or clay loam)
Reaction: moderately acid to neutral (ranges to include slightly alkaline)
AC horizon in some pedons: similar in color and texture and ranges from 3 to 23 centimeters (1 to 9 inches) thick.
2Cg horizon:
Hue: 10YR or 2.5Y
Value: 5 to 7, 4 to 6 moist
Chroma: 0 to 2
Redoximorphic features: prominent or distinct
Texture: sand, fine sand, loamy sand, or loamy fine sand
Reaction: moderately acid to neutral.
COMPETING SERIES: There are no other series in the same family.
GEOGRAPHIC SETTING:
Parent material: loamy and sandy alluvium
Landform: interdunes in areas of the sandhills and on stream terraces
Slopes: 0 to 2 percent
Mean annual precipitation: 36 to 69 centimeters (14 to 27 inches)
Mean annual air temperature: 8 to 12 degrees C. (47 to 53 degrees F.)
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Cutcomb,
Elsmere,
Gus,
Loup,
Marlake,
Nenzel,
Valent and
Valentine soils.
Cutcomb soils formed in thick deposits of organic material.
Elsmere, Loup and Marlake soils are sandy throughout the particle size control section.
Elsmere and Loup soils have a mollic epipedon less than 61 centimeters (24 inches) thick.
Elsmere soils are higher on the landscape and have a lower seasonal water table.
Marlake soils are ponded for very long duration and are in interdunal depressions.
Gus soils are fine loamy in the particle size control section.
Nenzel soils have a seasonal high water table at depths between 3 and 5 feet and are higher on the landscape.
Valent and Valentine soils are sandy throughout the particle size control section and do not have a mollic epipedon.
Valent and Valentine soils are on dunes.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY:
Drainage: Poorly drained or very poorly drained
Runoff: very low or ponded
Saturated Hydraulic Conductivity: high
Seasonal high water table depth: very poorly drained soil +15 to 30 centimeters (+.5 to 1.0 foot) and poorly drained soil 0 to 46 centimeters (0 to 1.5 feet)
USE AND VEGETATION: These soils are in native grass.
These soils are used for hayland or range.
The native grasses on the poorly drained phase include big bluestem, indiangrass, prairie cordgrass, and switchgrass.
The native grasses on the very poorly drained phase include prairie cordgrass, reedgrasses, sedges and rushes.
DISTRIBUTION AND EXTENT: Nebraska sandhills and south-central South Dakota. The series is of small extent.
MLRA OFFICE RESPONSIBLE: Salina, Kansas
SERIES ESTABLISHED: Morrill County, Nebraska, 1911.
REMARKS: Diagnostic horizons and features recognized in this pedon are:
Mollic epipedon: 0 to 76 centimeters (0 to 30 inches) (A1 and A2 horizons)
Aquic soil conditions: saturated in the layer between 40 and 50 centimeters (16 to 20 inches) for at least a few days when the soil temperature is above biological zero (5 degrees C)
Endosaturation: saturated in all layers from the upper boundary of saturation to a depth of 200 centimeters or more from the mineral soil surface
Upper saturation boundary: less than 46 centimeters (1.5 feet) during late winter through spring in most years and over the surface in some places
Classification changed from Typic Haplaquolls to Cumulic Endoaquolls according to changes in Taxonomy in 1992.
