COMPETING SERIES:
These are the
Bon (SD),
Frazwell (AZ),
Humbarger (KS),
Lynx (AZ),
Manzano (NM),
Mauricanyon (CO),
Merrick (NE),
Pack (UT),
Shanta (NM),
St. Onge (SD), and
Umbarg (CO) series in the same family.
Bon soils are calcareous at depths of 15 to 50 centimeters (6 to 20 inches) and occur in cooler areas.
Frazwell soils occur in drier areas and have a stone line containing 40 to 55 percent rock fragments.
Humbarger soils have free carbonates above a depth of 40 centimeters (15 inches).
Lynx soils occur in drier areas.
Manzano soils occur in drier areas.
Maskell soils occur in cooler areas.
Mauricanyon soils occur in drier areas
Merrick soils occur in cooler and drier areas along the
Platte River in Nebraska.
Pack soils have redoximorphic features at depths less than 100 centimeters (40 inches).
Shanta soils average 5 to 20 percent rock fragments in the control section and occur in drier areas.
St. Onge soils are calcareous above a depth of 50 centimeters (20 inches) and occur in cooler areas.
Umbarg soils are calcareous throughout and occur in drier areas.
GEOGRAPHIC SETTING:
Parent Material: loamy alluvium
Landform: flood plains of river valleys
Slopes: 0 to 2 percent
Mean annual temperature: 13 to 14 degrees C (55 to 58 degrees F)
Mean annual precipitation: 55 to 80 centimeters (22 to 32 inches)
Thornthwaite Annual PE Index: 36 to 54
GEOGRAPHICALLY ASSOCIATED SOILS:
These are the
Farnum,
Shellabarger,
Waldeck and
Zenda soils.
The Farnum and Shellabarger soils are on adjacent uplands and have an argillic horizon.
The Zenda and Waldeck soils are somewhat poorly drained and have a water table above 100 centimeters (40 inches) for part of the year and are on slightly lower positions.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY:
Well drained. Runoff is low. Saturated hydraulic conductivity is moderately high. Permeability is moderate. Soils are rarely or occasionally flooded. Water table is generally below 180 centimeters (6 feet) except during periods of high stream flow.
USE AND VEGETATION: Mostly cultivated to wheat and sorghums. Native vegetation
is tall grasses.
DISTRIBUTION AND EXTENT: South-central Kansas; LRR H Great Plains Winter Wheat and Range, primarily MLRA 79 Great Bend Sand Plains; The series is moderately extensive.
