COMPETING SERIES: There are no other series in the same family.
GEOGRAPHIC SETTING:
Parent material: eolian sands deposited over loamy and sandy alluvium
Landform: high flood plains
Mean annual precipitation: 36 to 46 centimeters (14 to 18 inches)
Mean annual temperature: 8 to 12 degrees C. (47 to 53 degrees F.)
GEOGRAPHICALLY ASSOCIATED SOILS: These include
Jankosh,
Lewellen,
McCuligan,
Rushcreek and
Scoville soils.
Jankosh and Lewellen soils are lower on the landscape, have a higher seasonal water table and are strongly alkaline.
McCuligan soils have a higher seasonal water table, are lower on the landscape and are shallow over coarse sand.
Rushcreek soils are fine loamy, have a mollic epipedon and are on similar landscapes.
Scoville soils are on stream terraces and typically are sandy in the upper 40 inches of the series control section.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY:
Drainage: moderately well drained
Runoff: low
Saturated hydraulic conductivity: moderately high to high
Seasonal high water table depth: 0.9 to 1.8 meters (3 to 6 feet)
USE AND VEGETATION: Most of the acreage is used for irrigated cropland.
Common crops are corn and alfalfa.
Most areas have been land leveled for gravity irrigation.
DISTRIBUTION AND EXTENT: Western Nebraska. The series is not extensive.
