HOLDER SERIES
The Holder series consists of very deep, well drained soils formed in loess. Holder soils are on interfluves and hillslopes on loess uplands in the Central Loess Plains, MLRA 75. Slopes are typically less than 4 percent but ranges from 0 to 11 percent. Mean annual precipitation is about 711 millimeters (28 inches) and mean annual air temperature is about 11 degrees C (51 degrees F).
TAXONOMIC CLASS: Fine-silty, mixed, superactive, mesic Udic Argiustolls

COMPETING SERIES: These are the
Avans and

Avans soils allow for greater than 20 percent sand throughout the profile.
Geary soils have redder hues of 5YR or 7.5YR in the subsoil.
GEOGRAPHIC SETTING:

Butler,
Crete,
Fillmore, and
Hastings soils.
Butler soils are on flat or slightly concave uplands, have more clay in the argillic, and are somewhat poorly drained.
Crete soils are on similar landform positions but have a mollic epipedon greater than 50 cm thick and have more clay in the argillic.
Fillmore soils are in closed depressions, have an albic horizon, and are somewhat poorly drained.
Hastings soils are on similar landform positions but have more than 35 percent clay in the argillic.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY:
Drainage: well drained
Saturated hydraulic conductivity: moderately high
USE AND VEGETATION: Most areas are cropped and much of it is irrigated.
The main crops are corn, grain sorghum, winter wheat, soybeans, and alfalfa. The native vegetation consists of mixed tall, mid, and short grasses.
DISTRIBUTION AND EXTENT: East-central Nebraska and north-central Kansas; Land Resource Region H, Central Great Plains Winter Wheat and Range Region; Major Land Resource Regions 74, 75, and 76. The series is of large extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Denver, Colorado
SERIES ESTABLISHED: Howard County, Nebraska, 1970.
REMARKS: Diagnostic horizons and other features recognized in this pedon are:
Particle-size control section: The zone from 25 to 58 cm (10 to 23 inches) (the Bt horizons)
Mollic epipedon: The zone from 0 to 25 centimeters (0 to 10 inches) (the Ap and A horizons)
Argillic horizon: The zone from 25 to 58 centimeters (10 to 23 inches) (the Bt horizons)
An overblown phase is recognized for this soil that has a loam surface texture.
OSD Modification RRZ 7/2002; recognize a loam overblown phase 0 to 41 centimeters (0 to 16 inches) thick; dark buried horizons are possible; loam added to A horizon; Holder series were formerly included in the Holdrege series and were separated to include those with a udic-ustic moisture regime. Severely eroded Holder soils will no longer classify as Mollisols and need to be recorrelated to a new series.
