COMPETING SERIES: This is the
Longford soils.
Longford soils have redder hue.
GEOGRAPHIC SETTING:
Parent material: silty loess
Landform: uplands
Slope: 0 to 17 percent
Mean annual temperature is from 10 to 13 degrees C (50 to 55 degrees F)
Mean annual precipitation: 56 to 71 centimeters (22 to 28 inches)
GEOGRAPHICALLY ASSOCIATED SOILS: These are
Butler,
Crete,
Holder,
Fillmore,
Hall,
Massie, and
Scott soils.
Butler, Fillmore, Massie, and Scott soils are saturated in the soil moisture control section for longer periods during the growing season.
Fillmore, Massie and Scott soils are in depressions on the landscape. Hall and Crete soils are pachic.
Hall soils are fine-silty and on stream terraces.
Holder soils are on uplands.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY:
Drainage: well drained
Runoff: low to moderate
Saturated hydraulic conductivity: moderately high
USE AND VEGETATION: Most areas are cultivated.
Common crops are corn, grain sorghum, winter wheat, soybeans, and alfalfa.
DISTRIBUTION AND EXTENT: South-central Nebraska and north-central Kansas. Hastings soils are extensive, totaling more than 1,000,000 acres.
MLRA OFFICE RESPONSIBLE: Salina, Kansas
SERIES ESTABLISHED: Adams County, Nebraska, 1923.
REMARKS: Diagnostic horizons and features recognized in this pedon:
Mollic epipedon: 0 to 51 centimeters (0 to 20 inches) (Ap and A horizons) Argillic horizon: 51 to 94 centimeters (20 to 37 inches) (Bt1 and Bt2 horizons)
Severely eroded Hastings soils no longer classify as Mollisols and will need to be recorrelated to a new series.
OSD Modification 2/2002RRZ: Added chroma of 1 to BA horizon; added to comment of the C horizon that Caco3 concretions are present
10/17/05 JCR
Changed to semi-tab format, added metric conversions and changed permeability to saturated hydraulic conductivity.
