COMPETING SERIES: There are the Chew and Dean series.
GEOGRAPHIC SETTING:
Parent Material: weathered, buff colored, calcareous shale high in gypsiferous material
Landform: uplands
Slope: 1 to 10 percent
Mean annual temperature: 11 to 14 degrees C. (52 degrees to 57 degrees F.)
Mean annual precipitation: 30 to 38 centimeters (12 to 15 inches)
Frost free Period: 155 days
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Fort Collins, Narvey,
Stoneham and
Pultney soils.
Fort Collins and Stoneham soils have an argillic horizon.
Harvey soils have less than 40 percent carbonates.
Pultney soils have a paralithic contact at a depth of 20 to 40 inches.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY:
Drainage: well drained
Runoff: medium
Saturated Hydraulic Conductivity: moderately high or high
USE AND VEGETATION: This soil is used primarily for native grazing land and wheat production.
Native vegetation is Blue grama and galleta which dominate the rangeland.
DISTRIBUTION AND EXTENT: Southeastern Colorado. The series is moderately extensive.
