TYPE LOCATION: Ottawa County, Kansas; about 1 mile south and 6 miles west of Minneapolis; 1,300 feet south and 1,200 feet west of the northeast corner, sec. 13, T. 11 S., R. 5 W.

RANGE IN CHARACTERISTICS:
Soil moisture: The soil moisture control section is Ustic moisture regime bordering on Udic.
Depth to paralithic contact: 20 to 40 inches to shale.
Depth to argillic horizon: 8 to 24 inches
Thickness of the mollic epipedon: 8 to 18 inches
Some pedons lack a lithologic discontinuity.

Particle-size control section (weighted average):
Clay content: 27 to 65 percent
Sand content: 4 to 45 percent
Pararock fragments:
Content: 0 to 10 percent by volume
Size: 2mm to 3 inches
Kind: Sandstone and ironstone fragments

A horizon:
Hue: 7.5YR or 10YR
Value: 3 to 5 dry, 2 or 3 moist
Chroma: 1 or 2 dry or moist
Texture: Sandy clay loam, loam, silt loam, or silty clay loam.
Clay content: 15 to 37 percent
Reaction: Medium acid to neutral

2Bt horizon:
Hue: 7.5YR to 2.5Y
Value: 4 to 6 dry, 3 to 5 moist
Chroma: 2 to 4 dry or moist
Texture: silty clay, clay, silty clay loam, or clay loam
Clay content: 27 to 65 percent
Reaction: Medium acid to neutral

2C horizon:
Hue: 2.5YR to 2.5Y
Value: 4 to 7 dry, 3 to 6 moist
Chroma: 1 to 8 dry or moist
Texture: Silty clay, clay, silty clay loam, or clay loam.
Clay content: 27 to 65 percent
Reaction: Neutral to moderately alkaline
Concretions and soft accumulations of lime do not occur in all pedons.
Some pedons do not have C horizons.

COMPETING SERIES: These are the Benfield and Labette series.
Benfield soils contain free carbonate within the solum.
Labette soils have a lithic contact at a depth of 20 to 40 inches.

GEOGRAPHIC SETTING:
Parent material: Clay residumm weathered from noncalcareous shale
Landform: Uplands
Slopes: 1 to 40 percent
Mean annual temperature: 54 to 58 degrees F
Mean annual precipitation: 23 to 30 inches
Frost-free period: 150 to 180 days.
In many pedons, the upper part of the solum formed in colluvium from
sandstone, old alluvium or loess, or a mixture of these.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Geary, Hedville, Lancaster,
and Wells soils.
Geary soils have a fine-silty control section and occur on ridgetops and on
lower slopes.
Hedville and Lancaster soils are on upper slopes and ridgetops.
Hedville soils are underlain by sandstone and are loamy.
Lancaster soils are fine-loamy and are underlain by sandstone.
Wells soils are in similar positions as Edalgo soils. Wells soils are deep
and fine-loamy.

DRAINAGE AND PERMEABILITY:
Drainage: Well
Runoff: Medium or very high
Permeability: Very slow

USE AND VEGETATION: Most areas are used for rangeland with some of the gentler slopes cultivated to wheat and grain sorghum. Native vegetation is tall grass prairie species.

DISTRIBUTION AND EXTENT: North central Kansas and adjacent areas in Nebraska. The Edalgo series is moderately extensive.

MLRA OFFICE RESPONSIBLE: Salina, Kansas

SERIES ESTABLISHED: Saline County, Kansas, 1952.

REMARKS:
Diagnostic horizons and features recognized in this pedon are:
Particle-size control section: The zone from 12 to 21 inches. (2Bt horizons)
Mollic epipedon: The zone from 0 to 12 inches. (A and BA horizons) Argillic horizon: The zone from 12 to 21 inches. (2Bt horizons)
Paralithic contact: The contact with shale at 20 inches. 40 (2Cr horizons)
Lithologic discontinuity: At the upper boundary of the 2Bt horizon.
Other features: The mottles with chroma of 2 or less are inherited from the
shale, and are not considered an indication of wetness.
