LOCATION HEDVILLE KS+NEEstablished Series
TAXONOMIC CLASS: Loamy, mixed, superactive, mesic Lithic Haplustolls
TYPICAL PEDON: Hedville cobbly loam - in native grass. (Colors are for dry soil unless otherwise stated.)
A1--0 to 12 inches; dark grayish brown (10YR 4/2) cobbly loam, very dark brown (10YR 2/2) moist; moderate fine granular structure, upper 1 inch is very fine granular; slightly hard, very friable; many fine roots; many insect burrows and pores; 20 percent pebbles and angular cobbles of sandstone; slightly acid; gradual wavy boundary.
A2--12 to 16 inches; brown (7.5YR 4/2) cobbly loam, dark brown (7.5YR 3/2) moist; weak fine granular structure; slightly hard, very friable; many fine roots; many insect burrows; pebbles and angular cobblestones of weathered sandstone comprise 20 percent of soil mass; moderately acid; clear irregular boundary extending into cracks and pockets weathered into sandstone bedrock. (Combined thickness of the A horizon ranges from 4 to 19 inches.)
R--16 inches; brown sandstone.
TYPE LOCATION: Cloud County, Kansas; 5 miles west and 1/2 mile north of Miltonvale; 1940 feet north and 300 feet east of southwest corner, sec. 16, T. 8 S., R. 2 W.
RANGE IN CHARACTERISTICS:
Soil moisture: The soil moisture control section is Ustic moisture regime.
Depth to lithic contact: 4 to 19 inches to bedrock
Particle-size control section (weighted average):
Clay content: 8 to 22 percent
Sand content: 30 to 80 percent
Rock fragments: 5 to 35 percent by volume
Size: Cobbles or Stones
Kind: Sandstone
A horizon:
Hue: 10YR or 7.5YR
Value: 4 or 5 dry, 2 or 3 moist
Chroma: 1 to 3 dry or moist
Texture: Loam, sandy loam or fine sandy loam
Clay content: 8 to 22 percent
Rock fragments: 5 to 35 percent stones or cobbles
Reaction: Moderately acid to neutral
Bw or C horizons, if present:
Hue: 10YR, 7.5Y or 5YR
Value: 5 or 6 dry, 4 or 5 moist
Chroma: 2 to 4 dry or moist
Texture: Loam, sandy loam or fine sandy loam
Clay content: 8 to 22 percent
Rock fragments: 5 to 35 percent stones or cobbles
Reaction: Moderately acid to neutral
COMPETING SERIES: These are the
Apache,
Dalerose
Purner,
Santana,
Sogn, and
Venezia series.
Apache and Purner soils contain free carbonates above bedrock. Santana and Dalerose soils allow carbonates to the surface.
Venezia soils are drier in the soil moisture control section for longer periods. Sogn soils typically contain more clay and are underlain by limestone.
GEOGRAPHIC SETTING:
Parent material: Residumm derived from weathered, noncalcareous sandstone of the Dakota formation.
Landform: Uplands
Slopes: 3 to 30 percent
Mean annual temperature: 50 to 57 degrees F
Mean annual precipitation: 23 to 30 inches
Frost-free period: 150 to 190 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Crete, Edalgo, Hastings, Lancaster and Wells soils. Crete, Hastings, and Wells are very deep soils with an argillic horizon. Lancaster soils are moderately deep soils with an argillic horizon. Crete, and Hastings, soils are higher on the uplands. Edalgo soils have a clayey argillic horizon. Edalgo and Wells soils are on lower positions. Lancaster soils are on similar topographic positions as Hedville soils.
DRAINAGE AND PERMEABILITY:
Drainage: Somewhat excessive
Runoff: Medium and high
Permeability: Moderate above the bedrock
USE AND VEGETATION: Nearly all is in rangeland. Native vegetation is tall and mid grass prairie.
DISTRIBUTION AND EXTENT: In north-central Kansas, and south-central and southeastern Nebraska. The soils of this series are of large extent.
MLRA OFFICE RESPONSIBLE: Salina, Kansas
SERIES ESTABLISHED: Saline County, Kansas, 1952.
