LOCATION EMBRY WYEstablished Series
TAXONOMIC CLASS: Coarse-loamy, mixed, superactive, nonacid, mesic Ustic Torriorthents
TYPICAL PEDON: Embry sandy loam, utilized as rangeland. (Colors are for dry soil unless otherwise stated)
A--0 to 6 inches; light brownish gray (10YR 6/2) sandy loam, dark grayish brown (10YR 4/2) moist; moderate fine granular structure; soft, very friable, nonsticky and nonplastic; slightly acid (pH 6.4); clear smooth boundary. (4 to 16 inches thick)
C1--6 to 23 inches; light brownish gray (10YR 6/2) sandy loam, dark grayish brown (10YR 4/2) moist; massive; slightly hard, very friable, nonsticky and nonplastic; few fine vesicular pores; neutral (pH 6.6); gradual wavy boundary.
C2--23 to 60 inches; pale brown (10YR 6/3) sandy loam, brown (10YR 4/3) moist; massive; slightly hard, very friable, nonsticky and nonplastic; neutral (pH 6.6).
TYPE LOCATION: Johnson County, Wyoming; 950 feet north and 610 feet east of the southwest corner of sec. 12, T. 42 N., R. 78 W.; Linch, Wyoming quadrangle. 43 degrees 37 minutes 7 seconds north latitude and 106 degrees 11 minutes 11 seconds west longitude.
RANGE IN CHARACTERISTICS: These soils are typically noncalcareous throughout, however some pedons may effervesce below a depth of 40 inches. Rock fragments range from 0 to 15 percent but are typically less than 5 percent and are mainly gravel size sandstone fragments. The control section is typically sandy loam but clay ranges from 5 to 18 percent, silt from 5 to 40 percent, and sand from 50 to 83 percent with more than 35 percent fine sand or coarser. The moisture control section is dry for 60 consecutive days and 90 cumulative days between July 15 and October 25. The mean annual soil temperature ranges from 47 degrees to 53 degrees F.
The A horizon has hue of 2.5Y to 7.5YR, value of 5 or 6 dry and 4 or 5 moist, and chroma of 1 to 4. This horizon is slightly acid to slightly alkaline.
The C horizon has hue of 2.5Y to 7.5YR, value of 5 to 7 dry and 4 to 6 moist, and chroma of 2 to 4. It is sandy loam or fine sandy loam. It is slightly acid to moderately alkaline.
COMPETING SERIES: This is the Florita series. The Florita series is not dry in the moisture control section for 60 or more consecutive days between July 15 and October 25.
GEOGRAPHIC SETTING: Embry soils are on alluvial fans, hills, dunes and terraces. Slopes are 0 to 20 percent. Elevation is 4200 to 6000 feet. These soils formed in alluvium and eolian deposits derived from noncalcareous sandstone. Annual precipitation ranges from 10 to 15 inches most of which falls as rain or snow in April, May, and June. The mean annual air temperature is 45 to 50 degrees F. The frost-free period is 110 to 130 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Clarkelon, Julesburg, Orpha and Taluce soils. Clarkelon soils have an irregular decrease in organic matter. Julesburg soils have argillic horizons and mollic epipedons. Orpha soils are in the sandy family. Taluce soils have a paralithic contact at 10 to 20 inches.
DRAINAGE AND PERMEABILITY: Well-drained; slow or medium runoff; moderately rapid permeability.
USE AND VEGETATION: These soils are used principally as rangeland and wildlife habitat. Some areas are used as irrigated hayland or pasture. The native vegetation is mainly needleandthread, prairie sandreed and Indian ricegrass.
DISTRIBUTION AND EXTENT: North-central Wyoming. The series is of small extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Denver, Colorado
SERIES ESTABLISHED: Johnson County (Southern Johnson Area), Wyoming, 1971.
REMARKS: Diagnostic horizons and features recognized in this pedon are: Ochric epipedon - the zone from the surface of the soil to a depth of 6 inches (A horizon).
