TURNERCREST SERIES


The Turnercrest soils consist of moderately deep, well drained soils formed in eolian or alluvium deposits and residuum derived from soft sandstone. They are on bedrock-controlled hills, fan remnants, ridges and structural benches. Slopes range from 0 to 30 percent. The average annual precipitation is about 12, and the mean annual air temperature is about 47 degrees F.

TAXONOMIC CLASS: Coarse-loamy, mixed, superactive, calcareous, mesic Ustic Torriorthents

TYPICAL PEDON: Turnercrest fine sandy loam-on a northeast facing hill footslope of 8 percent utilized as rangeland. (Colors are for dry soil unless otherwise stated)

A--0 to 2 inches; brown (10YR 5/3) fine sandy loam, very dark grayish brown (10YR 3/2) moist; weak fine granular structure; soft, very friable; many fine and very fine roots; slightly alkaline (pH 7.4); clear smooth boundary. (2 to 6 inches thick)

Bk1--2 to 6 inches; brown (10YR 5/3) fine sandy loam, brown (10YR 4/3) moist; weak medium and coarse subangular blocky structure; soft, friable; common fine and very fine roots; strongly effervescent; carbonates occurs in filaments and few masses; moderately alkaline (pH 8.2); gradual smooth boundary. (0 to 8 inches thick)

Bk2--6 to 25 inches; light gray (10YR 7/2) fine sandy loam, pale brown (10YR 6/3) moist; massive; slightly hard, very friable; few fine roots to 15 inches; strongly effervescent; carbonates disseminated and as few fine filaments; moderately alkaline (pH 8.2); clear wavy boundary. (15 to 32 inches thick)

Cr--25 inches; soft, light gray and very pale brown, calcareous sandstone.

TYPE LOCATION: Weston County, Wyoming; 1,980 feet west and 330 feet south of the NE corner of sec. 24, T. 44 N., R. 65 W.

RANGE IN CHARACTERISTICS: Depth to soft, calcareous sandstone ranges from 20 to 40 inches. These soils are typically calcareous throughout but may be leached as much as to 6 inches in some pedons. The soil is dry in the moisture control section more than half the time cumulative that the soil temperature at a depth of 20 inches is 41 degrees F. or warmer and is dry in all parts of the moisture control section for at least 60 consecutive days from July 15 to October 25 and for at least 90 cumulative days during this period. The mean annual soil temperature is 47 to 53 degrees F., and the soil temperature at a depth of 20 inches is 41 degrees F. or more for 175 to 192 days. The particle-size control section is fine sandy loam or sandy loam with 7 to 18 percent clay and 52 to 80 percent sand with more than 15 percent being fine sand or coarser. EC is 0 to 2 mmhos throughout the soil. Rock fragments may be present but break down on pretreatment and do not have lithic properties.

The A horizon has hue of 10YR or 2.5Y, value of 4 to 6 and 3 to 5 moist, and chroma of 2 to 4. Textures are loamy sand, loamy fine sand, fine sandy loam or sandy loam. Reaction is neutral to moderately alkaline.

The Bw horizon, where present, has hue of 10YR or 2.5Y, value of 5 or 6 and 3 to 5 moist, and chroma of 2 or 3. Depth to the base of the Bw horizon is less than 10 inches. Texture is fine sandy loam or sandy loam. Reaction is slightly alkaline or moderately alkaline.

The Bk has hue of 10YR or 2.5Y, value of 5 to 7 and 3 to 6 moist, and chroma of 2 or 3. Texture is fine sandy loam, very fine sandy loam or sandy loam. Reaction is slightly or moderately alkaline.

The C horizon, when present, has hue of 10YR or 2.5Y, value of 5 to 7 and 4 to 6 moist, and chroma of 2 to 4. Texture is fine sandy loam, very fine sandy loam or sandy loam. Some pedons have thin layers of loamy fine sand. Reaction is slightly alkaline or moderately alkaline.

The Cr horizon has a paralithic contact to soft, calcareous sandstone. The sandstone has hue of 10YR or 2.5Y.

COMPETING SERIES: These are the Cliff, Councelor, Gilston, Henrieville, Keeline, Nelman, Nelson, Oterodry, Shedado, Yarts and Zia series. Cliff, Councelor, Gilston, Henryville, Keeline, Oterodry, Uendal, Yarts and Zia soils are more than 60 inches deep. Nelman, Shedado and Uendal soils have a lithic contact to hard sandstone at 20 to 40 inches. Nelson soils are moist in some or all parts of the moisture control section for 60 consecutive days following July 15 and are moist in some parts for at least 90 cumulative days when the soil temperature at a depth of 20 inches is 41 F. or more. In addition, the Nelson soil also has a soil temperature warmer than 41 F. for 195 to 210 days.

GEOGRAPHIC SETTING: Turnercrest soils are on hills, ridges, fan remnants and structural benches. They formed in eolian or alluvium deposits and sandy residuum. Slopes are 0 to 30 percent. Elevations are 3,200 to 6,500 feet. The average annual precipitation is 10 to 15 inches with over half falling as snow or rain in April, May, and June and less than one inch falling in each month of July, August, September, and October. The mean annual air temperature is 45 to 53 degrees F. The frost-free season is 105 to 130 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Keeline soils and the Taluce, Tassel, Terro and Theedle soils. Taluce and Tassel soils have bedrock at less than 20 inches and the Terro soils have argillic horizons. Theedle soils have more than 18 percent clay in the particle size control section.

DRAINAGE AND PERMEABILITY: Well drained; very low to medium runoff depending on slope; moderately rapid permeability.

USE AND VEGETATION: These soils are used principally for grazing. Principal native vegetation is needleandthread, prairie sandreed, sand bluestem, western wheatgrass, and indian ricegrass.

DISTRIBUTION AND EXTENT: Central and east central Wyoming. The series is of small extent.
