LOCATION BINTON WYEstablished Series
TAXONOMIC CLASS: Fine-loamy, mixed, superactive, calcareous, mesic Typic Torrifluvents
TYPICAL PEDON: Binton clay loam-rangeland. (Colors are for dry soil unless otherwise stated.)
A--0 to 6 inches; pale brown (10YR 6/3) light clay loam, dark brown (10YR 4/3) moist; moderate fine granular structure; soft, very friable, slightly sticky and slightly plastic; strongly effervescent; very strongly alkaline (pH 9.2); clear smooth boundary. (0 to 8 inches thick)
C--6 to 60 inches; pale brown (10YR 6/3) stratified very fine sandy loam, clay loam, and silty clay loam, dark brown (10YR 3/3) moist; massive with strata ranging from 1 to 6 inches in thickness; slightly hard, very friable, slightly sticky and sticky and slightly plastic and plastic; strongly effervescent; very strongly alkaline (pH 9.2).
TYPE LOCATION: Fremont County, Wyoming; SW1/4 of sec. 14, T. 3 N., R. 1 W.
RANGE IN CHARACTERISTICS: Exchangeable sodium percentage ranges from 15 to 60 percent throughout the control section. The soils are typically calcareous throughout but may be leached in some pedons for a few inches. Calcium carbonate equivalent of the control section ranges from 2 to 15 percent and is variable from strata to strata. The mean annual soil temperature is 48 to 51 degrees F., and the mean annual summer soil temperature is 59 to 63 degrees F. The particle size control section is highly stratified and averages loam, clay loam, or silty clay loam with 18 to 35 percent clay, 40 to 70 percent silt, and 15 to 35 percent sand with more than 15 percent fine sand or coarser. Rock fragment content of the particle size control section is typically less than 5 percent but may range from 0 to 15 percent fine gravel. EC of the entire soil ranges from 2 to 8 mmhos.
The A horizon, when present, has hue of 5Y through 7.5YR, value of 5 through 7 dry, 4 through 6 moist, and chroma of 2 through 6 dry and moist. Reaction is strongly alkaline or very strongly alkaline.
The highly stratified C horizon has hue of 5Y through 7.5YR, value of 5 through 7 dry, 4 or 5 moist, and chroma of 2 through 4 dry and moist. Reaction of the entire matrix is strongly alkaline or very strongly alkaline, but individual strata containing salt may be buffered to moderately alkaline.
COMPETING SERIES: These are the Boysen, Jocity, Lostwells, Toddler, and Youngston series. Boysen soils have more than 35 percent fine and coarser sand in the particle size control section. The Jocity, Lostwells, and Youngston soils have less than 15 percent exchangeable sodium throughout. The Toddler soils contain 15 to 40 percent calcium carbonate equivalent.
GEOGRAPHIC SETTING: Binton soils are on nearly level to gently sloping alluvial terraces or fans along flood plains. Slopes are 0 to 6 percent. These soils formed in alluvium of varying textures from calcareous sodic sandstone and shale. Elevation ranges from 3,800 to 5,500 feet. The mean annual precipitation is about 8 inches but ranges from 6 to 10 inches with over half falling as snow and rain in April, May, and June. The mean annual temperature ranges from 43 to 47 degrees F. The frost-free season is estimated to range from 110 days to 125 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Boysen, Lostwells, and Youngston soils. They all occupy similar physiographic positions.
DRAINAGE AND PERMEABILITY: Well drained; medium or slow runoff; slow permeability.
USE AND VEGETATION: Most areas of Binton soils are utilized as rangeland and wildlife habitat. Native vegetation is greasewood, Gardner saltbush, snakeweed, bottlebrush squirreltail, and Indian ricegrass.
DISTRIBUTION AND EXTENT: West-central and northwestern Wyoming. The series is of moderate extent.

REMARKS:
The superactive cation exchange activity class was added in 03/2003 to the taxonomic classification by the National Soil Survey Center on request of the Reno MLRA office, without review of the soil series property data. The remainder of this document has not been updated.
