LOCATION TIPPERARY WY+CO MT NV UTEstablished Series
TAXONOMIC CLASS: Mixed, mesic Typic Torripsamments
TYPICAL PEDON: Tipperary loamy sand - native grassland (Colors are for dry soil unless otherwise stated.)
A--0 to 5 inches; light brownish gray (10YR 6/2) loamy sand, grayish brown (10YR 5/2) moist; single grained; loose; common fine and very fine roots; effervescent; 5 percent gravel; moderately alkaline (pH 8.2); gradual wavy boundary. (4 to 6 inches thick)
Bk--5 to 60 inches; light brownish gray (10YR 6/2) sand, grayish brown (10YR 5/2) moist; single grained; loose; effervescent; calcium carbonate disseminated and as few soft masses and seams; 5 percent gravel; moderately alkaline (pH 8.4).
TYPE LOCATION: Fremont County, Wyoming; 1320 feet west of the SE corner of Sec. 23, T4N, R4E. Mexican Pass SE quadrangle 43 degrees 18 minutes 8 seconds north latitude and 108 degrees 21 minutes 55 seconds west longitude.
RANGE IN CHARACTERISTICS: These soils are usually dry. They are moist in the moisture control section in April, May and early June. These soils typically effervesce at or near the surface but they may be leached of calcium carbonate as deep as 10 inches in some pedons. The content of organic carbon ranges from .05 to 1 percent in the surface horizon and decreases uniformly with depth. Electrical conductivity is typically less than 2 millimho/cm and exchangeable sodium percentage ranges from less than 1 to 10 percent throughout. The particle size control section ranges from sand to loamy fine sand with strata of coarse sand in some pedons. Content of rock fragments ranges from 0 to 15 percent but is typically less than 5 percent. Mean annual soil temperature ranges from 47 degrees to 53 degrees F. and mean summer soil temperature from 60 degrees to 68 degrees F.
The A horizon has hue of 2.5Y through 7.5YR, value of 6 or 7 dry, 4 or 5 moist, and chroma of 2 through 6. The A horizon is moderately to strongly alkaline. Usually it is single grain, but is weak granular in some pedons. It is loose or soft when dry.
The Bk or Ck horizon has hue of 2.5Y through 7.5YR value of 6 through 8 dry, 5 or 6 moist, and chroma of 2 through 6. This horizon is moderately to strongly alkaline. Calcium carbonate equivalent typically ranges from less than 1 to 5 percent but some areas may have inconsistent layers with up to 10 percent.
COMPETING SERIES: These are the Als, Ecklund, Hawsley, Isolde, Kawich, Kewake, Razito, Sheppard, Stumble, Sundown, Tipper, Tricera, and Yenrab series. Als soils are non-effervescent. Ecklund soils have a lithic contact at 40 to 60 inches. Hawsley, Isolde, and Tricera soils effervesce at depths greater than 10 inches. Kawich soils formed in pyroclastic material. Kewake soils contain 5 to 30 percent sand sized pumice. Razito soils are intermittently moist is some part of the moisture control section from August to October. Sheppard soils have hue of 5YR or redder. Stumble soils have more than 15 percent rock fragments and have a high proportion of volcanic ash, pumice, and pyroclastics. Sundown soils have very strongly alkaline lower C horizons between depths of 20 to 40 inches. Tipper soils have a paralithic contact at 20 to 40 inches. Yenrab soils have more than 15 percent exchangeable sodium throughout.
GEOGRAPHIC SETTING: The Tipperary soils are on benches, dunes, hillslopes, plateaus, and terraces. Elevations are 4700 to 6,000 feet. Slope are 0 to 40 percent. The soils formed in alluvium or eolian materials. Average annual precipitation ranges from 4 to 10 inches. The mean annual temperature ranges from 45 to 51 degrees F. and mean summer temperature is 60 to 68 degrees F. The frost-free season is 90 to 140 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Appian, Apron, Griffy, Parran, and Trook soils. Appian soils have B2t horizons. Apron soils are coarse-loamy. Griffy soils are fine-loamy and have argillic horizons. Parran soils have salic horizons. Trook soils are coarse-loamy and have calcic horizons.
DRAINAGE AND PERMEABILITY: Somewhat excessively drained and excessively drained; slow and very slow runoff; rapid or very rapid permeability.
USE AND VEGETATION: These areas are used principally as native pastureland. In western Nevada some areas are irrigated. Alfalfa, pasture, orchards, and truck crops are grown under irrigation. Principal native vegetation is Indian ricegrass, cactus, prairie sandreed grass, needleandthread grass, rosedock, dalea, and littleleaf horsebrush.
DISTRIBUTION AND EXTENT: Basin areas of central and northern Wyoming, central and western Nevada, and northeast Utah. The series is of large extent.
