<br />BOWDISH SERIES
<br />The Bowdish series consists of moderately deep, well drained soils that are formed in residuum
<br />derived dominantly from sandstone and interbedded shale. Bowdish soils are on mesas, benches,
<br />ridges, and escarpments and have slopes of 1 to 30 percent. The mean annual precipitation is
<br />about 13 inches and the mean annual temperature is about 47 degrees F.
<br />TAXONOMIC CLASS: Fine - loamy, mixed, superactive, mesic Ustic Haplocalcids
<br />TYPICAL PEDON: Bowdish loam - pinon- Juniper woodland. (Colors are for air dry soil unless
<br />otherwise noted.)
<br />A - -O to 5 inches; brown (7.5YR 5/4) loam, dark brown (7.5YR 4/4) moist; weak medium subangular
<br />blocky structure; slightly hard, very friable, nonsticky and slightly plastic; strongly effervescent;
<br />moderately alkaline (pH 8.0); clear smooth boundary. (4 to 8 inches thick)
<br />Bw - -5 to 12 inches; light brown (7.5YR 6/4) loam, brown (7.5YR 5/4) moist; moderate medium
<br />subangular blocky structure; hard, friable, nonsticky and nonplastic; lime disseminated throughout;
<br />violently effervescent; moderately alkaline (pH 8.0); clear smooth boundary. (6 to 12 inches thick)
<br />Bk -12 to 23 inches; pinkish white (7.5YR 8/2) gravelly loam, light brown (7.5YR 6/4) moist; weak
<br />medium subangular blocky structure; hard, friable, nonsticky and slightly plastic; 15 percent pebbles;
<br />lime disseminated throughout; violently effervescent; moderately alkaline (pH 8.2); abrupt wavy
<br />boundary. (10 to 20 inches thick)
<br />R -23 inches; hard sandstone.
<br />TYPE LOCATION: Montrose County, Colorado, about 2.5 miles west and 3.5 miles north of Uravan,
<br />150 feet east and 700 feet south of the northwest corner, sec. 18, T. 48 N., R. 17 W.
<br />RANGE IN CHARACTERISTICS: Depth to the calcic horizon ranges from 5 to 20 inches. Depth to
<br />the lithic contact ranges from 20 to 40 inches.
<br />The A and Bw horizons have hue of 7.5YR or 5YR, 4 to 6, 4 or 5 moist and chroma of 2 to 4. The
<br />rock fragment content ranges from 0 to 30 percent, and is predominantly pebble and cobble sized.
<br />Reaction is mildly alkaline or moderately alkaline. The Bk horizon has hue of 10YR through 2.5YR
<br />hue, 5 to 8, 3 to 6 moist, and chroma of 3 to 6. The texture is loam, sandy clay loam, clay loam, or
<br />thin layers of sandy loam. The clay content is 18 to 35 percent. The rock fragment content is 0 to 30
<br />percent, and is predominantly pebble size. Reaction is moderately alkaline or strongly alkaline. The
<br />calcium carbonate equivalent ranges from 15 to 40 percent. COMPETING SERIES: These are the
<br />Abra, Bighams, Cibeque, Copeman, Creel, Darvey, Harvey, Hernandez, Honlu, Numa, and Pultney
<br />series. Abra, Cibeque, Darvey, Harvey, Hernandez, Honlu, and Numa soils are deep. Pultney soils
<br />have 10YR and yellower hues and have 10 to 15 percent exchangeable sodium in the Cky horizon.
<br />Bighams soils have a paralithic contact at 20 to 40 inches. Creel soils have soil temperatures of 54
<br />to 59 degrees F. Copeman soils have horizons of secondary gypsum accumulation.
<br />GEOGRAPHIC SETTING: Bowdish soils are on mesas, benches, and escarpments. Slopes range
<br />from 1 to 30 percent. The soil formed in residuum derived dominantly from interbedded sandstone
<br />and shale. Elevation ranges from 5,000 to 7,300 feet. The mean annual precipitation ranges from 9
<br />to 15 inches. Mean annual temperature ranges from 46 to 50 degrees F. The frost -free season is
<br />about 110 to 150 days.
<br />GEOGRAPHICALLY ASSOCIATED SOILS: These are the Pinon, Clovis, and Progresso soils.
<br />Pinon soils have bedrock at less than 20 inches. Clovis soils are deep and have an argillic horizon.
