TULERT SERIES

The Tulert series consists of moderately deep, well drained soils that formed in alluvium weathered from limestone and volcanic rocks. Tulert soils are on alluvial fans and have slopes of 0 to 4 percent. The mean annual precipitation is about 7 inches and the mean annual air temperature is about 64 1/4 F.

TAXONOMIC CLASS: Coarse-loamy, mixed, superactive, thermic Argidic Argidurids

TYPICAL PEDON: Tulert gravelly sandy loam, rangeland. (Colors are for dry soil unless otherwise noted.) All--0 to l inch; yellowish brown (l0YR 5/4) very gravelly sandy loam, dark yellowish brown (l0YR 4/4) moist; weak thin and medium platy structure; soft, very friable, nonsticky, nonplastic; few fine vesicular pores; 40 percent gravel; slightly effervescent; strongly alkaline (pH 8.6); abrupt smooth boundary. (l to 2 inches thick)

Al2--l to 3 inches, reddish yellow (7.5YR 6/6) gravelly sandy loam, brown (7.5YR 4/4) moist; weak medium platy structure; soft, friable, non sticky, nonplastic; few to common fine roots; few fine tubular pores; 25 percent gravel; slightly effervescent; strongly alkaline (pH 8.8); abrupt smooth boundary. (2 to 3 inches thick)

Bll--3 to 8 inches; reddish yellow (7.5YR 6/6) sandy loam, brown (7.5 4/4) moist; moderate medium subangular blocky structure; slightly hard, friable, nonsticky, slightly plastic; common fine roots; common fine tubular pores; l0 percent gravel; slightly effervescent; strongly alkaline (pH 8.8); clear smooth boundary. (4 to 7 inches thick)

Bl2--8 to l5 inches; brown (7.5YR 5/4) loam, dark brown (7.5YR 4/4) moist; moderate medium subangular blocky structure; slightly hard, friable, slightly sticky, slightly plastic; common fine roots; few fine tubular pores; common thin clay films bridging mineral grains; slightly effervescent; strongly alkaline (pH 8.8); abrupt wavy boundary. (6 to 8 inches thick)

IIB2ltcab--l5 to 20 inches; strong brown (7.5YR 5/6) loam, dark brown (7.5YR 4/4) moist; moderate medium angular blocky structure; hard, friable, sticky, slightly plastic; common fine roots; few to common fine tubular pores; common thin clay films on faces of peds and few thin clay films bridging mineral grains; common fine soft masses of lime; slightly effervescent; strongly alkaline (pH 8.8); clear smooth boundary. (4 to 6 inches thick)

IIB22tcab--20 to 60 inches; strong brown (7.5YR 5/6) sandy clay loam, dark brown (7.5YR 4/4) mosit; moderate medium angular blocky structure; very hard, firm, slightly sticky, slightly plastic; few fine roots; few fine tubular pores; common thin clay films on faces of peds and many thin clay films bridging mineral grains; slightly effervescent matrix with violently effervescent spots; strongly alkaline (pH 8.8); abrupt wavy boundary. (5 to 6 inches thick)

IIB23tcab--26 to 3l inches; brown (7.5YR 5/4) sandy loam, dark brown (7.5YR 4/4) moist; moderate thick platy structure; hard, very friable, non sticky, nonplastic; few fine roots; common very fine interstitial and few fine tubular pores; few thin clay films on faces of peds and many thin clay films bridging mineral grains; noneffervescent matrix with strongly effer vescent spots; strongly alkaline (pH 8.8); abrupt wavy boundary. (3 to 6 inches thick)

IIB3cab--3l to 38 inches; pinkish gray (7.5YR 7/2) fine sandy loam, brown (7.5YR 5/4) moist; moderate fine subangular blocky structure; slightly hard, slightly brittle; nonsticky, nonplastic; pores mostly filled with disseminated lime; few cylindrical concretions; violently effervescent; strongly alkaline (pH 8.9); abrupt wavy boundary. (5 to 8 inches thick)

IIClsicamb--38 to 42 inches; white (l0YR 8/2) strongly cemented duripan, light gray (l0YR 7/2) moist, with a thin (0.5 to l.0 mm) indurated cap; massive; extremely hard, extremely firm; abrupt wavy boundary. (4 to 8 inches thick)

IIIC2b--42 to 55 inches; light brownish gray (l0YR 6/2) and very pale brown (l0YR 7/2) very gravelly loamy sand, dark grayish brown (l0YR 4/2) and brown (l0YR 5/3) moist; massive; soft, very friable, nonsticky, nonplastic; many fine and medium interstitial pores; 45 percent gravel; strongly and violently effervescent; strongly alkaline (pH 8.9).

TYPE LOCATION: Lincoln County, Nevada; Tule Desert, about l,300 feet south of the west l/4 corner of sec. l7, T.9S., R.69E.

RANGE IN CHARACTERISTICS: The thickness of the solum and depth to the duripan are 30 to 40 inches. The soil is usually dry from May to December. Mean annual soil temperature is about 63 1/4 to 66 1/4 F.

The A horizon has hue of l0YR or 7.5YR. The average gravel content ranges from 25 to 35 percent by volume.

The B2t horizon has chroma of 4 or 6 dry. The average texture is loam or sandy loam with less than l8 percent clay and less than l5 percent rock fragments. Subhorizons of loam, sandy clay loam or sandy loam with more than l8 percent clay are in most pedons.

COMPETING SERIES: These are the Cleaver, Delamar, Silent and Spanel series. Cleaver, Silent and Spanel soils have duripans within 20 inches of the sur face and mesic soil temperatures. Delamar soils have fine-loamy argillic horizons and mesic soil temperatures.

GEOGRAPHIC SETTING: Tulert soils are on long slightly concave alluvial fans and have slopes of 0 to 4 percent. They formed from moderately coarse tex tured alluvium weathered from mostly limestone and mixed volcanic rocks. Elevations are 3,000 to 4,000 feet. The climate is hot and arid with a mean annual precipitation of 6 to 8 inches; mean annual temperature of 59 1/4 to 62 1/4 F.; and a frost-free season of about 200 to 2l0 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Mormon Mesa soils which lack argillic horizons and have petrocalcic horizons within 20 inches of the surface.

DRAINAGE AND PERMEABILITY: Well drained; slow runoff; moderately slow permeability.

USE AND VEGETATION: Rangeland. The vegetation is principally creosote bush, spiny hopsage, filaree and cacti.

DISTRIBUTION AND EXTENT: Southeastern Nevada. Tulert soils are of small extent.
