NOSLO SERIES
The Noslo series consists of moderately deep, well drained soils that formed in residuum and colluvium derived from granitic rock with additions of eolian material. Noslo soils are on mountains. Slopes are 30 to 50 percent. The mean annual precipitation is about 280 mm and the mean annual temperature is about 8 degrees C.
TAXONOMIC CLASS: Fine-loamy, mixed, superactive, mesic Aridic Argixerolls
TYPICAL PEDON: Noslo bouldery sandy loam--rangeland. (Colors are for dry soil unless otherwise noted.) The soil surface is covered with 30 percent boulders, 5 percent stones, 5 percent cobbles, and 10 percent gravel.
A1--0 to 20 cm; brown (10YR 5/3) bouldery sandy loam, dark brown (10YR 3/3) moist; weak medium subangular blocky parting to weak fine granular structure; soft, very friable, slightly sticky and slightly plastic; many very fine roots; common very fine interstitial and tubular pores; 10 percent boulders, 2 percent cobbles, and 20 percent gravel; neutral (pH 7.3); clear smooth boundary. (8 to 20 cm thick)
A2--20 to 33 cm; brown (10YR 5/3) bouldery sandy loam, dark brown (10YR 3/3) moist; moderate medium granular structure; hard, very friable, slightly sticky and slightly plastic; many very fine and common fine and medium roots; common very fine and fine tubular pores; 10 percent boulders and 10 percent gravel; neutral (pH 7.3); clear smooth boundary. (10 to 20 cm thick)
Bt--33 to 76 cm; yellowish brown (10YR 5/4) sandy clay loam, brown (10YR 4/3) moist; strong medium subangular blocky structure; hard, firm, moderately sticky and moderately plastic; common very fine, fine and medium roots; common very fine tubular pores; common distinct clay films lining pores and clay bridges between mineral grains; 10 percent gravel; neutral (pH 7.3); abrupt wavy boundary. (30 to 50 cm thick)
Cr--76 cm; weathered granitic rock.
TYPE LOCATION: Washoe County, Nevada; in the Granite Range about 7 miles north-northeast of Gerlach; approximately 1,800 feet north and 2,000 feet west of the southeast corner of section 11, T. 33 N., R. 23 E.; USGS Hualapai Flat South 7.5 minute topographic quadrangle; latitude 40 degrees 45 minutes 17 seconds N and longitude 119 degrees 20 minutes 18 seconds W; WGS84 Decimal Degrees 40.7547222 latitude, -119.3383333 longitude.
RANGE IN CHARACTERISTICS:
Soil moisture: Usually moist in winter, spring, and early summer, dry from mid-July through mid-October; aridic soil moisture regime that borders on xeric.
Mean annual soil temperature: 8 to 11 degrees C.
Mollic epipedon thickness: 20 to 36 cm; does not include the Bt horizon.
Depth to bedrock: 50 to 100 cm to a paralithic contact. The paralithic materials below the contact are weathered granitic rock.
Particle-size control section - Clay content: 25 to 35 percent.
Sand content: 50 to 70 percent;
Rock fragments: 0 to 15 percent, dominated by fine (2 to 5 mm diameter) gravel. Lithology of fragments is granitic rock such as granite or granodiorite.
A horizons
Chroma: 2 or 3, dry or moist.
Reaction: Slightly acid or neutral.
Organic matter content: 1 to 3 percent.
Bt horizon
Value: 5 or 6 dry.
Chroma: 3 or 4, dry or moist.

Truax, and
Wenatchee soils are greater than 100 cm to bedrock.
Bjork soils are not dominated by 2 to 5 mm diameter gravel, have slightly alkaline argillic horizons, and have moderate or strong prismatic structure.
Dodes soils have 10 to 30 percent pararock fragments of diatomite and do not have weathered granitic rock in the series control section.
Indiano and
Pahrange soils have 15 to 35 percent gravel in the argillic horizon and are moderately deep to lithic contacts.
Madras and
Quiero soils are moderately deep to lithic contacts.
Shoebend soils have mean annual soil temperature of 11 to 12 degrees C. and have frost-free periods of 140 to 155 days.
Simcoe soils have less than 50 percent sand in the particle-size control section and have clay loam, silt loam, or silty clay loam texture in the argillic horizon.
Uhaldi soils have 15 to 35 percent rock fragments and less than 50 percent sand in the particle-size control section.
GEOGRAPHIC SETTING: Noslo soils are on mountains. They typically occur on backslope positions. These soils formed in residuum and colluvium derived from granitic rocks with additions of eolian materials. Slopes are 30 to 50 percent. Elevations range from 1,345 to 1,925 meters. The climate is semiarid with cool, moist winters and warm, dry summers. The mean annual precipitation is 250 to 300 mm, the mean annual temperature is 7 to 9 degrees C, and the frost-free period is 70 to 90 days.
GEOGRAPHICALLY ASSOCIATED SOILS: This is the
Berit soil. Berit soils are shallow to paralithic contacts and have ochric epipedons.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained; medium surface runoff; moderately high saturated hydraulic conductivity.
USE AND VEGETATION: Noslo soils are used for rangeland and wildlife habitat. The present vegetation is mainly bluebunch wheatgrass, Lahontan sagebrush, Sandberg's bluegrass, and Thurber's needlegrass with scattered Utah juniper.
DISTRIBUTION AND EXTENT: Northwestern Nevada. These soils are not extensive with about 1,900 acres of the series mapped to date. MLRA 23.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Davis, California.
SERIES ESTABLISHED: Washoe County, Nevada, Central Part, 1990. The name is coined.
