GROWSET SERIES

The Growset series consists of shallow, well drained soils that formed in residuum and colluvium derived from quartz monzonite. The Growset soils are on mountains. Slopes are 15 to 50 percent. The mean annual precipitation is about 460 mm and the mean annual temperature is about 6 degrees C.

TAXONOMIC CLASS: Loamy, mixed, superactive, frigid, shallow Typic Haploxerolls

TYPICAL PEDON: Growset gravelly sandy loam--rangeland. (Colors are for dry soil unless otherwise noted.) The soil surface is partially covered with approximately 25 percent gravel, 5 percent cobbles, and 1 percent stones.

A1--0 to 8 cm; brown (10YR 5/3) gravelly sandy loam, very dark grayish brown (10YR 3/2) moist; weak fine and medium subangular blocky structure parting to moderate medium granular; slightly hard, very friable, slightly sticky and nonplastic; many very fine and fine, few medium roots; many fine tubular and interstitial pores; 20 percent gravel, 5 percent cobbles and 1 percent stones; neutral (pH 6.8); clear wavy boundary. (5 to 10 cm thick)

A2--8 to 41 cm; brown (10YR 4/3) gravelly sandy loam, dark brown (10YR 3/3) moist; weak medium prismatic structure parting to weak fine and medium subangular blocky; slightly hard, very friable, slightly sticky and nonplastic; many very fine and fine, few medium roots; many fine tubular and interstitial pores; 20 percent gravel; neutral (pH 7.0); clear wavy boundary. (30 to 40 cm thick)

Cr--41 to 66 cm; weathered quartz monzonite.

TYPE LOCATION: White Pine County, Nevada; approximately 4000 feet up the repeater road from the Blue Mass scenic area road; about 1450 feet west and 2325 feet south of the southeast corner of Sec. 1, T. 21 N., R. 68 E.; latitude 39 degrees 43 minutes 27 seconds N and longitude 114 degrees 14 minutes 06 seconds W; NAD 83.

RANGE IN CHARACTERISTICS:
Soil moisture: Moist late fall through early summer, dry late July through October except for 10 to 20 days cumulative between July and October due to convection storms.
Mean annual soil temperature: 6 to 8 degrees C.
Mollic epipedon thickness: 36 to 50 cm.
Depth to paralithic contact: 36 to 50 cm.
Depth to unweathered bedrock: 64 to 100 cm.

Particle-size control section - Clay content: 10 to 18 percent.
Rock fragments: 15 to 35 percent, mostly gravel, with a high amount of 2 to 5 mm diameter gravel.

A horizons
Value: 4 or 5 dry, 2 or 3 moist.
Chroma: 2 or 3, dry or moist.
Clay content: 10 to 18 percent.

COMPETING SERIES: There are no competing series

GEOGRAPHIC SETTING: Growset soils are on mountain and typically occur on backslope positions. These soils formed in residuum and colluvium derived from quartz monzonite. Slopes are 15 to 50 percent. Elevations are 2,135 to 2,960 meters. The climate is cool, semiarid with warm, dry summers and cool, moist winters. The mean annual precipitation is 360 to 500 mm mean annual temperature is 4 to 6 degrees C, and the frost-free season is 50 to 70 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Kious, Pinwheel, and Ragamuffin series. Kious soils have a cryic soil temperature regime. Pinwheel soils have an argillic horizon and Ragamuffin soils are moderately deep to a paralithic contact.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained; medium to very high runoff; moderately high saturated hydraulic conductivity.

USE AND VEGETATION: Rangeland and wildlife habitat. The present vegetation is mainly mountain big sagebrush, mountain snowberry, and bluebunch wheatgrass.

DISTRIBUTION AND EXTENT: East Central Nevada. MLRA 28A. These soils are not extensive.

REMARKS: Diagnostic horizons and features recognized in this pedon are:
Mollic epipedon - The zone from the surface to 41 cm (A1 and A2 horizons).
Paralithic contact - The boundary at 41 cm (upper boundary of the Cr layer).
Particle size control section - The zone from 25 to 41 cm (part of the A2 horizon).
