DAICK SERIES

The Daick series consists of very shallow and shallow, well drained soils that formed in residuum derived from tuffaceous sedimentary rocks. Daick soils are on hills and mountains. Slopes are 30 to 50 percent. The mean annual precipitation is about 180 mm and the mean annual temperature is about 9 degrees C.

TAXONOMIC CLASS: Clayey, smectitic, calcareous, mesic, shallow Typic Torriorthents

TYPICAL PEDON: Daick gravelly clay loam--rangeland. (Colors are for dry soil unless otherwise noted.)

A--0 to 3 cm; pale yellow (5Y 7/3) gravelly clay loam, olive (5Y 5/4) moist; weak very thin platy structure; slightly hard, very friable, moderately sticky and moderately plastic; many very fine roots; many very fine, many fine, and few medium vesicular pores; 10 percent gravel, 2 percent cobbles, and 3 percent stones; strongly effervescent; moderately alkaline (pH 8.4); abrupt smooth boundary. (3 to 8 cm thick)

C--3 to 10 cm; olive (5Y 5/4) clay, olive (5Y 5/4) moist; massive; hard, firm, very sticky and very plastic; many very fine and few fine roots; many very fine and few fine tubular pores; 2 percent gravel; strongly effervescent; moderately alkaline (pH 8.4); clear wavy boundary. (8 to 30 cm thick)

Cr--10 cm; pale olive (5Y 6/4) calcareous tuff, olive (5Y 5/4) moist.

TYPE LOCATION: Pershing County, Nevada; in Jersey Valley about 5 miles south-southeast of Needle Peak; about 2,500 feet south and 1,400 feet west of the northeast corner of section 4, T. 27 N., R. 40 E.; USGS Mount Moses 7.5 minute topographic quadrangle; latitude 40 degrees 14 minutes 30 seconds N and longitude 117 degrees 28 minutes 52 seconds W; WGS84 Decimal Degrees 40.2413889 latitude, -117.246944 longitude.

RANGE IN CHARACTERISTICS:
Soil moisture: Usually moist in winter and spring, dry late May through October; typic aridic soil moisture regime.
Mean annual soil temperature: 9 to 12 degrees C.
Depth to bedrock: 10 to 36 cm to a paralithic contact. The paralithic materials below the contact are tuffaceous sedimentary rocks.
Reaction Moderately alkaline or strongly alkaline.
Salinity (EC): 0 to 4 mmhos/cm.
Sodicity (SAR): 0 to 12.
Effervescence: Slightly effervescent or strongly effervescent.
Calcium carbonate equivalent: 1 to 5 percent.

Particle-size control section - Clay content: 35 to 60 percent.
Rock fragments: 5 to 25 percent, mainly gravel. Lithology of fragments is mainly volcanic rocks.

A horizon
Hue: 2.5Y or 5Y.
Value: 5 through 7 dry, 4 through 6 moist.
Chroma: 3 through 6 dry.
Consistence: Soft or slightly hard, dry.

C horizon
Hue: 2.5Y or 5Y.
Value: 4 or 5 moist.
Chroma: 1 through 4, dry or moist.
Texture: Clay or clay loam.
Consistence: Soft or slightly hard, dry; friable or very friable, moist.

COMPETING SERIES: These are the Bributte, Claysprings and Emco series.

Bributte soils have hue of 10R through 10YR, have sodium adsorption ratios of more than 13, and are moist in the moisture control section during May and June. Claysprings soils have hue of 2.5YR through 10YR and have paralithic materials that are soft clay shale. Emco soils have an SAR of greater than 15.

GEOGRAPHIC SETTING: Daick soils are on hills and mountains. These soils formed in residuum derived from tuffaceous sedimentary rocks. Slopes are 30 to 50 percent. Elevations range from 1,220 to 1,830 meters. The climate is arid with cool, moist winters and warm, dry summers. The mean annual precipitation is 130 to 200 mm, the mean annual temperature is 8 to 10 degrees C, and the frost-free period is 100 to 130 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bluewing, Oxcorel, and Tenabo soils. Bluewing and Oxcorel soils are very deep. Tenabo soils have a loamy control section.

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

USE AND VEGETATION: Daick soils are used for livestock grazing and wildlife habitat. The present vegetation is mainly shadscale, bud sagebrush, ephedra, bottlebrush squirreltail, and Indian ricegrass. Some areas of this soil have Bailey's greasewood.

DISTRIBUTION AND EXTENT: North-central Nevada. These soils are not extensive with about 7,500 acres of the series mapped to date. MLRAs 24 and 27.

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Davis, California.

SERIES ESTABLISHED: Pershing County (East Part), Nevada, 1986.

Ochric epipedon - The zone from the soil surface to 10 cm (A and C horizons).
Paralithic contact - The boundary at 10 cm to underlying soft bedrock (Cr layer).
Particle-size control section - The zone from the soil surface to 10 cm (A and C horizons).
