BUDIHOL SERIES

The Budihol series consists of very shallow and shallow, well drained soils formed in residuum and colluvium derived from granitic rocks. These soils are on mountains, hills and sideslopes. Slopes are 15 to 75 percent. Mean annual precipitation is about 230 mm and mean annual temperature is about 9 degrees C.

TAXONOMIC CLASS: Loamy, mixed, superactive, nonacid, mesic, shallow Xeric Torriorthents

TYPICAL PEDON: Budihol gravelly sandy loam--rangeland. (Colors are for dry soil unless otherwise noted.) The soil surface is covered with 5 percent cobbles and 25 percent fine gravel.

A1--0 to 8 cm; light brownish gray (10YR 6/2) gravelly sandy loam, dark grayish brown (10YR 4/2) moist; weak fine subangular blocky structure; soft, very friable, slightly sticky and nonplastic; many very fine roots; many very fine tubular pores; 25 percent fine gravel; neutral (pH 6.8); clear smooth boundary. (5 to 15 cm thick)

A2--8 to 18 cm; pale brown (10YR 6/3) gravelly sandy loam, brown (10YR 4/3) moist; weak fine and medium subangular blocky structure; soft, very friable, slightly sticky and nonplastic; common very fine roots; common very fine and fine tubular pores; 30 percent fine gravel; neutral (pH 7.0); clear smooth boundary. (3 to 30 cm thick)

Cr--18 to 53 cm; weathered granodiorite; very gravelly sandy loam in some fractures about 1.3 to 2.5 cm thick. (23 to 43 cm thick)

R--53 cm; hard granodiorite.

TYPE LOCATION: Churchill County, Nevada. Approximately 2,200 feet west and 1,300 feet north of the southeast corner of Section 17, T. 15 N., R. 32 E.; latitude 39 degrees 9 minutes 52.9 seconds N and longitude 118 degrees 23 minutes 50.2 seconds W;WGS84 Decimal Degrees 39.1646944 latitude, 118.3972778 longitude.

RANGE IN CHARACTERISTICS:
Soil moisture: Usually dry, moist in winter and spring, dry in summer and fall, aridic soil moisture regime bordering on xeric.
Mean annual soil temperature: 8 to 12 degrees C.
Depth to weathered bedrock: 15 to 36 cm.
Depth to unweathered bedrock: 50 to 76 cm.

Particle-size control section - Clay content: 12 to 18 percent.
Rock fragments: 15 to 35 percent. (Mostly fine gravel)

A1 horizon
Value: 5 or 6 dry, 3 or 4 moist.
Chroma: 2 or 3.

A2 horizon
Value: 5 or 6 dry, 3 or 4 moist.
Chroma: 2 or 3.
Texture: Gravelly sandy loam or gravelly coarse sandy loam.

COMPETING SERIES: These are the Boondock, Haar, and Nicanor series.

Boondock, and Haar soils lack hard bedrock within 100 cm. Boondock soils have 18 to 30 percent clay. Nicanor and Porterfield soils have 18 to 27 percent clay and less than 50 percent sand in the control section. Haar soils have 50 to 70 percent soft gravel.

GEOGRAPHIC SETTING: Budihol soils are on mountain peaks, hills and sideslopes. These soils formed in residuum and colluvium derived from granitic rocks. Slopes are 15 to 75 percent. Elevations are 1,310 to 2,135 meters. The climate is semi-arid with cool, moist winters and hot dry summers. The mean annual precipitation is 200 to 250 mm, mean annual temperature is 8 to 10 degrees C, mean summer temperature is about 19 degrees C, and the frost-free season is 90 to 100 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bimmer and Uripnes soils. Bimmer soils are dry in all parts of the moisture control section three-fourths or more of the time the soil temperature is 5 degrees C or higher at the top of the bedrock. Uripnes soils have more than 35 percent rock fragments in their control section.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained, rapid runoff; high saturated hydraulic conductivity.

USE AND VEGETATION: Rangeland and wildlife habitat. The present vegetation is mainly Wyoming big sagebrush and pine bluegrass, with some spiny hopsage, Nevada ephedra and horsebrush.

DISTRIBUTION AND EXTENT: Mountains in Central Nevada. Budihol soils are of small extent. MLRA 27, 29.
