BEDELL SERIES

The Bedell series consists of very deep, somewhat excessively drained soils that formed in alluvium derived mainly from granitic rocks. Bedell soils are on fan remnants and stream terraces. Slopes are 0 to 15 percent. The mean annual precipitation is about 250 mm and the mean annual temperature is about 9 degrees C.

TAXONOMIC CLASS: Coarse-loamy, mixed, superactive, mesic Aridic Argixerolls

TYPICAL PEDON: Bedell loamy sand--rangeland. (Colors are for dry soil unless otherwise noted.)

A1--0 to 3 cm; grayish brown (10YR 5/2) loamy sand, very dark grayish brown (10YR 3/2) moist; weak fine and medium subangular blocky structure; soft, very friable, nonsticky and nonplastic; many very fine and fine roots; many very fine and fine interstitial pores; 10 percent fine gravel; neutral (pH 6.6); clear smooth boundary. (0 to 10 cm thick)

A2--3 to 38 cm; grayish brown (10YR 5/2) loamy sand, very dark grayish brown (10YR 3/2) moist; weak medium and coarse subangular blocky structure; soft, very friable, slightly sticky and nonplastic; many very fine, fine and medium roots; many very fine and fine tubular pores; 10 percent fine gravel; neutral (pH 6.8); clear smooth boundary. (5 to 40 cm thick)

Bt1--38 to 61 cm; yellowish brown (10YR 5/4) sandy loam, dark yellowish brown (10YR 3/4) moist; massive; very hard, friable, slightly sticky and slightly plastic; few very fine, fine and medium roots; few very fin and fine tubular pores; common faint clay films on rock fragments, sand grains and lining pores; 10 percent fine gravel; neutral (pH 6.8); gradual smooth boundary. (13 to 30 cm thick)

Bt2--61 to 137 cm; yellowish brown (10YR 5/4) sandy loam, dark yellowish brown (10YR 3/4) moist; massive; hard, friable, slightly sticky and slightly plastic; few very fine, fine and medium roots; few very fine and fine tubular pores; common faint clay films on rock fragments and sand grains; 10 percent fine gravel; neutral (pH 6.8); gradual smooth boundary. (25 to 76 cm thick)

C--137 to 165 cm; pale brown (10YR 6/3) loamy coarse sand, brown (10YR 4/3) moist; massive; slightly hard, very friable, nonsticky and nonplastic; few very fine, fine and medium roots; many very fine and fine interstitial pores; 10 percent fine gravel; neutral (pH 6.8).

TYPE LOCATION: Washoe County, Nevada; about 18 miles northwest of Reno; approximately 2,050 feet north and 100 feet east of the southwest corner of section 6, T. 22 N., R. 19 E.; USGS Granite Peak 7.5 minute topographic quadrangle; latitude 39 degrees 47 minutes 55 seconds N and longitude 119 degrees 54 minutes 12 seconds W; WGS84 Decimal Degrees 39.8005556 latitude, -119.9033333 longitude.

RANGE IN CHARACTERISTICS:
Soil moisture: Usually moist in the late winter and early spring; dry during the summer and autumn months; aridic soil moisture regime that borders on xeric.
Mean annual soil temperature: 9 to 12 degrees C.
Depth to base of argillic horizon: 75 to 140 cm.
Reaction: Slightly acid or neutral.

Particle-size control section - Clay content: 8 to 18 percent.
Rock fragments: 5 to 20 percent gravel. Lithology of fragments is mostly granitic rock.

A horizons
Value: 4 or 5 dry, 2 or 3 moist.
Chroma: 2 or 3.
Organic matter content: More than 1 percent to a depth of 25 cm or more.

Bt horizons
Hue: 10YR or 7.5YR.
Value: 4 through 6 dry, 4 or 5 moist.
Chroma: 3 or 4, dry or moist.

C horizon
Value: 5 or 6 dry, 4 or 5 moist.
Chroma: 3 or 4, dry or moist.
Texture: Gravelly loamy sand to sandy loam and is stony in some pedons.

COMPETING SERIES: This is the Sacatar series. Sacatar soils are moderately deep to paralithic contacts.

GEOGRAPHIC SETTING: Bedell soils are on fan remnants and stream terraces. These soils formed in alluvium derived mainly from granitic rocks. Slopes are 0 to 15 percent. Elevations range from 1,375 to 1,830 meters. The climate is semiarid with cool, moist winters and warm, dry summers. The mean annual precipitation is 200 to 300 mm, the mean annual temperature is 8 to 10 degrees C., and the frost-free period is about 100 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Lemm, Mottsville, and Orr soils. Lemm soils are loamy-skeletal. Orr soils are fine-loamy. Mottsville soils are sandy and do not have argillic horizons.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Somewhat excessively drained; moderately rapid permeability; high saturated hydraulic conductivity.

USE AND VEGETATION: Bedell soils are used for recreation, wildlife habitat, and urban development. The native vegetation is mainly Wyoming big sagebrush, antelope bitterbrush, Douglas rabbitbrush, bottlebrush squirreltail, and Anderson's peachbrush.

DISTRIBUTION AND EXTENT: Western Nevada. These soils are not extensive with about 5,500 acres of the series mapped to date. MLRA 26.
