LOCATION JAYBEE NV+CAEstablished Series
TAXONOMIC CLASS: Loamy, mixed, superactive, mesic Lithic Xeric Haplargids
TYPICAL PEDON: Jaybee very cobbly sandy loam--rangeland. (Colors are for dry soil unless otherwise noted.) The soil surface is covered with 25 percent gravel and 25 percent cobbles.
A1--0 to 4 inches; pale brown (10YR 6/3) very cobbly sandy loam, dark grayish brown (10YR 4/2) moist; moderate fine and medium subangular blocky structure; slightly hard, very friable, slightly sticky and nonplastic; few very fine roots; few very fine tubular and common very fine vesicular pores; 15 percent gravel and 20 percent cobbles; slightly alkaline (pH 7.4); clear smooth boundary. (2 to 5 inches thick)
A2--4 to 8 inches; brown (10YR 5/3) gravelly sandy clay loam, dark brown (10YR 3/3) moist; moderate fine subangular blocky structure; slightly hard, very friable, slightly sticky and slightly plastic; few very fine roots; few very fine tubular and common very fine interstitial pores; 25 percent gravel; neutral (pH 7.2); clear smooth boundary. (0 to 5 inches thick)
Bt--8 to 14 inches; brown (10YR 5/3) gravelly clay, dark yellowish brown (10YR 4/4) moist; weak medium prismatic structure parting to fine subangular blocky; hard; very friable, moderately sticky and moderately plastic; few very fine, common medium, and common coarse roots; common very fine tubular pores; common distinct clay films on faces of peds and lining pores; 20 percent gravel and 5 percent cobbles; neutral (pH 6.8); abrupt irregular boundary. (3 to 10 inches thick)
R--14 inches; fractured, unweathered basalt.
TYPE LOCATION: Washoe County, Nevada; west of the Smoke Creek Desert and about 2 miles northeast of Burro Mountain; approximately 1,400 feet south and 260 feet east of the northwest corner of section 16, T. 31 N., R. 19 E.; USGS Salt Marsh 7.5 minute topographic quadrangle; 40 degrees 33 minutes 54.7 seconds north latitude and 119 degrees 51 minutes 38.6 seconds west longitude, NAD83.
RANGE IN CHARACTERISTICS:
Soil moisture - Usually moist during winter and spring, dry during summer and fall; Aridic moisture regime that borders on xeric.
Mean annual soil temperature - 54 to 57 degrees F.
Depth to bedrock - 7 to 14 inches to a lithic contact.
Particle-size control section - Clay content: Averages 25 to 35 percent;
Rock fragments: Averages 15 to 35 percent, mainly pebbles. Lithology of fragments are volcanic rocks such as basalt.
A horizons
Hue: 10YR or 7.5YR.
Value: 4 through 6 dry, 3 or 4 moist; The upper 7 inches after mixing has value of 6 dry or 4 moist.
Chroma: 2 through 4, dry or moist.
Clay content: 15 to 25 percent.
Reaction: Neutral or slightly alkaline.
Bt horizon
Hue: 10YR or 7.5YR.
Value: 5 or 6 dry, 3 or 4 moist.
Chroma: 2 through 4, dry or moist.
Texture: Gravelly clay or gravelly clay loam.
Clay content: 35 to 45 percent.
Rock fragments: 15 to 35 percent.
Reaction: Neutral or slightly alkaline.
COMPETING SERIES: These are the Banbury, Bombadil, Dougal, Fubble, Kreza, Meninik (T), and Stumount (T) series. These soils all have less than 35 percent clay in the argillic horizon.
GEOGRAPHIC SETTING: Jaybee soils are on hills, mountains, and plateaus. These soils formed in residuum and colluvium derived from basalt or similar volcanic rocks. Slopes are 2 to 50 percent. Elevations range from 4,300 to 6,400 feet. The climate is semiarid with cool, moist winters and warm, dry summers. The mean annual precipitation is 8 to 12 inches, the mean annual temperature is 48 to 54 degrees F., and the frost-free period is 80 to 100 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Pickup and Wylo soils. Pickup soils are clayey-skeletal, moderately deep to lithic contacts, and have mollic epipedons. Wylo soils are clayey and have mollic epipedons.
DRAINAGE AND PERMEABILITY: Well drained; high or very high surface runoff; slow permeability (moderately low or moderately high saturated hydraulic conductivity).
USE AND VEGETATION: Jaybee soils are used for rangeland and wildlife habitat. The present vegetation is mainly Lahontan sagebrush, bottlebrush squirreltail, cheatgrass, and Thurber's needlegrass.
DISTRIBUTION AND EXTENT: Northwestern Nevada and northeastern California. These soils are moderately extensive. MLRA 23.
MLRA OFFICE RESPONSIBLE: Reno, Nevada.
SERIES ESTABLISHED: Washoe County, Nevada (Central Part), 1990.
REMARKS: Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon - The zone from the soil surface to 8 inches (A1 and A2 horizons).
Argillic horizon - The zone from 8 to 14 inches (Bt horizon).
Lithic contact - The boundary at 14 inches to underlying hard bedrock (R layer).
Particle-size control section - The zone from the soil surface to 14 inches (A1, A2, and Bt horizons).
ADDITIONAL DATA: A very similar soil to Jaybee from near the series type location is sampled for full characterization by the Soil Survey Laboratory (SSL), Lincoln, NE, as soil survey sample number S86NV-031-001 (pedon # 86P0903).
