WARDENOT SERIES
The Wardenot series consists of very deep, excessively drained soils that formed in alluvium derived from mixed rocks. Wardenot soils formed on alluvial fans, fan piedmonts, fan skirts, alluvial flats, and inset fans. Slopes are 0 to 30 percent. The mean annual precipitation is about 125 mm and the mean annual temperature is about 12 degrees C.
TAXONOMIC CLASS: Sandy-skeletal, mixed, mesic Typic Torriorthents
TYPICAL PEDON: Wardenot gravelly fine sandy loam--rangeland. (Colors are for dry soil unless otherwise noted.)
A1--0 to 8 cm; light brownish gray (10YR 6/2) gravelly fine sandy loam, very dark grayish brown (10YR 3/2) moist; massive; soft, very friable, nonsticky and nonplastic; few very fine, fine, medium and coarse roots; many very fine and few fine vesicular pores; 20 percent gravel; moderately alkaline (pH 8.4); abrupt smooth boundary. (3 to 15 cm thick)
A2--8 to 13 cm; pale brown (10YR 6/3) gravelly fine sandy loam, very dark grayish brown (10YR 3/2) moist; massive; soft, very friable, nonsticky and nonplastic; few very fine, fine and medium roots; many very fine interstitial and few very fine tubular pores; 30 percent gravel; moderately alkaline (pH 8.4); abrupt wavy boundary. (0 to 15 cm thick)
Bqk--13 to 64 cm; light brownish gray (10YR 6/2) very gravelly fine sandy loam, brown (10YR 4/3) moist; massive; soft, very friable, nonsticky and nonplastic; common very fine and few fine roots; many very fine tubular pores; 50 percent gravel; moderately thick white (10YR 8/1) carbonate coats on top and bottom of gravel, and very pale brown (10YR 7/3) silica coats on bottom of gravel; violently effervescent; strongly alkaline (pH 9.0); gradual wavy boundary. (8 to 60 cm thick)
Bk--64 to 152 cm; pale brown (10YR 6/3) very gravelly loamy sand, brown (10YR 4/3) moist; massive, soft, very friable, nonsticky and nonplastic; many very fine and common fine roots; many very fine interstitial pores; 55 percent gravel; white (10YR 8/1) lime coats on the undersides of gravel; strongly alkaline (pH 8.6)
TYPE LOCATION: Nye County, Nevada; about 2,600 north and 2,000 feet east of the southwest corner of section 36, T. 9 N., R. 42 E.; USGS Seyler Peak 7.5 minute topographic quadrangle; latitude 38 degrees 35 minutes 44 seconds N and longitude 117 degrees 12 minutes 53 seconds W; WGS84 Decimal Degrees 38.5955556 latitude, -117.2147222 longitude.
RANGE IN CHARACTERISTICS:
Soil moisture: Usually dry, moist in some part for short periods during winter and early spring months and for 10 to 20 days cumulative between July and October due to convection storms; typic aridic soil moisture regime.
Mean annual soil temperature: 12 to 15 degrees C.
Reaction: Slightly alkaline to strongly alkaline, commonly increases with depth.
Particle-size control section - Clay content: Averages 5 to 12 percent.
Rock fragments: Averages 40 to 75 percent; includes cobbles and stones.
A horizon
Value: 6 or 7 dry, 4 or 5 moist.
Chroma: 2 or 3.
Carbonates: Noneffervescent through strongly effervescent, may be violently effervescent where influenced by eolian depositions.
Bqk and Bk horizons
Value: 5 through 7 dry, 3 through 5 moist.
Chroma: 2 through 4.
Structure: Single grained or massive.
Consistence: Nonsticky to slightly sticky and nonplastic to slightly plastic.
Texture: Stratified extremely gravelly fine sandy loam to cobbly loamy sand. Strata of very gravelly or cobbly sandy loam or fine sandy loam in upper part of substratum.
Texture: Averages loamy sand.
Rock fragments: Average 40 to 75 percent; individual strata have as little as 25 percent rock fragments.
Other features: Carbonate and silica pendants commonly are present in some part of the B horizon.
Carbonates: Strongly effervescent or violently effervescent.
COMPETING SERIES: These are
Bluewing,

Nepalto and
Willwood series.
Bluewing,

Inmo,
Itme,
Izamatch,
Izo,
Ioka,
Leo and
Willwood soils lack Bqk horizons. Also, Bluewing, Inmo, Itme, Izo and Willwood soils lack strata of sandy loam in the control section.
Nepalto soils have hue of 2.5YR.
GEOGRAPHIC SETTING: Wardenot soils are on alluvial fans, fan piedmonts, fan skirts, alluvial flats and inset fans. These soils formed in alluvium derived from mixed rocks. Slopes are 0 to 30 percent. Elevations are 1,278 to 2,091 meters. The climate is semiarid and cool, moist winters and warm, dry summers. The mean annual temperature is 11 to 14 degrees C, the mean annual precipitation is 100 to 200 mm, and the frost-free season is about 100 to 150 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Unsel and the competing
Izo soils. Unsel soils have an argillic horizon.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Excessively drained; slow to medium runoff; high saturated hydraulic conductivity.
USE AND VEGETATION: Livestock grazing and wildlife habitat. The vegetation is mainly shadscale, bud sagebrush, Kings desertgrass, Indian ricegrass and galleta.
DISTRIBUTION AND EXTENT: Central Nevada. These soils are moderately extensive. MLRA 27, 29 and 28B.
