TEEBONE SERIES

The Teebone series consists of very deep, moderately well drained soils that formed in lacustrine deposits derived from mixed rocks. The Teebone soils are on lake plains and basin floors. Slopes are 0 to 4 percent. The mean annual precipitation is about 230 mm and the mean annual temperature is about 8 degrees C.

TAXONOMIC CLASS: Fine, smectitic, mesic Vertic Haplocalcids

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

A--0 to 5 cm; light brownish gray (10YR 6/2) silty clay loam, dark grayish brown (10YR 4/2) moist, moderate thick platy structure parting to strong very fine granular; hard, friable, very sticky and very plastic; common very fine and fine roots; many very fine vesicular pores; violently effervescent; strongly alkaline (pH 8.6); clear wavy boundary. (5 to 10 cm thick)

Bkn1--5 to 20 cm; grayish brown (10YR 5/2) silty clay loam, brown (10YR 5/3) moist; common fine distinct brown (7.5YR 5/4) redox concentrations along root channels; strong medium prismatic structure parting to strong fine angular blocky; very hard, firm, very sticky and very plastic; many very fine through medium roots; few very fine through medium tubular pores; common medium hard and firm nodules cemented by secondary calcium carbonate which slake in water; violently effervescent; very strongly alkaline (pH 9.6); clear wavy boundary. (13 to 25 cm thick)

Bkn2--20 to 43 cm; light brownish gray (10YR 6/2), silty clay loam, brown (10YR 5/3) moist; common fine distinct yellowish brown (10YR 5/4) Redox concentrations along root channels; moderate medium prismatic structure parting to strong fine angular blocky; hard, firm, very sticky and very plastic; common fine and medium roots; few very fine through medium tubular pores; common medium hard and firm nodules cemented by secondary calcium carbonate which slake in water; violently effervescent; very strongly alkaline (pH 9.6); clear wavy boundary. (20 to 25 cm thick)

Bkn3--43 to 79 cm; light brownish gray (10YR 6/2), silty clay loam, brown (10YR 5/3) moist; common medium faint yellowish brown (10YR 5/4) redox concentrations along root channels; moderate coarse prismatic structure parting to moderate medium subangular blocky; hard, firm, very sticky and very plastic; few fine and medium roots; few fine tubular pores; common medium hard and firm nodules cemented by secondary calcium carbonate which slake in water; violently effervescent; very strongly alkaline (pH 9.6); gradual wavy boundary. (30 to 40 cm thick)

Bkng1--79 to 127 cm; light gray (5Y 7/2) silty clay, light olive gray (5Y 6/2) moist; few fine distinct black (10YR 2/1) manganese stains; massive; slightly hard, friable, very sticky and very plastic; few fine and medium roots; few fine tubular pores; many fine powdery masses of secondary calcium carbonate; violently effervescent; very strongly alkaline (pH 9.6); gradual wavy boundary.

TYPE LOCATION: Lincoln County, Nevada; approximately 4 miles west of Gouge Eye Well, 1240 feet north and 860 feet west of the southeast corner of section 31, T. 9 N., R. 65 E.; USGS Gouge Eye Well 7.5 minute topographic quadrangle; latitude 38 degrees 35 minutes 34 seconds N and longitude 114 degrees 37 minutes 25 seconds W; NAD 83.

RANGE IN CHARACTERISTICS:
Soil Moisture: Usually dry, moist in winter and early spring and intermittently moist for 10 to 20 days cumulative between July and September due to convection storms. The water table is within 90 to 150 cm of the soil surface in early spring.
Mean annual soil temperature: 9 to 11 degrees C.
Salinity (EC): 4 to 8 millimhos/cm.

Particle-size control Section - Clay content: 35 to 50 percent.

A horizon
Hue: 10YR or 2.5Y.
Value: 6 through 8 dry, 4 through 6 moist.
Chroma: 2 or 3, dry or moist.
Reaction: Strongly alkaline or very strongly alkaline.
Calcium Carbonate Equivalent: 15 to 25 percent.
Sodicity (SAR): 1 to 5.

Bkn horizons - Hue: 10YR or 2.5Y.
Value: 5 through 7 dry, 5 or 6 moist.
Chroma: 2 through 4, dry or moist.
Texture: Silty clay, or silty clay loam.
Calcium Carbonate Equivalent: 25 to 40 percent and is 5 percent or more higher than in the Bkng horizons.
Sodicity (SAR): 13 to 45.
Redox concentrations: High chromas are absent in some pedons.

Bkng horizons
Hue: 2.5Y, or 5Y.
Value: 6 or 7 dry, 5 or 6 moist.
Chroma: 1 or 2, dry or moist.
Texture: Clay, silty clay, or silty clay loam.
Calcium Carbonate Equivalent: 20 to 30 percent.
Sodicity (SAR): 13 to 45.
Redox concentrations: Few to common, black or reddish redoximorphic concentrations.

COMPETING SERIES: There are no competing series.

GEOGRAPHIC SETTING: Teebone soils are on lake plains and basin floors. These soils formed in lacustrine deposits derived from mixed rocks. Slopes are 0 to 4 percent. Elevations are 1,680 to 1,895 meters. The climate is semiarid with warm, dry summers and cool moist winters. The mean annual precipitation is 200 to 250 mm, mean annual temperature is 8 to 10 degrees C, and the frost free season is 100 to 120 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Chuffa, and Yobe series. Chuffa and Yobe soils lack calcic horizons and have a fine-silty particle size control section.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Moderately well drained, very low to high runoff; moderately low saturated hydraulic conductivity . A water table at depths of 90 to 150 cm is commonly present in late winter and early spring.

USE AND VEGETATION: Livestock grazing and wildlife habitat. The potential native vegetation is mainly black greasewood and shadscale. This pedon is correlated to Ecological Site R028AY008NV, Sodic Terrace 8-10 P.Z.

DISTRIBUTION AND EXTENT: Southeastern Nevada. These soils are not extensive. MLRA 28A.
