KYLER SERIES

The Kyler series consists of very shallow and shallow, well drained soils that formed in residuum and colluvium derived from limestone and dolomite. Kyler soils are on mountains and hills. Slopes are 4 to 75 percent. The mean annual precipitation is about 300 mm and the mean annual temperature is about 12 degrees C.

TAXONOMIC CLASS: Loamy-skeletal, carbonatic, mesic Lithic Xeric Torriorthents

TYPICAL PEDON: Kyler extremely cobbly loam--rangeland. (Colors are for dry soil unless otherwise noted.) The soil surface is partially covered with 30 percent cobbles and 35 percent gravel.

A--0 to 8 cm; pale brown (10YR 6/3) extremely cobbly loam, brown (10YR 4/3) moist; moderate thin platy structure; soft, very friable, slightly sticky and slightly plastic; many very fine roots; many very fine and fine interstitial pores; 30 percent cobbles and 35 percent gravel; violently effervescent; moderately alkaline (pH 7.9); clear smooth boundary. (3 to 8 cm thick)

C--8 to 28 cm; light yellowish brown (10YR 6/4) very gravelly loam, dark yellowish brown (10YR 4/4) moist; moderate fine subangular blocky structure; soft, very friable, slightly sticky and slightly plastic; many very fine, many fine, and few medium roots; common very fine and fine tubular pores; 12 percent cobbles and 35 percent gravel; violently effervescent; moderately alkaline (pH 8.0); abrupt wavy boundary. (8 to 25 cm thick)

R--28 cm; gray (10YR 5/1) limestone.

TYPE LOCATION: Lincoln County, Nevada; in the Burnt Springs Range about 0.25 mile south of U.S. Highway 93; approximately 2,500 feet west and 1,000 feet north of the projected southeast corner of section 7, T. 4 S., R. 65 E.; USGS Chokecherry Mountain 7.5 minute topographic quadrangle; latitude 37 degrees 36 minutes 37.9 seconds N and longitude 114 degrees 44 minutes 28 seconds W; WGS84 Decimal Degrees 37.6105278 latitude, -114.7411111 longitude.

RANGE IN CHARACTERISTICS:
Soil moisture: Usually moist in winter and spring, dry in summer and fall except intermittently moist in some part for 10 to 20 days cumulative between July and September due to convection storms; aridic soil moisture regime that borders on xeric.
Mean annual soil temperature: 11.5 to 15 degrees C.
Depth to bedrock: 15 to 36 cm.
Reaction: Moderately alkaline or strongly alkaline.
Effervescence: Strongly effervescent or violently effervescent.
Calcium carbonate equivalent: 30 to 40 percent in the fine-earth fraction and 40 to 60 percent in the less than 20 mm fraction.

Particle-size control section - Clay content: 7 to 18 percent.
Rock fragments: 35 to 60 percent. Lithology of fragments is limestone and dolomite.

A horizon
Value: 6 or 7 dry, 3 through 5 moist.
Chroma: 2 or 3, dry or moist.

C horizon
Hue: 10YR or 7.5YR.
Value: 6 or 7 dry, 4 or 5 moist.
Chroma: 2 through 4 moist.
Texture: Loam, fine sandy loam, very fine sandy loam, or silt loam.
Structure: Massive or subangular blocky.
Consistence: Soft or slightly hard dry, very friable or friable moist, slightly sticky or moderately sticky, slightly plastic or moderately plastic.
Rock fragments: Average 35 to 60 percent; Subhorizons have up to 70 percent rock fragments in some pedons.
Other features: Some pedons have a thin Bk horizon. Some pedons have faint secondary calcium carbonate concretions on rock fragments.

COMPETING SERIES: These are the Eaglepass, Izod, Kram, Logring, Tiki, and Zimbob series.

Eaglepass soils are less than 15 cm to bedrock and have 60 to 75 percent rock fragments. Izod soils have 18 to 25 percent clay in the particle-size control section. Kram soils are not moist for 10 to 20 days from July to September. Logring soils have 15 to 40 percent finely divided carbonates in the upper 18 cm and have Bk horizons. Tiki soils have hue of 2.5YR or 5YR. Zimbob soils are not moist for 10 to 20 days cumulative between July and September and have a mean annual soil temperature of 8.5 to 11 degrees C.

GEOGRAPHIC SETTING: Kyler soils are on mountains and hills. These soils formed in residuum and colluvium derived from limestone and dolomite. Slopes are 4 to 75 percent. Elevations range from 1,302 to 3,166 meters. The mean annual precipitation is 200 to 300 mm, the mean annual temperature is 10 to 12 degrees C, and the frost-free period is 100 to 130 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Eaglepass soil and the Ursine soil. Ursine soils have a duripan.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained; moderately high saturated hydraulic conductivity.

USE AND VEGETATION: Kyler soils are used for livestock grazing and wildlife habitat. The vegetation is mainly black sagebrush, Mexican cliffrose, needleandthread, Indian ricegrass, and Utah juniper.

DISTRIBUTION AND EXTENT: Eastern Nevada. These soils are extensive with about 305,000 acres of the series mapped to date. The series concept and main acreage is in MLRA 29, while other acreage occurs in MLRAs 28A and 28B.

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Davis, California.

SERIES ESTABLISHED: Lincoln County (Meadow Valley Area), Nevada, 1971.

REMARKS: Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon The zone from the soil surface to 18 cm (A and part of the C horizons).
Lithic contact - The boundary at 28 cm to underlying hard, unweathered bedrock (R layer).
Particle-size control section - The zone from the soil surface to 28 cm (A and C horizons).

The revision of August 2008 moved the type location from the Meadow Valley Area to the soil survey of Lincoln County, Nevada, South Part and a typical pedon that is more representative of the series.

ADDITIONAL DATA: A pedon of Kyler has full characterization data by the Soil Survey Laboratory (SSL), Lincoln, NE, as pedon ID S05NV-017-004 (pedon # 05N0665).
