KLECK SERIES

The Kleck series consists of well drained soils that are shallow over consolidated lake sediments. The soils formed in lacustrine sediments influenced by eolian sand or loess. The Kleck soils are on basin-floor remnants, lake plains and lake-plain terraces. Slopes are 0 to 2 percent. The mean annual precipitation is about 230 mm and the mean annual temperature is about 10 degrees C.

TAXONOMIC CLASS: Loamy, mixed, superactive, mesic, shallow Xeric Haplocambids

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

A--0 to 8 cm; light brownish gray (2.5Y 6/2) loamy fine sand, dark grayish brown (2.5Y 4/2) moist; weak coarse prismatic structure parting to moderate medium subangular blocky; soft, very friable, nonsticky and nonplastic; common very fine and fine roots; many very fine interstitial pores; slightly alkaline (pH 7.4); abrupt wavy boundary. (8 to 18 cm thick)

2Bw1--8 to 20 cm; variegated light gray (2.5Y 7/2) and grayish brown (10YR 5/2) clay loam, olive brown (2.5Y 4/4) moist; moderate coarse prismatic structure parting to moderate thin platy; slightly hard, very friable, slightly sticky and slightly plastic; common very fine, fine and medium roots; common very fine and fine tubular and interstitial pores; 10 percent 5 to 13 cm diameter fine sandy loam krotovinas; slightly alkaline (pH 7.8); clear wavy boundary. (0 to 15 cm thick)

2Bw2--20 to 28 cm; yellowish brown (10YR 5/4) clay loam, olive brown (2.5Y 4/4) moist; common dark yellowish brown (10YR 4/4) stains on face of peds; moderate coarse prismatic structure parting to moderate thin platy; hard, friable, moderately sticky and moderately plastic; common very fine and fine and few medium and coarse roots; common very fine, fine and medium tubular pores; common thin silica lamella bridging sand grains; moderately alkaline (pH 8.2); clear wavy boundary. (8 to 30 cm thick)

2Bk--28 to 38 cm; light yellowish brown (2.5Y 6/4) light gray (10YR 7/2) crushed, silty clay loam, light olive brown (2.5Y 5/4) moist; few fine distinct yellowish brown (10YR 5/6) and brownish yellow (10YR 6/8) relic mottles; weak coarse prismatic structure parting to moderate thin platy; slightly hard, friable, slightly sticky and slightly plastic; common very fine and fine and few medium roots; common very fine and fine tubular pores; 35 percent very hard fragments and nodules of consolidated lake sediments; few fine carbonate filaments; slightly effervescent; strongly alkaline (pH 8.6); clear wavy boundary. (8 to 23 cm thick)

2Cd--38 to 152 cm; light gray (2.5Y 7/2) fractured consolidated lake sediments, grayish brown (2.5Y 5/2) moist; massive; very hard and firm; few very fine and fine roots oriented horizontally and vertically only in fractures; many thin white (10YR 8/1) stains on fracture planes.

TYPE LOCATION: Humboldt County, Nevada; approximately 5 miles west of Winnemucca and 1.5 miles south of Jungo Road, about 1,500 feet north and 300 feet east of the southwest corner of section 32, T. 36 N., R. 37 E.; USGS Winnemucca West 7.5 minute topographic quadrangle; latitude 40 degrees 56 minutes 57 seconds N and longitude 117 degrees 50 minutes 52 seconds W; WGS84 Decimal Degrees 40.9491667 latitude, 40.9491667 longitude.

A horizon
Hue: 10YR or 2.5Y.
Value: 6 or 7 dry, 4 or 5 moist.
Chroma: 2 through 4.
Reaction: Slightly alkaline or moderately alkaline.
Other features: Normally noneffervescent but may be effervescent in some pedons due to recharge from dust.

Bw horizons
Hue: 10YR or 2.5Y.
Value: 5 through 7 dry, 4 or 5 moist.
Chroma: 2 through 4.
Texture: Stratified silt loam, silty clay loam and clay loam; some pedons have krotovinas and thin subhorizons of loamy fine sand or very fine sandy loam.
Structure: Subangular blocky, platy or is prismatic.
Consistence: Slightly hard, or hard, dry.
Reaction: slightly alkaline or moderately alkaline.
Other features: Normally noneffervescent but is effervescent in some pedons due to recharge from dust.

Bk horizon
Hue: 10YR or 2.5Y.
Value: 6 through 8 dry, 4 through 6 moist.
Chroma: 2 through 4.
Texture: Stratified silty clay loam, and silt loam.
Structure: Platy, prismatic or is massive.
Consistence: Slightly hard or hard, dry.
Reaction: Moderately alkaline through very strongly alkaline.
Other features: Horizon has 5 to 35 percent, hard or very hard and firm or very firm fragments and nodules of consolidated lake sediments.

Cd horizon
Hue: 10YR or 2.5Y.
Value: 7 or 8 dry, 5 or 6 moist.
Chroma: 1 or 2.
Consistence: Very hard or extremely hard dry, firm or very firm moist.

COMPETING SERIES: There are no competing series.

GEOGRAPHIC SETTING: Kleck soils are on lake plains, lake-plain terraces and basin floor remnants. These soils formed in lacustrine sediments influenced by eolian sand or loess. Slopes are 0 to 2 percent. Elevations are 1,250 to 1,345 meters. The climate is cool, semiarid with cool, moist winters and warm, dry summers. The mean annual precipitation is 200 to 250 mm, mean annual temperature is 7 to 10 degrees C, and the frost-free season is 90 to 120 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Batan, Goldrun and Davey series. All of these soils are very deep. In addition, Batan soils lack a cambic horizon. Goldrun and Davey soils have a sandy particle-size control section.

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

USE AND VEGETATION: Irrigated cropland, rangeland and wildlife habitat. The present vegetation is mainly basin big sagebrush, Indian ricegrass, Eriogonum, rubber rabbitbrush, bottlebrush squirreltail, needleandthread and cheatgrass.

DISTRIBUTION AND EXTENT: North-central Nevada. Kleck soils are not extensive. MLRA 24.
