AKLER SERIES

The Akler series consists of shallow, well drained soils that formed in residuum derived from tuff, welded tuff, conglomerate and other volcanic or sedimentary rocks. Akler soils are on hills and mountains. Slopes are 2 to 50 percent. The mean annual precipitation is about 280 mm and the mean annual temperature is about 6 degrees C.

TAXONOMIC CLASS: Clayey, smectitic, frigid, shallow Xeric Haplargids

TYPICAL PEDON: Akler loam--rangeland. (Colors are for dry soil unless otherwise noted.) The soil surface is partially covered with 15 percent gravel.

A1--0 to 5 cm; light brownish gray (10YR 6/2) loam, dark grayish brown (10YR 4/2) moist; moderate fine and medium platy structure; slightly hard, very friable, slightly sticky and slightly plastic; common very fine roots; many very fine and fine vesicular pores; 10 percent gravel; slightly alkaline (pH 7.5); clear wavy boundary. (2 to 15 cm thick)

A2--5 to 15 cm; pale brown (10YR 6/3) clay loam, very dark grayish brown (10YR 3/2) moist; weak very fine platy structure; slightly hard, very friable, moderately sticky and moderately plastic; many very fine, few fine and medium roots; common very fine interstitial pores; few thin clay films on faces of ped along the lower boundary; 5 percent gravel; neutral (pH 7.3); abrupt smooth boundary. (0 to 10 cm thick)

Bt--15 to 43 cm; brown (10YR 5/3) clay, dark grayish brown (10YR 4/2) moist; strong medium prismatic structure; very hard, very firm, very sticky and very plastic; common fine and very fine roots; common very fine interstitial pores; many stress surfaces along faces of ped ; 10 percent gravel; neutral (pH 7.1); clear wavy boundary. (20 to 36 cm thick)

Cr1--43 to 71 cm; light brownish gray (2.5Y 6/2) fractured weathered tuff, light olive brown (2.5Y 5/4) moist; few very fine roots and few faint clay films along fracture planes; slightly alkaline (pH 7.6); clear wavy boundary. (20 to 38 cm thick)

Cr2--71 cm; white (5Y 8/1) weathered tuff, pale yellow (5Y 7/3) moist.

TYPE LOCATION: Elko County, Nevada; approximately 8 miles southeast of Taylor Canyon; about 600 feet north and 550 feet west of the southeast corner of section 24 T. 39 N., R. 53 E.; USGS Mahala Creek West 7.5 minute topographic quadrangle; latitude 41 degrees 15 minutes 02 seconds N and longitude 115 degrees 56 minutes 58 seconds W; WGS84 Decimal Degrees 41.2505556 latitude, -115.9494444 longitude.

RANGE IN CHARACTERISTICS:
Soil moisture: Usually dry, moist in the winter and spring dry mid-June through October; aridic soil moisture regime bordering on xeric.
Mean annual soil temperature: 7 to 8 degrees C.
Depth to paralithic contact: 36 to 50 cm.
Reaction: Neutral or slightly alkaline

Particle size control section - Clay content: 50 to 60 percent.
Rock fragments: 0 to 15 percent, mainly gravel with some pedons having 15 to 35 percent gravel and some pedons near rock outcrops having cobbles in their profile.

A horizon
Value: 5 or 6 dry, 3 or 4 moist.
Chroma: 2 or 3.

Bt horizon
Hue: 2.5Y or 10YR.
Value: 5 or 6 dry, 3 through 5 moist.
Chroma: 2 through 4.
Structure: Prismatic or subangular blocky in the lower part in some pedons.

Cr horizon
Clay films: Few common in upper horizon along fracture planes.

COMPETING SERIES: There are no competing series.

GEOGRAPHIC SETTING: Akler soils are on hills and mountains. Slopes are 2 to 50 percent. Elevations are 1,525 to 2,290 meters. These soils formed in residuum derived from tuff, welded tuff, conglomerate and other volcanic or sedimentary rocks. The climate is cool, semiarid with warm, dry summers and cool, moist winters. The mean annual precipitation is 250 to 300 mm; mean annual temperature is 4 to 7 degrees C, and the frost-free season is 70 to 100 days.

GEOGRAPHICALLY ASSOCIATED SOILS: This is the Eboda soils. Eboda soils have a mollic epipedon, a fine-loamy particle-size control section and have weathered tuff at a depth of 58 to 100 cm.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained; medium or rapid runoff; moderately low saturated hydraulic conductivity.

USE AND VEGETATION: Rangeland and wildlife habitat. The present vegetation is mainly low sagebrush, Douglas rabbitbrush, Thurber needlegrass, bottlebrush squirreltail and cheatgrass.

DISTRIBUTION AND EXTENT: Northeastern Nevada. MLRA 25, 28B. These soils are not extensive.
