KLEINBUSH SERIES

The Kleinbush series consists of very deep, well drained soils that formed in alluvium derived from basalt. Kleinbush soils are on alluvial fans and have slopes of 0 to 15 percent. The mean annual precipitation is about 180 mm and the mean annual temperature is about 10 degrees C.

TAXONOMIC CLASS: Fine, smectitic, mesic Typic Natrargids

TYPICAL PEDON: Kleinbush very cobbly loamy sand--rangeland. (Colors are for dry soil unless otherwise noted.) The surface is covered with 10 percent gravel, 40 percent cobbles, and a few stones.

(10 to 20 cm thick)

4Btkb1--48 to 76 cm; reddish yellow (7.5YR 6/6) clay loam, strong brown (7.5YR 5/6) moist; strong medium prismatic structure; hard, friable, moderately sticky and moderately plastic; common fine and medium dead roots; common very fine and fine tubular pores; few thin clay film lining pores; strongly effervescent; moderately alkaline (pH 8.2); gradual smooth boundary. (0 to 38 cm thick)

4Btkb2--76 to 97 cm; reddish yellow (7.5YR 6/6) clay, brown (7.5YR 5/4) moist; massive; slightly hard, very friable; slightly sticky and slightly plastic; few fine dead roots; few very fine and fine tubular pores; few thin clay films lining pores; violently effervescent; moderately alkaline (pH 8.2); abrupt smooth boundary. (0 to 25 cm thick)

5Bk--97 to 152 cm; pinkish gray (7.5YR 7/2) cobbly sandy clay loam, light brown (7.5YR 6/4) moist; massive; slightly hard, very friable, slightly sticky and slightly plastic; 5 percent gravel and 10 percent cobbles; many medium irregular shaped lime filaments; violently effervescent; moderately alkaline (pH 8.4).

COMPETING SERIES: These are the Buckaroo, Calneva, Effington, Meeteetse, Ultra, and Uvada.

Buckaroo soils have an SAR of 31 to 90 and depth to base of natric horizon is 25 to 50 cm. Calneva soils have less than 15 percent sand in the natric horizon and stratified 2C horizons. Effington soils are calcareous at or near the surface and have weak structure in the Bt horizon. Meeteetse soils are calcareous at or near the surface and have a moderate amount of gypsum in the lower part of the argillic and the C horizon. Ultra soils have the base of the natric horizon at 18 to 33 cm. Uvada soils are calcareous throughout and have a silty clay loam or silty clay natric horizon.

GEOGRAPHIC SETTING: Kleinbush soils are on alluvial fans at elevations of 1,345 to 2,135 meters. These soils formed in alluvium from mixed rock. The climate is arid with mild winters and hot summers. Slopes are 0 to 15 percent. The mean annual precipitation is 130 to 200 mm; mean annual temperature is 9 to 11 degrees C; and the frost-free season is about 100 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bundorf and Sutcliff soils. Bundorf soils have an indurated duripan within 50 cm of the surface. Sutcliff soils have more than 35 percent rock fragments and less than 35 percent clay in the particle-size control section.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained, medium runoff; slow permeability; moderately low saturated hydraulic conductivity.

USE AND VEGETATION: These soils are used for range and wildlife. The native vegetation is bud sagebrush, winterfat, shadscale, spiny hopsage, Indian ricegrass, bottlebrush squirreltail and scarlet globemallow.

DISTRIBUTION AND EXTENT: Southern Washoe County, Nevada. They are of small extent. MLRA 27.
