KANLEE SERIES

The Kanlee series consists of moderately deep to soft weathered bedrock, well to somewhat excessively drained soils that formed in residuum and colluvium from schist, gneiss, quartz monzonite, granite or other coarse-grained intrusive acid igneous rock. Permeability is moderately slow. Kanlee soils are on hillsides, mountainsides, and terraces and have slopes of 1 to 55 percent. The average annual precipitation is about 430 mm and the average annual temperature is about 6.1 degrees C.

TAXONOMIC CLASS: Fine-loamy, mixed, superactive, frigid Typic Argixerolls

TYPICAL PEDON: Kanlee fine gravelly coarse sandy loam -- on a west-facing slope of 16 percent, in native rangeland at 1,710 meter elevation. (Colors are for air dry soil unless otherwise stated.)

(13 to 41 cm thick)

AB--25 to 36 cm; brown (10YR 4/3) fine gravelly coarse sandy loam, very dark brown (10YR 2/3) moist; weak fine and medium subangular blocky structure that parts to weak very fine and fine granular; slightly hard, very friable, slightly sticky and slightly plastic; many fine, few medium and coarse roots; many very fine interstitial and tubular pores; moderately micaceous; few faint clay films on faces of peds, in pores, and bridging between particles; 15 percent gravel; neutral (pH 6.6); clear wavy boundary. (0 to 33 cm thick)

Bt1--36 to 43 cm; brown (7.5YR 5/3) fine gravelly sandy clay loam, dark brown (10YR 3/3) moist; weak fine subangular blocky structure that parts to weak fine and medium granular; slightly hard, very friable, slightly sticky and slightly plastic; common fine and medium, few coarse roots; many fine tubular pores; moderately micaceous; few faint slightly darker clay films in pores, common faint clay films on faces of peds; 15 percent gravel; neutral (pH 6.7); clear broken boundary. (8 to 18 cm thick)

Bt2--43 to 61 cm; brown (7.5YR 5/4) fine gravelly sandy clay loam, dark brown (7.5YR 4/3) moist; moderate fine subangular blocky structure; hard, friable, slightly sticky and slightly plastic; common fine, few medium and coarse roots; common fine tubular pores; few faint clay films on faces of peds, in pores and few faint clay bridges between sand grains; 15 percent gravel; moderate to much mica; neutral (pH 6.7); clear irregular boundary. (13 to 23 cm thick)

Bt3--61 to 81 cm; brown (7.5YR 5/4) and light brown (7.5YR 6/5) fine gravelly sandy clay loam, dark brown (7.5YR 4/4) and brown (7.5YR 5/4) moist; moderate fine and very fine subangular blocky structure; slightly hard, friable, slightly sticky and slightly plastic; few fine and medium roots; many fine and very fine tubular pores; common distinct and faint clay films on faces of peds, in pores, and bridging between particles; one or more very thin horizontal more clayey bands (lamellae); 30 percent gravel; neutral (pH 6.7); clear irregular boundary. (15 to 25 cm thick)

Cr--81 to 114 cm; weathered granite with much brown staining; few pockets or streaks of fine gravelly sandy clay loam resembling that in the B3t horizon; one or more very thin horizontal clayey bands (lamellae); neutral (pH 6.7); gradual broken boundary.

R--114 cm; fractured, partly weathered granite.

COMPETING SERIES: These are the Alexander (T), Ayoub, Cloudless, Cloud Rim, Isbell, Maple Mountain, Paynecreek and Ticino series. Alexander and Ayoub soils lack Cr horizons and are moderately deep over basalt. Cloudless soils are very deep. Cloud Rim soils have a solum thickness of 127 to 152 cm. Isbell, Maple Mountain, and Paynecreek soils are over 100 cm deep to bedrock. Ticino soils lack coarse sands in the fine earth fraction and are dry for more than 70 days in the moisture control section.

GEOGRAPHIC SETTING: Kanlee soils are on mountainsides, hillsides and terraces at elevations of 4,600 to 7,000 feet. They formed in residuum and colluvium from schist, gneiss, quartz monzonite, granite or related coarse-grained intrusive acid igneous rock. Slopes range from 1 to 55 percent. The climate is subhumid. Average annual precipitation is 13 to 25 inches, and average annual temperature is 40 to 45 degrees F. Frost-free period is 55 to 100 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Itca, Ola, Poisoncreek (T), and Takeuchi soils. Itca and Poisoncreek soils are less than 20 inches deep over bedrock. Ola and Takeuchi soils lack Bt horizons. These soils are on hillsides and mountainsides.

DRAINAGE AND PERMEABILITY: Well drained; medium or rapid runoff; moderately slow permeability.

USE AND VEGETATION: Kanlee soils are used mainly for rangeland and pasture; minor areas are used for hayland and small grains. Dominant natural vegetation is bluebunch wheatgrass, Idaho fescue, Sandberg bluegrass, big sagebrush, and Antelope bitterbrush.

DISTRIBUTION AND EXTENT: Southwestern and south central Idaho. The series is moderately extensive. MLRA 25.
