Bt2--18 to 28 inches; brown (7.5YR 5/4) loam, dark brown (7.5YR 4/4) moist; moderate coarse subangular blocky structure; slightly hard, friable, slightly sticky and plastic; few very fine and fine roots; common very fine tubular pores; common thin clay films on faces of peds; 10 percent pebbles; medium acid (pH 5.6); clear wavy boundary. (0 to 15 inches thick)
R--28 inches; fractured tuff.
TYPE LOCATION: Elko County, Nevada, about 4 miles east of Owyhee, 1,200 feet north and 100 feet east of the southwest corner of section 16, T. 47 N., R. 53 E.
RANGE IN CHARACTERISTICS:
Soil moisture - Usually moist, dry in late July through early October.
Mean annual soil temperature - 36 to 42 degrees F.
Mean summer soil temperature - 55 to 59 degrees F.
Depth to bedrock - 20 to 40 inches.
Cambic horizon (Bt) - Horizon always has evidence of clay movement, but does not have the necessary clay increase required for a argillic horizon.
Base saturation by sum of cations - 50 to 75 percent.
A horizon - Hue: 5YR or 10YR.
Value: 3 through 5 dry, 2 or 3 moist.
Chroma: 2 through 4 dry, 1 or 2 moist.
Rock fragments: 0 to 10 percent.
Reaction: Slightly acid to strongly acid.
Bt horizon - Hue: 7.5YR or 10YR.
Value: 2 through 4 moist, 4 or 5 dry.
Chroma: 3 or 4.
Texture: Loam or cobbly loam.
Clay content: 18 to 27 percent.
Rock fragments: 5 to 30 percent.
Reaction: Slightly acid through strongly acid.
COMPETING SERIES: These are the Adel, Bullbasin(T), Bullrey, Duff, Gallatin, Hackwood, Idmon(T), Karlan, Lamphier, Leavittville, Lespate(T), Mundos, Osmund, Pavohroo, Rhone, Secondset(T), Taterheap(T) and Winevada series. Adel, Bullbasin, Bullrey, Duff, Gallatin, Hackwood, Idmon, Lamphier, Leavittville, Mundos, Osmund, Pavohroo, Rhone and Taterheap soils have bedrock at a depth of 40 inches or more. Karlan, Leavittville, Mundos, and Osmund soils have a Bk horizon. Lespate soils have Bw horizons, and have Bk horizon above bedrock and lack evidence of clay films. Secondset soils do not have Bt horizon and have mollic epipedon that are greater than 18 inches thick. Winevada soils lack a Bt horizon and lack clay films on peds and have a paralithic.
GEOGRAPHIC SETTING: Strickland soils are on concave side slopes of basalt plateaus, mountains and hills. These soils formed in colluvium or alluvium derived from basalt and tuff. Slopes are 2 to 30 percent. Elevations are 6,000 to 7,600 feet. The mean annual precipitation is 18 to 22 inches; mean annual temperature is 35 to 40 degrees F., and the frost-free season is 20 to 50 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bluebell, Dranyon, Parkay, and Tusel soils. Bluebell soils are on convex hilltops and hill slopes. Dranyon, Parkay, and Tusel soils are on concave hill slopes. Bluebell and Parkay soils have a loamy-skeletal argillic horizon. Dranyon and Tusel soils have an argillic horizon.
DRAINAGE AND PERMEABILITY: Well drained; slow to rapid runoff; moderate permeability.
USE AND VEGETATION: Rangeland and wildlife habitat. Vegetation is mainly mountain big sagebrush, western snowberry, serviceberry, common chokecherry, mountain brome, slender wheatgrass, and mulesear wyethia.
DISTRIBUTION AND EXTENT: North-central Nevada and southwestern Idaho. The soils are not extensive.
