POODLE SERIES
The Poodle series consists of moderately deep, well drained soils that formed in residuum and colluvium derived from granitic rocks with surficial additions of loess. Poodle soils are on mountains. Slopes are 2 to 30 percent. The mean annual precipitation is about 400 mm and the mean annual temperature is about 6 degrees C.
TAXONOMIC CLASS: Fine-loamy, mixed, superactive Pachic Argicryolls
TYPICAL PEDON: Poodle loam--rangeland. (Colors are for dry soil unless otherwise noted.)
A--0 to 13 cm; dark grayish brown (10YR 4/2) loam, very dark brown (10YR 2/2) moist; moderate medium subangular blocky structure; soft, very friable, slightly sticky and nonplastic; many very fine roots; common very fine interstitial pores; neutral (pH 6.6); abrupt smooth boundary. (5 to 42 cm thick)
Bt1--13 to 36 cm; brown (10YR 4/3) loam, very dark brown (10YR 2/2) moist; strong fine and medium subangular blocky structure; slightly hard, very friable, slightly sticky and slightly plastic; common very fine and fine, few medium roots; common very fine tubular pores; many faint clay films on faces of peds and lining pores; 5 percent gravel; neutral (pH 6.8); gradual wavy boundary. (15 to 30 cm thick)
Bt2--36 to 69 cm; brown (10YR 4/3) loam, very dark grayish brown (10YR 3/2) moist; strong fine and medium subangular blocky structure; hard, friable, slightly sticky and slightly plastic; common very fine and few fine roots; common very fine tubular pores; many faint clay films on faces of peds and lining pores; 5 percent gravel; neutral (pH 6.8); gradual smooth boundary. (15 to 38 cm thick)
Bt3--69 to 89 cm; brown (10YR 4/3) sandy loam, very dark grayish brown (10YR 3/2) moist; weak medium subangular blocky structure; hard, friable, slightly sticky and slightly plastic; few fine roots; common very fine tubular pores; common faint clay films on faces of peds and lining pores; 5 percent gravel; neutral (pH 6.8); abrupt smooth boundary. (10 to 28 cm thick)
Cr--89 cm; weathered quartz monzonite.

RANGE IN CHARACTERISTICS:
Soil moisture: Usually moist in winter and early spring, dry in late summer and fall; xeric soil moisture regime that borders on aridic.
Mean annual soil temperature: 6 to 8 degrees C.
Mean summer soil temperature: 12 to 15 degrees C.
Mollic epipedon thickness: 50 to 100 cm; includes the Bt horizons.

GEOGRAPHIC SETTING: Poodle soils are on mountains. They typically occur on summit and shoulder positions. These soils formed in residuum and colluvium derived from granitic rocks with surficial additions of loess. Slopes are 2 to 30 percent. Elevations range from 1,955 to 2,780 meters. The climate is semiarid with cold, moist winters and cool, dry summers. The mean annual precipitation is 360 to 460 mm, the mean annual temperature is 4 to 7 degrees C, and the frost-free period is 30 to 70 days.
GEOGRAPHICALLY ASSOCIATED SOILS: This is the
Tosp soil. Tosp soils do not have bedrock within 100 cm.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained; low or medium surface runoff; moderately high saturated hydraulic conductivity.
USE AND VEGETATION: Poodle soils are used for rangeland and wildlife habitat. The present vegetation is mainly mountain big sagebrush, snowberry, basin wildrye, bluegrass, and bluebunch wheatgrass.
DISTRIBUTION AND EXTENT: Northwestern Nevada. These soils are not extensive with about 2,200 acres of the series mapped to date. MLRA 23.
