STUCKY SERIES
The Stucky series consists of very deep, well drained soils formed in alluvium derived mainly from granitic rocks. These soils are on alluvial fans. Slopes are 2 to 30 percent. Mean annual temperature is about 9 degrees C and mean annual precipitation is about 200 mm.

GEOGRAPHIC SETTING: Stucky soils are on old stable alluvial fans with plane and convex surfaces. Slopes are 2 to 30 percent. The soils formed in alluvium derived mainly from granitic rock. The mean annual temperature is 9 to 10 degrees C, and the mean annual precipitation is 200 to 250 mm. Elevations are 1,400 to 2,134 meters. Frost-free season is 100 to 120 days.
GEOGRAPHICALLY ASSOCIATED SOILS: This is the competing

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained; slow or medium runoff; moderately slow saturated hydraulic conductivity.
USE AND VEGETATION: Used for livestock grazing and wildlife habitat. Vegetation is mainly low sagebrush and Indian ricegrass.
DISTRIBUTION AND EXTENT: Stucky soils are of small extent in the valleys of Western Nevada. MLRA 26.
