COMPETING SERIES: These are the Adkins, Bijorja, Chedehap, Clems, Drewsey, Haybourne, Irrigon, McClenden, Prosser, Rebel, Royal, Scooteney, Sohappy, and Wiehl series. Adkins, Chedehap, Clems, Drewsey, Haybourne, McClenden, Rebel, Royal, and Scooteney are more than 40 inches deep to a lithic or a paralithic contact. Bijorja and Irrigon have mean annual soil temperatures of 53 degrees F. or more. Wiehl are over a paralithic contact. Prosser soils have a very fine sandy loam control section. Sohappy soils are deep to a duripan.
GEOGRAPHIC SETTING: Vining soils are on level to hilly basalt plains and terraces covered by eolian and alluvial material of mixed origin. Most slopes are short and irregular. Slopes range from 0 to 30 percent, but are principally from 2 to 15 percent. Elevations range from 2,500 to 5,000 feet. The climate is semiarid and has relatively dry summers. Average annual precipitation is 8 to 12 inches, and the average annual air temperature is 45 to 51 degrees F. Frost free season is 80 to 140 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Escalante, Portneuf, Quincy, Royal, and Trevino soils. All of these except Trevino are deeper than 40 inches. Trevino soils are less than 20 inches deep to bedrock. These soils are all on landscape positions similar to Vining soils.
DRAINAGE AND PERMEABILITY: Well drained, slow or medium runoff; moderately rapid permeability.
USE AND VEGETATION: Used primarily for rangeland. Vegetation in the potential natural plant community is mainly Wyoming big sagebrush, Thurber needlegrass, Indian ricegrass, and bluebunch wheatgrass.
DISTRIBUTION AND EXTENT: Southern Idaho and Southeastern Oregon. The series is moderately extensive.
