COMPETING SERIES: These are the Arbidge, Dacker, Deerlodge, Ditchcamp, Drysel, Excel, Hager, Idow (T), Lembos, Ochoco, Rakane (T), Snowmore, Wako (T), and Wellsed soils. Arbidge, Dacker, Deerlodge, Drysel, Excel, Hager, Idow, Ochoco, Rakane, Wako, and Wellsed soils are 40 or more inches to bedrock. Ditchcamp soils have 30 to 35 percent clay in the control section. Lembos soils are calcareous in the argillic horizon. Snowmore soils are mildly to moderately alkaline in the argillic horizon and have moderately slow permeability.
GEOGRAPHIC SETTING: Wendell soils are on basalt plains. These soils formed in eolian material that has been reworked by water. Slopes are 1 to 12 percent. Elevation is 3,200 to 4,200 feet. The average annual precipitation is 9 to 11 inches. The average annual temperature is 48 to 51 degrees F. and the frost-free period is 100 to 120 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Harsan (T), Kecko, Quincy, Taunton, Jestrick, and Wako (T) soils. Harsan, Kecko, Quincy, Taunton, and Wako soils have bedrock below 40 inches. Jestrick soils lack an argillic horizon. These soils are on basalt plains near the Wendell soils.
DRAINAGE AND PERMEABILITY: Well drained; runoff is slow to moderate; permeability is moderate.
USE AND VEGETATION: Wendell soils are used for rangeland and irrigated crops. Native vegetation is basin big sagebrush, bluebunch wheatgrass, Indian ricegrass, Thurber needlegrass, and needleandthread.
DISTRIBUTION AND EXTENT: Wendell soils are of small extent in south central Idaho.
