COMPETING SERIES: These are the Jacques (AZ) and Rune (AZ) series. Jacques soils have hue of 7.5YR or yellower and have an aridic ustic soil moisture regime. Rune soils have hue of 5YR or redder.
GEOGRAPHIC SETTING: Bagley soils are on flood plains and have slopes of 0 to 3 percent. These soils formed in mixed alluvium. Elevations range from 5,000 to 6,500 feet. The mean annual precipitation ranges from 10 to 14 inches. The mean annual air temperature is 49 to 54 degrees F. The frost-free period is 130 to 160 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Claysprings, Tours and Trail soils. Claysprings soils have bedrock at depths less than 20 inches. Tours soils are fine-silty and Trail soils are sandy.
DRAINAGE AND PERMEABILITY: Well drained; slow runoff; slow or moderate permeability.
USE AND VEGETATION: Bagley soils are used for livestock grazing and irrigated cropland. The present vegetation is alkali sacaton, vine mesquite, bottlebrush squirreltail, Indian ricegrass, galleta, spike dropseed, blue grama and fourwing saltbush.
DISTRIBUTION AND EXTENT: Northern Arizona. This series is of small extent.
