TAXONOMIC CLASS: Fine-silty, mixed, superactive, calcareous, thermic Typic Torrifluvents
TYPICAL PEDON: Glendale loam - rangeland. (Colors are for dry soil unless otherwise noted.)
A--0 to 8 inches; light brownish gray (10YR 6/2) loam, brown (10YR 4/3) moist; weak medium platy structure parting to massive; slightly hard, friable, slightly sticky and slightly plastic; common very fine roots; few very fine and fine irregular pores; strongly effervescent; moderately alkaline (pH 8.0); abrupt smooth boundary. (6 to 12 inches thick)
Ck1--8 to 18 inches; grayish brown (10YR 5/2) clay loam, dark grayish brown (10YR 4/2) moist; weak fine and coarse subangular blocky structure; very hard, friable, slightly sticky and moderately plastic; few very fine and fine roots; few very fine and fine tubular and few fine irregular pores; common very fine and fine irregular accumulations of calcium carbonate; strongly effervescent; moderately alkaline (pH 8.0); clear smooth boundary. (10 to 30 inches thick)
Ck2--18 to 60 inches; grayish brown (10YR 5/2) stratified silty clay loam, brown (10YR 4/3) moist; massive; very hard, friable, moderately sticky and moderately plastic; few very fine and fine roots; few very fine tubular pores; common very fine and fine irregular accumulations of calcium carbonate; strongly effervescent; moderately alkaline (pH 8.0).
TYPE LOCATION: Graham County, Arizona; about 5 miles south of Safford; 400 feet east and 2,640 feet south of the northwest corner of Section 5, T. 8 S., R. 26 E.
RANGE IN CHARACTERISTICS:
Soil Moisture: Intermittently moist in some part of the soil moisture control section during July-September and December-February. Driest during May and June. Typic aridic soil moisture regime.
Rock Fragments: Usually nongravelly, but may range to 35 percent in any one horizon
Organic Matter: Less than 1 percent that decreases irregularly with depth
Stratification: Usually less than 1 inch thick strata of finer or coarser material
A horizon
Hue: 7.5YR, 10YR
Value: 5, 6 or 7 dry, 3, 4 or 5 moist
Chroma: 2, 3 or 4, dry or moist
C horizon
Hue: 7.5YR, 10YR
Value: 4 through 7 dry, 3 through 6 moist
Chroma: 2, 3 or 4, dry or moist
Texture: Loam, silt loam, clay loam, silty clay loam
Reaction: Neutral to strongly alkaline
Calcium carbonate: Slightly to violently effervescent as disseminated or fine irregular accumulations
Buried horizons: A buried argillic horizon is present at depths greater than 40 inches in some pedons.
COMPETING SERIES: These are the Pima (AZ) and Rift (AZ) series. Pima soils have more than 1 percent organic matter to depths of 20 inches or more. Rift soils are moist in the soil moisture control section for less than 20 days cumulative during July-September and occur in MLRA 30 of the Mohave Desert.
GEOGRAPHIC SETTING: Glendale soils are on alluvial fans and flood plains at elevations of 1,500 to 5,100 feet. These soils formed in stratified alluvium from mixed sources. Slopes range from 0 to 5 percent. The mean annual precipitation is 4 to 12 inches. The mean annual air temperature is 57 to 70 degrees F. The frost-free period is 180 to 280 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Anthony, Brazito, Gila, Grabe, Hantz and the competing Pima soils. Anthony, Gila, and Grabe soils are coarse-loamy. Arizo soils are sandy-skeletal. Brazito soils are sandy. Hantz soils are fine.
DRAINAGE AND PERMEABILITY: Well drained; medium runoff; moderately slow permeability.
USE AND VEGETATION: Glendale soils are used for livestock grazing and irrigated cropland. The present vegetation is creosotebush, mesquite, palo verde, ironwood, salt cedar, cacti, annual forbs and grasses.
DISTRIBUTION AND EXTENT: Arizona, Nevada, California and New Mexico. This series is extensive. This soil occurs in LRR-D, MLRAs 40, 41, and 42. Use in California and Nevada should be discontinued.
MLRA OFFICE RESPONSIBLE: Phoenix, Arizona
SERIES ESTABLISHED: Maricopa County (Queen Creek SCD), Arizona; 1946.
REMARKS: Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon - The zone from 0 to 8 inches (A horizon)
Entisol feature - The absence of diagnostic subsurface horizons
Fluvial feature - Irregular decrease in organic carbon in the zone from 8 to 60 inches (Ck1, Ck2 horizons)
Classified according to Soil Taxonomy Second Edition, 1999.
