HATRANCH SERIES
The Hatranch series consists of very deep, well drained soils that formed in lacustrine sediments. The Hatranch soils are on fan remnants and have slopes of 3 to 60 percent. The mean annual precipitation is about 13 inches and the mean annual air temperature is about 62 degrees F.
TAXONOMIC CLASS: Fine-silty, mixed, superactive, calcareous, thermic Ustic Torriorthents
TYPICAL PEDON: Hatranch silty clay loam-rangeland. (Colors are for dry soil unless otherwise noted.)
A--0 to 4 inches; light brownish gray (2.5Y 6/2) silty clay loam, brown (10YR 5/3) moist; weak medium subangular blocky structure; soft, very friable, moderately sticky and very plastic; many very fine and fine roots; many fine and medium tubular pores; slightly effervescent; strongly alkaline (pH 8.6); clear smooth boundary. (2 to 5 inches thick)
C1--4 to 16 inches; light brownish gray (2.5Y 6/2) silty clay loam, light brownish gray (10YR 6/2) moist; strong medium subangular blocky structure; slightly hard, very friable, very sticky and very plastic; common very fine through medium roots; common fine tubular pores; strongly effervescent; strongly alkaline (pH 8.6); clear irregular boundary. (10 to 14 inches thick)
C2--16 to 33 inches; light gray (10YR 7/2) silty clay loam, brown (10YR 5/3) moist; strong medium angular blocky structure; very hard, firm, moderately sticky and moderately plastic; common very fine through medium roots; few very fine tubular pores; common medium distinct yellowish brown (10YR 5/6) relict mottles; noneffervescent; strongly alkaline (pH 8.6); clear wavy boundary. (14 to 20 inches thick)
Cy--33 to 60 inches; light gray (5Y 7/2) silty clay, light olive gray (5Y 6/2) moist; strong medium angular blocky structure; very hard, very firm, very sticky and very plastic; few fine roots; few very fine tubular pores; common fine gypsum crystals; noneffervescent; strongly alkaline (pH 8.6).
TYPE LOCATION: Yavapai County, Arizona; located about 1340 feet south and 2955 feet west of the northeast corner of sec 20, T. 13 N., R. 5 E.; 34 degrees, 30 minutes, 24.6 seconds north latitude and 111 degrees, 50 minutes, 35.0 seconds west longitude.
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. Ustic aridic soil moisture regime.
Soil temperature: 62 to 65 degrees F.
Rock Fragments: Averages less than 5 percent in the particle-size control section
Clay content: Averages 30 to 35 percent in the particle-size control section
Calcium carbonate equivalent: 2 to 30 percent
Gypsum content: 10 to 35 percent by weight
Redoximorphic features: Highly variable throughout and are related to the past lacustrine environment.
A horizon
Hue: 2.5Y, 10YR
Value: 5 or 6 dry, 4 or 5 moist
Chroma: 3 or 4, dry or moist
Electrical Conductivity: 0 to 2 dS/m
C horizons
Hue: 5Y, 2.5Y, 10YR, 7.5YR
Value: 5 through 7, dry or moist
Chroma: 2 through 4, dry or moist
Textures: silty clay, silty clay loam
Electrical conductivity: 2 to 8 dS/m
COMPETING SERIES: This is the
Lacita (NM) series. Lacita soils formed in sediments derived from redbed formations and have hues 7.5YR and redder. In addition, Lacita soils are in LRR-G MLRA 70 and are more moist in
May and June.
GEOGRAPHIC SETTING: Hatranch soils are on fan remnants. They formed in residuum from gypsiferous lacustrine sediments of the Verde Formation. Slopes range from 3 to 60 percent. Elevations range from 3000 to 4000 feet. The mean annual precipitation is 12 to 14 inches and the mean annual air temperature is 60 to 63 degrees F. The frost-free period is 180 to 220 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Ryallen and the
Bewearze soils. Ryallen soils have an argillic horizon and are clayey-skeletal. Bewearze soils are coarse-silty and have a cambic horizon.
DRAINAGE AND PERMEABILITY: Well drained; medium to very rapid runoff; very slow permeability.
USE AND VEGETATION: Hatranch soils are used for urban land and wildlife habitat. Vegetation consists of canotia, mesquite, mimosa, algerita, scattered juniper, cliffrose, threeawn, and needleandthread.
DISTRIBUTION AND EXTENT: Central Arizona. Hatranch soils are of very little extent. This soil occurs in LRR-D, MLRAs 38 and 40. The name is derived from a nearby ranch.
