LOCATION SANDRIDGE CAEstablished Series
TAXONOMIC CLASS: Siliceous, thermic Typic Torripsamments
TYPICAL PEDON: Sandridge loamy fine sand, on a smooth slope of 1 percent under red brome and saltgrass at 212 feet elevation. (Colors are for dry soil unless otherwise stated. When described on 5/25/79 the soil was slightly moist below 2 feet but the moisture was estimated to be held at a tension of greater than 15 bars.)
A11--0 to 1 inch; grayish brown (2.5Y 5/2) loamy fine sand, very dark grayish brown (2.5Y 3/2) moist; weak medium platy structure; soft, very friable; many very fine roots; many very fine interstitial pores; slightly effervescent (1 percent calcium carbonate) broken shell fragments less than 0.5mm; EC 0.6mmhos; SAR 1; slightly acid (pH 6.4); abrupt smooth boundary. (1 to 2 inches thick)
A12--1 to 24 inches; light gray (2.5Y 7/2) loamy fine sand, dark grayish brown (2.5 4/2) moist; single grained; loose; many very fine roots; many very fine interstitial pores; strongly effervescent (2 percent calcium carbonate) broken shell fragments less than 0.5mm; disseminated lime; EC 0.25mmhos; SAR 4; mildly alkaline (pH 7.4); abrupt smooth boundary. (12 to 30 inches thick)
C--24 to 60 inches; light gray (5Y 7/1) loamy fine sand, olive gray (5Y 5/2) moist; massive; soft, very friable, few very fine roots; many very fine interstitial pores; strongly effervescent (3 percent calcium carbonate) broken shell fragments less than 0.5mm; disseminated lime; EC 0.6mmhos; SAR 29; very strongly alkaline (pH 9.5).
TYPE LOCATION: Kings County, California; about 7.2 miles south of Utica Avenue and 3.5 miles east of Interstate 5; about 100 feet south of a dirt road; 1,520 feet east and 1,720 feet south of the northwest corner of sec. 19, T.24S., R.21E, MDB&M.
RANGE IN CHARACTERISTICS: The mean annual soil temperature ranges from 66 degrees to 67 degrees F. and the soil temperature is always above 47 degrees F. The soil is typically loamy fine sand but may be loamy sand or sand. The soil between depths of 12 and 35 inches is dry in all parts from March through December 1 and is not moist in some or all parts for as long as 75 consecutive days. The soil is more than 60 inches deep. Organic matter is less than 0.5 percent. The soil is effervescent throughout, with calcium carbonate ranging from 1 to 5 percent. The soil is effervescent throughout, with calcium carbonate ranging from 1 to 5 percent. There are a few shell fragments throughout the soil profile. The A horizon has dry color of 2.5Y 5/2, 7/2 or 7/1 and moist color of 2.5Y 3/2, 4/2 or 5/2. It is slightly acid to strongly alkaline.
The C horizon has dry color of 5Y 7/1 or 2.5YR 7/1 and moist color of 5Y 5/2 or 2.5Y 5/2. SAR ranges from 13 to 60. This horizon is moderately alkaline to very strongly alkaline.
COMPETING SERIES: These are the Kermit series in the same family and the Cajon series. Kermit soils are noneffervescent throughout and are moist in the control section during the summer. Cajon soils have mixed mineralogy.
GEOGRAPHIC SETTING: Sandridge soils occur on basin rims. Slopes are 0 to 3 percent. The slopes formed in wind-blown deposits derived dominantly from lake beach sediments composed of acid igneous and sedimentary rock. Elevations are 195 to 220 feet. The climate is arid and has hot, dry summers and mild, somewhat moist winters. The average annual precipitation is 6 inches. Mean January temperature is 47 degrees F.; mean July temperature is 85 degrees F.; mean annual temperature is 65 degrees F. Frost-free season is 255 to 270 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Boggs, Rambla and Westcamp soils. Boggs soils have a salic horizon and coarse-loamy particle-size control section. Rambla soils have a sandy over clayey particle-size control section and an aquic soil moisture. Westcamp soils have an aquic soil moisture regime and a fine-silty particle-size control section.
DRAINAGE AND PERMEABILITY: Somewhat excessively drained; very slow runoff; moderately rapid permeability.
USE AND VEGETATION: This soil is used for irrigated cropland such as cotton, barley, alfalfa or grapes, and used as wildlife land. Natural vegetation is grasses and forbs.
DISTRIBUTION AND EXTENT: San Joaquin Valley, California. The series is of small extent.
