Clareville soil series
Profile of Clareville sandy clay loam in an area of Czar-Clareville complex, 0 to 2 percent slopes, rarely flooded. The rich dark surface of this profile indicates an accumulation of organic matter and is naturally fertile. (Soil Survey of McMullen County, Texas; by Clark K. Harshbarger, Jon Wiedenfeld, and Gary Harris, Natural Resources Conservation Service)
The Clareville series consists of very deep, well drained soils that formed in loamy alluvial sediments of Holocene age. These nearly level to very gently sloping soils are on base slope on draws and drainageways. Slope ranges from 0 to 5 percent but mainly less that 2 percent. Mean annual precipitation is about 711 mm (28 in) and mean annual air temperature is about 22 degrees C (72 degrees F)
TAXONOMIC CLASS: Fine, smectitic, hyperthermic Pachic Argiustolls
Solum thickness ranges from 150 to 203 (60 to 80 in). The mollic epipedon is 50 to 127 cm (20 to 50 in) thick.
Soil Moisture: A typic-ustic moisture regime. The soil moisture control section is dry in some or all parts for more than 90 days but less than 180 cumulative days in normal years. June through August and December through February are the driest months. These soils are intermittently moist in September through November and March through May. Mean annual soil temperature: 22 to 24 (72 to 75 degrees F).
Depth to secondary calcium carbonate: 61 to 91 cm (24 to 36 in)
Particle-size control section (weighted average)
Clay content: 35 to 45 percent
USE AND VEGETATION: Used mainly as cropland but some areas are in rangeland. Cultivated crops are cotton, grain sorghum, and corn. Native grasses include Arizona cottontop, little bluestem, sideoats grama, curlymesquite, and Texas bristlegrass. Woody invaders are whitebrush, spiny hackberry, and mesquite.
DISTRIBUTION AND EXTENT: Northern and Central Rio Grande Plain and Gulf Coast Prairies, Texas; LRR I; MLRA 83A, 83C. The series is moderately extensive.
