The Raisin series consists of very deep, well drained soils that formed in loamy alluvium of Quaternary age. These nearly level to gently sloping soils are on high stream terraces. Slope ranges from 1 to 5 percent. Mean annual precipitation is about 965 mm (38 in) and the mean annual air temperature is about 21 degrees C (70 degrees F).

 

TAXONOMIC CLASS: Fine-loamy, mixed, superactive, hyperthermic Typic Haplustalfs

 

Solum thickness is more than 80 inches.

Soil Moisture: An ustic soil moisture regime. The soil moisture control section, 4 to 12 inches, is dry in some or all parts for more than 90 but less than 180 cumulative days in normal years. July through September, December, and March are the driest months.

Mean annual soil temperature: 22 to 23.5 degrees C (72 to 74 degrees F)

Depth to argillic horizon: 10 to 19 cm (4 to 19 in).

Particle-size control section (weighted average)

Clay content: 27 to 35 percent

CEC to clay: 0.6 to 1.5

 

USE AND VEGETATION: Used mainly as rangeland and wildlife habitat. The vegetation is live oak, post oak, bluestems, gramas, and threeawns. Mesquite and huisache have encroached in some areas. The ecological site for phases with a sandy surface layer is loamy sand 25 to 35 inch PZ (R083AY396TX ) and Sandy Loam 25 to 35 inch PZ (R083AY407TX) for loamy surface phases.

 

DISTRIBUTION AND EXTENT: South Central Texas; MLRA 83A; LRR I; moderate extent

 

These soils were formerly included in the Delfina series. The Delfina series has aquic conditions and the series province is confined to MLRA 83D in the lower Rio Grande valley. The redoximorphic features in the argillic horizon are not contemporary. These soils are in association with other soils that have borderline siliceous/mixed mineralogy.
