Leoncita soil series
Profile of Leoncita fine sandy loam, 1 to 3 percent slopes. Leoncita is a loamy soil that has no physical or chemical restrictions within 40 inches of the surface and is well suited to rangeland and pastureland. It is found on ancient terraces near the Frio and Nueces Rivers. (Soil Survey of McMullen County, Texas; by Clark K. Harshbarger, Jon Wiedenfeld, and Gary Harris, Natural Resources Conservation Service)
The Leoncita series consists of very deep, well drained, moderately permeable soils that formed in calcareous loamy alluvium of Pleistocene age. These nearly level to moderately sloping soils are on risers and treads of remnant paleoterraces. Slopes range from about 0 to 5 percent. Mean annual precipitation is about 635 mm (25 in) and mean annual air temperature is about 22 degrees C (72 degrees F).
TAXONOMIC CLASS: Fine-loamy, mixed, superactive, hyperthermic Aridic Calciustolls
Soil Moisture: An aridic ustic moisture regime. The soil moisture control section is moist in some or all parts for less than 90 consecutive days in normal years. June to August and December to February are the driest months, while September to November and March to May are the wettest months.
Mean annual soil temperature: 21 to 23 degrees C (70 to 73 degrees F)
Particle-size control section (weighted average): 18 to 25 percent (carbonate clay-free basis)
Depth to secondary calcium carbonate: 28 to 203 cm (11 to 80 in)
Depth to calcic horizon: 28 to 160 cm (11 to 63 in)
Particle-size control section (weighted average)
Clay content: 18 to 30 percent
USE AND VEGETATION: Used mostly for livestock grazing and wildlife habitat. Some areas are crop production, mostly for grain sorghum. Present vegetation includes pink pappusgrass, lovegrass tridens, fall witchgrass, hooded windmillgrass, and plains bristlegrass. Woody vegetation includes mesquite, catclaw, spiny hackberry, and blackbrush, and guallijo.
DISTRIBUTION AND EXTENT: Western and Central Rio Grande Plain, Texas; LRR I; MLRA 83B and 83C; The series is of moderate extent. The series was formerly included in the Hidalgo series. The Hidalgo series parent material is associated with deltas and coastal terraces. The series was separated based on the source and age of the alluvium. Leoncita soils formed from inland calcareous loamy alluvium of Pleistocene age associated with remnant paleoterraces.
