Coy soil series
A representative soil profile of Coy clay loam, 1 to 3 percent slopes. The thick, dark-colored surface layer is indicative of high natural fertility. (Soil Survey of Duval County, Texas; by John L. Sackett III, Natural Resources Conservation Service)
The Coy series consists of very deep, well drained, slowly permeable soils that developed in calcareous clayey alluvium derived from mudstone. These soils are on nearly level to moderately sloping terrace remnants and broad flats associated with drainage ways. Slope ranges from 0 to 5 percent. Mean annual precipitation is about 737 mm (29 in) and the mean annual air temperature is about 21.7 degrees C (71 degrees F).
TAXONOMIC CLASS: Fine, smectitic, hyperthermic Pachic Vertic Argiustolls
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.
Mean annual soil temperature: 22 to 23 degrees C (72 to 74 degrees F)
Thickness of Mollic epipedon: 51 to 114 cm (20 to 45 in)
Thickness of Argillic horizon: 51 to 127 cm (20 to 50 in)
Vertic properties: When dry, the soil has cracks up to 5 cm (2 in) wide at the surface that extend to depths of more than 100 cm (40 in).
Depth to Calcic horizon: 89 to 152 cm (35 to 60 in)
USE AND VEGETATION: Mainly used for crop production with some areas used for livestock grazing and wildlife habitat. 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, huisache, and mesquite.
DISTRIBUTION AND EXTENT: Northern and Central Rio Grande Plain of Texas (MLRA 83A, 83C); Land Resource Region I. The series is of moderate extent. The Coy soils were formerly included with the Monteola series.
