5.3.2 GEOLOGY (Continued) COMPETING SERIES: These are the Fiat and Mayes series in the same family and the Bonham, Edna, leanerette, Lake Charles, Mabank, Morey, Muldrow, and Wilson series. Fiat soils have a 20 to 40 inch cola over limestone. Mayes soils have A horizons thicker than B inches and are of cooler soil temperatures. Bonham soils are not dominated by gray colors in the Bt horizon and have mixed mineralogy. Edna, Mabank, and Wilson soils have ochric epipedons. leanerette and Morey soils are of a fine -silty textural family. Lake Charles soils lack Bt horizons and have intersecting slickensides. Muldrow soils have mixed mineralogy and lack vertic properties. GEOGRAPHIC SETTING: Bernard soils occur on nearly level coastal prairies. Slopes are mainly less than 1 percent but areas bordering narrow natural drains range to 5 percent. Bernard soils formed in fine textured, unconsolidated sediments of Pleistocene age (Beaumont formation). The mean annual temperature in the area of the soils distribution is about 68 to 70 degrees F.; mean annual precipitation, which is about evenly distributed throughout the year, is 40 to 50 inches, and Thornthwaite annual P-E indices are 54 to 75. GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Edna and Lake Charles series and the Addicks, Clodine, Katy; and Midland series. Addicks and Clodine soils have coarse -loamy control sections. Katy soils have thick light colored loamy A horizons and mottled red, yellow, and gray Bt horizons. Midland soils lack mollic epipedons and are poorly drained. DRAINAGE AND PERMEABILITY: Somewhat poorly drained; very slow runoff; very slow to slow internal drainage; very slow permeability. The soil is saturated within 2 feet of the surface during the winter and early spring. USE AND VEGETATION: Mainly used for growing corn, cotton, grain sorghums, and rice. A few areas are in improved pastures of bermudagrass, bahiagrass, and dallisgrass. Native vegetation is tall prairie grasses, mainly andropogons and paspalums, and a few widely spaced elm and huisache trees. DISTRIBUTION AND EXTENT: Coastal Prairie of Texas and Louisiana. The series is extensive, the estimated area is about 500,000 acres. MLRA OFFICE RESPONSIBLE: Temple, Texas SERIES ESTABLISHED: Fort Bend County, Texas; 1952. REMARKS: Diagnostic horizons recognized in this pedon are: Mollic epipedon - 0 to 35 inches Argillic horizon -6 to 50 inches, high shrink -swell, low chroma colors due to wetness ADDITIONAL DATA: S55TX-79-91, Published in SSIR-30 and in Ft. Bend County Soil Survey Report. National Cooperative Soil Survey U.S.A. Urban land is land mostly covered by streets, parking lots, buildings, and other structures of urban areas.
