SOIL SURVEY OF KAUFMAN COUNTY, TEXAS 71 and fragments or rolls like a wire. Field test at a depth of 24 inches gave a pH value of 6.0. Bs. 48 to 66 inches, gray slightly calcareous very plastic very compact blocky clay containing a few concretions of calcium carbonate and gypsum. The material is faintly less compact than in the overlying horizon. C. 66 to 80 inches+, yellowish-gray calcareous very compact clay, slightly mottled with yellow surrounding black centers (apparently iron oxide) and containing white concretions of calcium carbonate. As seen in other locations, the calcium carbonate concretions occur down to but not below a depth of about 10 feet. The Wilson profile is most characteristically developed in medium-heavy textures in smooth, nearly level or very gently sloping, slowly drained areas. It does not occur on sloping areas in textures lighter than clay loam. \ Sloping acid soils of the / prairies with surface soils ' that are lighter textured ( than clay loam have darkbrown surface soils and reddish-brown upper sub ' soil layers mottled with\ red. Such soils are mem Ci bers of the Crockett series. The red color apparently is an expression of less \ o. hydration of the iron com \ \ pounds than occurs in the /..

These sandy margins cross the strike of the geological formations and accordingly represent different developments from the same parent material. The flattest and most slowly drained areas of Wilson very fine sandy loam, especially those of the mound phase, are gradations toward the Lufkin soils and have more or less of a gray layer at the base of the A horizon. The only apparent soil development in the blackland soils, which are typified by Houston Black clay, is some leaching of carbonates out of the surface horizons and the accumulation of organic matter. These soils are underlain by a slight zone of carbonate accumulation or at least by a zone of translocated carbonates. No texture profile and no true B horizon are developed. The topography and profile
