It formed <br />In residuum derived dominantly from interbedded sandstone and shale. <br />typically, the surface layer is reddish brown loam 5 inches thick. <br />The upper part of the subsoil is reddish brown loam 7 inches thick. <br />fhe lower part is pinkish white gravelly loam 11 inches thick. Hard <br />sandstone ~s at 23 inches. In some areas the surface layer is fine <br />:sandy loam or sandy loam. <br />Permeability of the Bowdish soil is moderate. Available water <br />r:.apacity is low. Effective rooting depth is 20 to 40 inches. Runoff <br />is moderate, and the hazard of water erosion is high. <br />The Progresso soil is moderately deep and well drained. It formed <br />in alluvium derived dominantly from sandstone.
