This moderately well <br /> drained, nearly level soil is on low terraces. It is moderately deep to a hardpan. It <br /> formed in alluvium derived from mixed rock sources (USDA, p.87). <br /> Typically, the surface layer is grayish brown fine sandy loam about 11 inches thick. <br /> The upper part of the subsoil is grayish brown and light brownish gray fine sandy <br /> loam about 13 inches thick. The next part is a light gray, indurated hardpan, which <br /> extends to a depth of 35 inches. The lower part is a light gray, weakly cemented to <br /> strongly cemented hardpan, which extends to a depth of 54 inches. The underlying <br /> material to a depth of 74 inches is variegated light gray and white sandy loam. In <br /> some areas the surface layer is loam or clay loam (USDA, p.87). <br /> Permeability is moderate in the Manteca soil. Available water capacity is low... <br /> Runoff is slow, and the hazard of water erosion is slight... The hazard of soil blowing <br /> is moderate (USDA, p.87). <br /> 266—Veritas fine sandy loam,0 to 2 percent slopes. This moderately well drained, <br /> nearly level soil is on low fan terraces.
