Custom Soil Resource Report <br /> Clay <br /> As a soil separate, the mineral soil particles less than 0.002 millimeter in <br /> diameter. As a soil textural class, soil material that is 40 percent or more clay, <br /> less than 45 percent sand, and less than 40 percent silt. <br /> Clay depletions <br /> See Redoximorphic features. <br /> Clay film <br /> A thin coating of oriented clay on the surface of a soil aggregate or lining pores <br /> or root channels. Synonyms: clay coating, clay skin. <br /> Clay spot(map symbol) <br /> A spot where the surface texture is silty clay or clay in areas where the surface <br /> layer of the soils in the surrounding map unit is sandy loam, loam, silt loam, or <br /> coarser. <br /> Claypan <br /> A dense, compact subsoil layer that contains much more clay than the overlying <br /> materials, from which it is separated by a sharply defined boundary. The layer <br /> restricts the downward movement of water through the soil. A claypan is <br /> commonly hard when dry and plastic and sticky when wet. <br /> Climax plant community <br /> The stabilized plant community on a particular site. The plant cover reproduces <br /> itself and does not change so long as the environment remains the same. <br /> Coarse textured soil <br /> Sand or loamy sand. <br /> Cobble (or cobblestone) <br /> A rounded or partly rounded fragment of rock 3 to 10 inches (7.6 to 25 <br /> centimeters) in diameter. <br /> Cobbly soil material <br /> Material that has 15 to 35 percent, by volume, rounded or partially rounded rock <br /> fragments 3 to 10 inches (7.6 to 25 centimeters) in diameter. Very cobbly soil <br /> material has 35 to 60 percent of these rock fragments, and extremely cobbly <br /> soil material has more than 60 percent. <br /> COLE (coefficient of linear extensibility) <br /> See Linear extensibility. <br /> Colluvium <br /> Unconsolidated, unsorted earth material being transported or deposited on side <br /> slopes and/or at the base of slopes by mass movement (e.g., direct <br /> gravitational action) and by local, unconcentrated runoff. <br /> 37 <br />
