Slopes <br /> are 9 to 15 percent. This component is on escarpments, terrace breaks. The <br /> parent material consists of gravelly alluvium. Depth to a root restrictive layer is <br /> greater than 60 inches. The natural drainage class is excessively drained. Water <br /> movement in the most restrictive layer is high. Available water to a depth of 60 <br /> inches(or restricted depth) is very low. Shrink-swell potential is low. This soil is <br /> not flooded. It is not ponded. There is no zone of water saturation within a depth <br /> of 72 inches. Organic matter content in the surface horizon is about 1 percent. <br /> Nonirrigated land capability classification is 7s. This soil does not meet hydric <br /> criteria. The calcium carbonate equivalent within 40 inches, typically, does not <br /> exceed 3 percent. There are no saline horizons within 30 inches of the soil <br /> surface. <br /> Component: Columbo(10%) <br /> Generated brief soil descriptions are created for major soil components.
