Slopes are 20 to 45 percent. This component is on mountainsides. The <br />parent material consists of residuum weathered from granite and/or residuum weathered from gneiss. Depth to a root restrictive layer, <br />bedrock, lithic, is 10 to 20 inches. The natural drainage class is well drained. Water movement in the most restrictive layer is moderately <br />high. Available water to a depth of 60 inches is very low. Shrink-swell potential is low. This soil is not flooded. It is not ponded. There is <br />no zone of water saturation within a depth of 72 inches. Organic matter content in the surface horizon is about 2 percent. Nonirrigated <br />land capability classification is 7e. This soil does not meet hydric criteria. The calcium carbonate equivalent within 40 inches, typically, <br />does not exceed 3 percent. <br />Map unit: 50 - Kim loam, cool, 3 to 8 percent slopes <br />Component: Kim, cool (95%) <br />The Kim, cool component makes up 95 percent of the map unit. Slopes are 3 to 8 percent. This component is on fans, fan terraces. The <br />parent material consists of alluvium and/or eolian deposits. Depth to a root restrictive layer is greater than 60 inches. The natural <br />drainage class is well drained. Water movement in the most restrictive layer is moderately high. Available water to a depth of 60 inches <br />is moderate. Shrink-swell potential is low. This soil is not flooded. It is not ponded. There is no zone of water saturation within a depth of <br />72 inches. Organic matter content in the surface horizon is about 1 percent. This component is in the R049BY202CO Loamy Foothill <br />ecological site. Nonirrigated land capability classification is 4c. Irrigated land capability classification is 4e. This soil does not meet hydric <br />criteria. The calcium carbonate equivalent within 40 inches, typically, does not exceed 8 percent. <br />Map unit: 64 - Louviers-Travessilla complex, 20 to 50 percent slopes <br />Component: Louviers (40%) <br />The Louviers component makes up 40 percent of the map unit.
