Map Unit Description (Brief, Generated) <br />Lincoln County, Colorado <br />[Minor map unit components are excluded from this report] <br />Map unit: 130 -Fort loam, 3 to 5 percent slopes <br />Component: Fort (85%) <br />The Forl component makes up 85 percent of the map unit. Slopes are 3 to 5 percent. The parent material <br />consists of alluvium and/or eolian deposits. Depth to a root restrictive layer is greater than 60 inches. The <br />natural drainage class is well drained. Water movement in the most restrictive layer is moderately high. <br />Available water to a depth of 60 inches is high. Shrink-swell potential is moderate. This soil is not flooded. It is <br />not ponded. There is no zone of water saturation within a depth of 72 inches. Organic matter content in the <br />surface horizon is about 2 percent. This component is in the R069XY006C0 Loamy (formerly Loamy Plains) <br />ecological site. Nonirrigated land capability classification is 4e. This soil does not meet hydric criteria. The <br />calcium carbonate equivalent within 40 inches, typically, does not exceed 10 percent. The soil has a slightly <br />sodic horizon within 30 inches of the soil surface. <br />Map unit: 153 -Midway-Razor clay loams, 5 to 15 percent slopes <br />Component: Midway (55%) <br />The Midway component makes up 55 percent of the map unit. Slopes are 5 to 15 percent. The parent material <br />consists of residuum weathered from clayey shale. Depth to a root restrictive layer, bedrock, paralithic, is 6 to <br />20 inches. The natural drainage class is well drained. Water movement in the most restrictive layer is low. <br />Available water to a depth of 60 inches is very low. Shrink-swell potential is moderate. This soil is not Flooded. It <br />is not ponded. There is no zone of water saturation within a depth of 72 inches. Organic matter content in the <br />surface horizon is about ~ percent. This component is in the R069XY046C0 Shaly Plains ecological site. <br />Nonirrigated land capability classification is 6e. This soil does not meet hydric criteria. The calcium carbonate <br />equivalent within 40 inches, typically, does not exceed 10 percent. The soil has a slightly saline horizon within <br />30 inches of the soil surface. The soil has a slightly sodic horizon within 30 inches of the soil surface. <br />Component: Razor (30%) <br />The Razor component makes up 30 percent of the map unit. Slopes are 5 to 15 percent. The parent material <br />consists of alluvium and/or residuum. Depth to a root restrictive layer, bedrock, paralithic, is 20 to 40 inches. <br />The natural drainage class is well drained. Water movement in the most restrictive layer is low. Available water <br />to a depth of 60 inches is low. Shrink-swell potential is high. This soil is not flooded. It is not ponded. There is <br />no zone of wafer saturation within a depth of 72 inches. Organic matter content in the surface horizon is about 2 <br />percent. This component is in the R069XY047C0 Alkaline Plains ecological site. Nonirrigated land capability <br />classification is 6e. This soil does not meet hydric criteria. The calcium carbonate equivalent within 40 inches, <br />typically, does not exceed 8 percent. The soil has a slightly saline horizon within 30 inches of the soil surface. <br />The soil has a moderately sodic horizon within 30 inches of the soil surface. <br />USA Natural Resources <br />~- Conservation Service Survey Area Version: 4 <br />Survey Area Version Date: 12/20/2006 <br />Page 1 <br />
