• EXHIBIT "I" <br />Soils Information <br />Casey J. Sheley, District Conservationist, stationed in the Walsenburg Field Office of the <br />NRCS provided the soils information. and recommended seed mixture and planting info. <br />The following soils where identified by Casey Sheley District Conservationist: <br />Soil Unit 91- Wily-Kim loam, 2 to 9 % slopes. This soil is mainly on uplands. Native <br />vegetation is primarily grass. The elevation is between 5500 to 6200 feet. The annual <br />average precipitation is 12 to 15 inches; the average air temperature is 50 to 54 degrees <br />F the average frost-free period is 135 to 165 days. <br />This unit is 55% Wiley loam and 40% Kim loam. The Wiley soil is on the gentler slopes and <br />in concave areas, and the Kim soil is on the steeper slopes and ridges. The components <br />of this unit are so intricately intermingled that it is not practical to map them separately. <br />Also in this unit is about 5% Schamber sandy loam on ridges. The Schamber soil is very <br />gravelly or very cobbly below the surface layer. In addition to the above there are small <br />isolated areas of Rock outcrop. <br />The Wiley soil is deep and well drained. It formed in silt and fine sand derived dominantly <br />from loess. Commonly, the surface layer is light brownish gray loam 4 inches thick. The <br />upper 10 inches of the subsoil is silty clay loam, and the lower 9 inches is silt loam. The <br />substratum to a depth of 60 inches or more is silt loam. The soil is mildly alkaline to a depth <br />• of 4 inches and moderately alkaline below that depth. <br />Permeability of Wiley soil is moderate. Available water capacity is high. Effective rooting <br />depth is 60 inches or more. Runoff is medium, and the hazard of water erosion is moderate <br />to high. <br />Permeability of the Kim soil is moderate. Available water capacity is high. Effective rooting <br />depth is 60 inches of more. Runoff is medium, and the hazard of water erosion is high to <br />very high. <br />This area with-in the 112c boundary is used for rangeland presently. The potential plant <br />community on this unit is mainly blue grama. Other grasses that characterize the unit are <br />western wheatgrass and sideoats grama. The average annual production of air-dry <br />vegetation is about 800 pounds per acre. If the condition of the range deteriorates, blue <br />grama, threeawn, and sand dropseed increase. <br />Soil Unit 77Schamber-Midway complex, 3 to 25% slopes. This soil unit exists on hills, <br />terrace edges, and side slopes. Native vegetation is mainly grass. Elevation is between <br />5500 to 6600 feet. Average annual air temperature is 49 to 54 degrees F, and the average <br />precipitation is 12 to 15 inches. The average frost-free period is 125 to 755 days annually. <br />The unit is about 65% Schamber sandy loam and about 20% Midway clay. The Schamber <br />soil is in the gently sloping areas and on hilRops, and the Midway soil is on the steeper side <br />slopes. The components of this unit are so intricately intermingled that it is nit practical to <br />map them separately. About 15% of this soil unit are Kim fine sandy loam on the foot <br />• slopes and in the drainways. <br />The Schamber soil is deep and excessively drained. It formed in alluvium. Normally, the <br />
