CU5fer County Area, Colorado • <br />29 <br />^~-~ - <br />maintain and improve the plant cover and control <br />erosion. Cross fencing, livestock water developments, <br />salting, and erosion control structures help to prevent <br />range deterioration and promote the production of the <br />more desirable plants. Seeding on this soil is limited to <br />broadcasting because of stoniness. Suitable plants for <br />seeding are intermediate, pubescent, western, and <br />Nordan crested wheatgrasses; Russian wildrye; and <br />Arizona fescue. <br />This soil is poorly suited to use as homesites. The <br />major limiting features are slope and large amounts of <br />rock fragments. <br />This soil is in capability subclass Vlle, nonirrigated. <br />34-Sllvercllff very cobbly sandy loam, 30 to 50 <br />percent slopes. This is a deep, well drained soil on <br />terrace edges. It termed in colluvium and alluvium. <br />Elevation is 8,400 to 9,200 feet. The average annual <br />precipitation is 16 to 18 inches, the average annual <br />temperature is 40 to 44 degrees F, and the Trost-free <br />season is 55 to 75 days. <br />Typically, the surface layer is dark grayish brown very <br />cobbly sandy loam 8 inches thick. The subsoil is brown <br />very cobbly sandy loam 12 inches thick. The substratum <br />is pinkish white very cobbly sandy loam in the upper 30 <br />inches and light brown very gravelly loamy sand to a <br />depth of 60 inches or more. <br />The soil is mildly alkaline to a depth of 20 inches and <br />moderately alkaline and calcareous below that depth. <br />Included with this soil in mapping are areas of <br />sandstone Rock outcrop on the steeper parts of the <br />Landscape. They make up about 5 percent of the map <br />unit. <br />Permeability of this Silvercliff soil is moderately rapid, <br />and the available water capacity is low. The effective <br />rooting depth is 60 inches or mare. Surface runoff is <br />medium, and the hazard of erosion is high. <br />Most areas are used for livestock grazing, woodland, <br />and wildlife habitat. <br />The potential native vegetation is mainly pinyon and <br />Rocky Mountain juniper. The understory is dominantly <br />blue grama, mountain muhly, muttongrass, Arizona <br />fescue, Indian ricegrass, and mountainmahogany. As the <br />understory deteriorates, three-awn, blue drama, <br />rabbitbrush, snakeweed, and pricklypear increase. If <br />properly managed for woodland grazing, these areas <br />retain their maximum productivity. <br /> <br />Figure B.-Irrigation of haylend by flooding. Tne soil Is Silvorclill gravelly sandy loam, 1 l0 4 percent slopes. <br />
