<br />3lf•-Peyton-Pring complex, 8 to 25 percent slopee.
<br />These deep, moderately sloping to moderately steep,
<br />well drained soils are on upland hills and ridges. Eleva-
<br />tion ranges from about 6,400 to 7,300 feet. Average
<br />annual precipitetlon ranges from about 17 to 19 inches,
<br />and average annual air temperature is about 43 degrees
<br />F. The Peyton soil makes up about 50 percent of the
<br />unit end the Prinp soil about 35 percent. The Peyton soil
<br />le along tlrelnepeways end the lower side elopes. Tho

<br />brown ooerae sandy loam and loamy coarse send to a
<br />depth of 80 Inches
<br />Permeeblllty le rapid, and available water capacity is
<br />moderate. Surface runoff is medium, and the hazard of
<br />erosion is moderate. Gullies have developed along some
<br />of the drelnageweys.
<br />Moat of the soils In this unit are used for grazing. A
<br />few arses are used for ttomesitea. These soils have poor
<br />poterttlal for cropland because of steep slopes.
<br />Rangeland vegetation on the Peyton soils is meinty
<br />mountain mutely, western wheatgress, sand and little
<br />bluestem, needlegresaes, prairie sandreed, and prairie
<br />junegrsas. The predominant grasses on the Pring soil are
<br />Arizona fescue, mountain matey, needlegress, blue
<br />preme, end Perry oetpreee. When range condition ctote•

<br />Seeding the range Is recommended to revegetate de-
<br />pleted areas In order to protect the soil from wind and
<br />water erosion. Native grasses, such es western wheat-
<br />grese, mountain brome, and Arizona fescue, are recom-
<br />mended for range seeding.
<br />These lolls are generally salted to windbreaks and•
<br />envlronmentel plantings. Wind erosion is the mein limita-
<br />tion to the establishment of trees and shrubs. This
<br />hazard can be overcome by cultivating only in the tree
<br />row and leaving a strip of vegetative cover between the
<br />rows. Supplemental Irrigation is generally needed at the
<br />time of planting end during dry periods. Well suited trees
<br />that survive best are Rocky Mountain juniper, eastern
<br />redcedar, ponderosa pine, Siberian elm, Russian-olive,
<br />and heckberry. The best suited shrubs are skunkbush
<br />sumac, American plum, and Hansen rose.
<br />Where these soils are used for homesites and other
<br />urban uses, the main limiting soil properly is steep
<br />slopee. These soils need special site or building designs
<br />because of the slope.
<br />This complex is in capability subclass Vle, nonirrigated.
