<br />SOILS INFORMATION
<br />Stroupe Series
<br />The Stroupe series wnaieta of moderately deep, well-
<br />drained soils. These soils formed on mesas and foot-
<br />hills 1n clayey residuum weathered from sandstone.
<br />They are underlain by sandstone at a depth of 20 to
<br />40 inches. The slope ie 9 to 26 percent, and elevation ie
<br />6,800 to 8,600 feet. The average annual precipitation ie
<br />18 inches. The average annual temperature ie 47° F,
<br />and the frost-free eetlllon le 116 to 146 days. The native
<br />vegetation le mainly foothill graeeee and shrubs.
<br />In s representative profile the surface Isyer is brown
<br />extremely stony loam about 4 Inches thick. The upper
<br />part of the subsoil ie brown very stony loam about
<br />6 inches thick, and the lower part ie reddish-brown
<br />very stony clay loam about 16 inches thick. Sandstone
<br />bedrock fa at a depth of about 26 inches.
<br />Permeability ie slow, and the available water ca-
<br />pacity is low. The surface layer and eubeoil are neutral,
<br />and the underlying material ie neutral or mildly alka-
<br />line. The root zone extends to a depth of 20 to 40
<br />inches. These soils are used almost exclusively for
<br />grazing.

<br />The B2t horizon ranbes from stony clay to very stony clay
<br />loam. In pplaces there s a weakly developed Ilme zone at e
<br />depth of 20 Inches or more. In [hla zone, thin Ilma coating~

<br />StE--Slroupe extremely eiony loam, 9 l0 25 pereenl
<br />slopes. This soil is in the western part of the survey
<br />area In long areas that cover as much ae 1,800 acres.
<br />Flaggy sandstone fragments cover about 10 percent of
<br />the soil surface.
<br />Included with this: soil in mapping are areas of
<br />sandstone Rock outcrop; these make up about 16
<br />percent of the acreage.
<br />Runoff is medium, and the hazard of erosion is slight.
<br />This soil is suited to grazing. It hsa potential for
<br />wildlife use if the habitat can be improved. Herbage
<br />production is limited by the low available moisture
<br />capacity. About one-third of the acreage is pinyon-
<br />juniper woodland, end the rest le grassland. The native
<br />vegetation ie mainly western wheatgrase, blue grams,
<br />aide-oats grams, yucca, cactus, mountainmahogany,
<br />pinyon pine, and juniper. Capability unit VIIe-8, non-
<br />irrigated ;Shallow Foothills range site.
