ATTACHMENT 2 •
34-Peyton sandy loam, 4 to B percent slopes. Thla
deep, genty sloping to moderately sloping, well drained
soil la on upland alluvial fans and valley aide slopes (fig.
t4). It formed In erkosic alluvium and residuum. Elevatbn
ranges from about 8,400 to 7,300 feet Average annual
predpttetbn rerlpea from about 17 to tg Inches, average
gfvwal etr temperature la about 43 degrees F, and aver•
ape froat•hee perbd le about 120 days.
Included with this Boll In mapping are small areas of
Bruasett tam, Holdemeas loam, and Elbeth sandy tam
that have 4 to 8 percent elopes.
Typlcaly, the surface layer Is grayish brown sandy
loam and dark grayish brown,aendy clay loam about 7
Inches thick. The aubsal to a depth of about 32 Inches
b dark greyish brown, greyish brown, and light brownish
gray Bendy clay tem. The substratum Is tight brownish
gray and white coarse sandy loam and loamy coarse
sand to a depth of 80 Inches.
PermeabUfty Is moderate, end avellable water capacity
b moderate to hfph. Surface runofl is medium, and the
hazard of erosbn Is moderate. In a few areas, shallow
gullies and rills ere common.
Moat of this soil b used }or grezlnp. A law areas ere
used for nortirrlgeted cropland, and wheat la the main
sop. Tha estimated yield for wheat Is spout 20 bushels
per sae, and K Is 27 bushels per sae for oats. The
ctwice of trope Is limited by the short prowtnp season.
This sal Ia well suted to windbreaks end environmental
plMtlnpe and for most engineering uses.
Rangeland vepetaUon fs melny prairie sandreed,
mountain muhty, sand blueetem, prairie Junegrass, little
bkrestem, end blue grams. When range conditbn d~te-
rlorates because of overgrazing or other uses, greases,
such es blue prams end native bluegraasea, and forts,
such as hairy poldaeter, increase.
Seeding the range is recommended to revegetate de•
plated areas IrI order to protect the soil from wind and
water erosion. Native grasses are desirable for range
seeding, but tame apeGea, such ae Nordan created
wtteetgrass, Russlerl wlldrye, pubescent wheatgrass, and
intennedlat¢ wheatgress, may also be used.
The main concerns management on nonurigated
cropland are conserving moisture and protecting fhe soil
from wind and water erosion. Stubble mulch tillage and
IncorporeUng crop residue in end on the surface are
necessary to protect the soil from erosion, improve soil
Ulth, and conserve moisture. Chiseling or subsoiling
breaks up tillage pane and Improves water infilVation in
the subsoil. Planting trope in alternate strips at right
angles to the gravelling wind ie also effective in protect-
ing the soil from blowing. Tillage operations need to be
kept to a minimum.
This soil Is generally suited to windbreaks and envvon-
mental plantings. Wind erosion fa the main limitation to
the establlahment of trees and shrubs. This hazard can
be overcome by cultivating only In the tree row and
leaving a strip o1 vegeteWe cover between the rows.
Supplemental InipeUon is generally needed. at the time of
Planting end during dry periods. Well suited trees that
survive beat are Rocky Mountain Juniper, eastern redce-
der, ponderosa pine, Siberian elm, Russian•olive, and
hackbeny. The best euked shrubs ere akunkbush sumac,
American plum, end Henson rose.
This soil la well suited to the construction of homesites
and other urban developments end has only minor limita-
tbns that can be easily modflied Where this soil is used
for a sewage lagoon system, special sealing methods
ere needed to Overcome the excessHe seepage condi-
tion. '
This sal is in Cepabllily subclass IVs, nonirrigeted.
THIS SOIL IS IN HEL CLASS 1 FOR WIND,AND•
CLASS 3 FOR WATER. THERE ARE NO HYDRIC
COMPONENTS IDI TFIIS SOIL.
