6-Breeaer sandy loam, 4 to 8 percent slopes. This
deep, well drained soil loaned in alluvium and residuum
weathered Irom erkoslc sandstone. It is on gently rolling
uplands and aide elopes. Elevation ranges from about
5,300 to about 8,400 lest. Average annual precipitation
ranges Irom about 14 to 17 Inches, average annual air
lempertture le about 47 degrees F, and average frost-
Iroo period la about 135 days.
Included with this soil in mapping are smell areas of
Breeaer Bandy loam, 0 to 4 percent elopes. Also Included
are Ascalon bandy loam and Truckton sandy loam that
have 4 to A percent elopes.
Typically, the surface layer Is greyish brown sandy
loam about 7 Inches thick. The subsoil Is brown sandy
clay loom to a depth of about 20 Inches and pall brown
sandy loam t0 a depth of about 2g Inches. The substre•
tum Is very pale brown loamy send to a depth of 60
Inches.
Permeeblllry and available water capacity are rnoder-
ato, SurleCe runoff le medium, and the hazard of erosion
la moderate. A few gullies are In some places.
Less then hell of this soil Is used for nonlrrigated
cropland. Whset Is the main crop. The estimated yield
for wheat la about 17 bushels per acre. Moat of the
remaining aaeegtl Is used for grazing. Some areas of
this loll are used for homesiles and other urban pur•
posse.
Consorving moisture end prolecting the soil Irom aro•
abn ore the main concerns of management on nonirri•
gated cropland. Summer tallow Is necessary because of
the absence of adequate precipitation. Stubble mulch
tillage and Incorporating crop residue in and on the sur•
lace are necessary to protect soil Irom erosion, improve
soil filth, end conserve moisture. Chiseling breaks up
tillage pansand Improves watgr,infiltration in the subsoil.
SUipcroDPing el right angles to the prevailing wind is also
,ellactivu In prolecting the soil Irom blowing (figs. 1 l0 4).
Tillage operatbns need to be kept to a minimum.
Rsngeland 'vegetation is mainly blue grams. prairie
aandreed, neadleandthread, little bluestem, and sidooals
grsma. When range condition deteriorates because of
overgrazing or other uses, grasses, such as blue grams
and natNe bluegrassesfessdand annuals 9epeaco ~he o

grasses II the range becomes seriously deteriorated.
Seeding the range is recommended to revogelate do•
plated erase In order to protect the soil Irom wind and
water erosion. Native grasses, such as big bluestem,
little bluestem, aldeoats grams, end prairie sendreed, are
rocommended for range seeding. Tame grasses. such as
cr:-ted wheatgraes, Russian wildrye, pubescent whoat•
grass. or Inlermedlete wheetgress, may also be used.

Thla Boll Is generally suited to windbreaks and onviron•
mental plantings. Wind erosion Is the main limitation to
the establishment of trees and shrubs. This hazard can
be overcome by cultivating only in the tree row and
leaving a strip of vegetative cover between tho tows.
Supplemental Irrigation is generally necessary at the time
of planting and during dry periods. Well suited trees That
survNe best aro Rocky Mountain Juniper, eastern redce•
der, ponderosa pine, Siberian elm, Russian•olive, and
hackberry. The best suited shrubs are skunkbush sumac,
American plum, end Hansen rose.
This soil is well suited for homesiles and other urban
uses and has only minor limitations that can bo easily
overcome. Whero this soil le used for a sewage lagoon
system, special sealing methods are needed to over
Come the excessive seepage condition.
