ATTAC[A7ENT 2
32-Munn clay loam, 0 to 4 percent slopes. This
deep, Weary level to gently sloping, well drained, soil is
on terraces end lane. It formed in mixed clayey alluvium.
Elevation ranges from about 5,300 to 6,400 feet. Aver-
eqe annual precipMation ie about 14 to 17 inches, aver-
epe annual air temperature is about 47 degrees F, end
average boat-free period is about 135 days.
Included with thle soil In mapping are smell areas of
Englewood stay bem; Haolustolls, loamy, Weary level;
and Heldt clay. loam. They each have 0 to 4. percent
slopes. .: ,
Typicaly, the surface layer is grayish brown clay loam
.about 8 inches thick. The subsoil is grayish brown clay
loam, clay, and silty clay to a depth o1 about 40 Inches.
The substratum Is Tight brownish grey sandy loam to a
depth of about 55 inches and light olive brown silty clay
to a depth of 60 Inches. -
Permeability le Blow, and available water capacity la
high. SuAace runoff le slow, end the hazard o1 erosion Is
slight.
This soil {s used mainy for nonirrigated cropland and
grazing. A few email areas are used for irrigated crop-
land. Wheat and forage sorghums are the main crops on
:nonirrigated Cropland. The eBUmated yield for wheat is
about 20 bushels per acre. Alfalfa and corn are the main
crops on Irtlgeted aoplarid. -
On nonirrigated cropland, management pracikes, such
es stubble mulch tillage and Incorporating crop residue In
end on the suAace are needed to improve water Inflltre-
tlon. Tillage pens form easiy B this loll Is Ulied when
wet. Chiseling Or subsolling breaks up tillage pane and
Improves water IrHiltration. Tillage operations need to be
kept to a minimum. Terracing Is also beneflclal for reduc-
ing runoff and conserving mol8ture.
Management Concerns on Irrigated cropland are
melny proper use of Irtigaflon water, slow permeability,
and maintenance of fertility. Incorporating crop residue in
the surtace Increases infiltration and improves soil filth.
Applications of manure and commercial fertilizers that
contain nitrogen end phosphorus are needed to maintain
soli productivity. .. ...._.

Rangeland vegetation Is mainly western wheatgrasa
blue grams, green needlegress, end fourwing saltbush
Following prolonged overgrazing, native bluegrassa;
annual grasses, end weeds Increase. Contour furrowing
or pitting aids in the recovery of depleted vegetation o:
this soil by reducing runoff and Increasing water infiltra
lion. Areas that have dense stands of prlcklypear o
rabbitbrush can be managed by chemical control o
these species.
This soil is well suited to windbreaks and environmen
tai plantings. Summer fallow, a year prior to planting
supplemental Irrigation during planting and early stage
of growth; end continued Cultivation for weed control arc
needed to insure the establishment and survival of plan)
ings. Weil suited trees that survive best are Aocky Moun
~, fain uni er, eastern redceder, onderosa
1 P p pine, Siberiar
elm, Russian-olive, and hackberry. The best suites
shrubs are skunkbush sumac, American plum, lilac, errs
Siberian peeahrub.
Limiting soA features for homesites entl other urbar
uses are slow permeability and high shrink-swell poton
tial. Special designs for buildings and roads are needec
to offset these limitations. Special.sewage systems, suer
_atl,enclosed to kn s that can be umped ouf periodically
are needed. Septic tank absorp on fields will not turio
lion properly because of the slow permeability.
This soil is in capability subclass Ills, nonirrigated arc
ile, irrigated.
THIS SOIL IS-IN HEL CLASS 3 FOR WIND AND
CLASS 3 FOR WATER. THERE ARE NO HYDRIC
COMPONENTS IN THIS SOIL UNIT.
