LOGAN COUNTY, COLORADO
ty, depth to sand and gravel, and slope are the principal
concerns in establishing tree and shrub plantings. Special
care consisting of summer fallow a year in advance of
phmting, plantings on the contour, continued cultivation
for weed control, and supplemental water is needed to in-
sure establishment and survival of plantings. Trees best
suited and having good survival are Rocky Mountain ju-
niper, eastern redcedaz, ponderosa pine and Siberian elm.
Shrubs best adapted are akunkbush sumac and lilac.
Rangeland wildlife such as antelope, cottontail and
coyote are best adapted on these soils. Proper livestock
grazing management is necessary if livestock and wildlife
share the range. Livestock watering facilities are also im-
portant and are utilized by various wildlife species. The
position of these sods in relationship to croplands makes
them valuable as escape cover areas for openhmd wildlife,
especially pheasants. The relief, natural springs and na-
tive vegetation provide food and cover. Areas of these
so>7s provide sites that can be readily developed and
managed for wildlife.
Slope is the primary ]'uniting soil feature where these
sods are used for homesites or other urban developments.
Intensive engineering designs and measures aze needed
to minimize the slope limitation. Where the soils are con-
sidered for a sewage Lagoon system, special sealing
methods are required to overcome excessive seepage.
Capability subclass VIe nonhrigated.
26-Els loamy sand. This is a deep, somewhat poorly
drained soft on low terraces and bottoms along the South
Platte River. It formed in calcareous, stratified sandy al-
luvium underlain by mottled sand and gravel Average
annual precipitation ranges from 13 to 19 inches. Slopes
are nearly level
Included in this unit are small azeas of Alda loam and
Fluvaquentic HapLuluolls.
Typically the surface layer is grayish brown loamy sand
about 6 inches thick. The underlying layer is light
brownish gray loamy fine sand about 11 inches thick over
light gray, calcareous, mottled loamy fine sand that is
stratified with thin lenses of sit loam and extends to 58
inches. Below a depth of 58 inches is a mixture of
brownish, mottled coarse sand and gravel
Permeability is rapid. Effective rooting depth is 60
inches or more. Available water capacity is low. Surface
runoff is slow, the erosion hazard is slight, and the soi
blowing hazard is moderate. A fluctuating water table oc-
curs below 20 inches during the winter and spring
months This soil is subject to occasional flooding during
late spring and summer months.
This soi is used for irrigated cropLmd and grazing. Al-
falfa, corn, and sugaz beets are the main crops grown.
In irrigated cropland areas the main concerns of
management are efferent use and distribution of water,
fertility maintenance and protecting the soil from blow-
ing. Sprinkler irrigation is best suited, but the size and
position in the landscape of these areas makes the border
or furrow irrigation method the one normally used. Ir-
rigation frequency should be often and length of runs
29
short for the most efficient application of irrigation
water. Applications of manure and commercial fertilizers
containing nitrogen and phosphorus are needed to main-
tain soil productivity. Leaving crop residues on the sur-
face protects the soil from blowing during periods when
there are no growing crops.
The rangeland vegetation of this soil consists mainly of
tall prairie grasses, including sand bluestem, switchgrass,
prairie cordgrass, tittle bluestem, sand reedgrass, sedge,
and indiangrass. These produce an abundance of forage
that can be cut for grass and hay. Management of the
grazing is mandatory on these soils in order to maintain
the productive grasses. Proper grazing and planned graz-
ing systems that include deferment periodically during
the growing season aze effective in maintaining or im-
proving the rangeland vegetation. Chemical or mechanical
brush management is beneficial where dense stands of
sand sagebrush encroach on this soil. Lands taken out of
cropland or depleted by overgrazing can be seeded to
adapted rangeland grasses. Fencing is essential in
separating these soils from other soils in order to apply
needed treatment and grazing systems.
Windbreaks and environmental plantings are generally
well suited to this soil. The somewhat poorly drained con-
dition and abundant competing vegetation are the prin-
cipal concerns in establishing tree and shrub plantings.
Special care consisting of summer fallow, continued cul-
tivation for weed control, and selection of adapted plants
is needed to insure establishment and survival of
plantings. Trees beat suited and having good survival are
plains cottonwood, golden wffiow, Colorado blue spruce,
Rocky Mountain juniper and eastern redcedaz. Shrubs
beat suited are American plum, purple willow, common
chokecherry and redosier dogwood.
This is an important soil for wildlife because of its in-
tensive use for cropland and its sesociatian with the
South Platte River. Under irrigation, it is an important
food producer for waterfowl, pheasants and deer. All uti-
ize crop residues which occur as aftermath following haz-
vest. Wildlife values can be enhanced by developments of
tree and shrub plantings and undisturbed nesting cover of
grasses and legumes. In the presence of a water supply,
waterfowl could be attracted to the area by development
of shallow water areas.
Where areas are used for homesites or other urban
developments, the primary limiting soil features aze a
water table at a depth of 20 to 40 inches and occasional
flooding. Special sewage systems must be anticipated.
Septic tank absorption fields will not function properly
because of the high water table. Homesites and other
urban development construction will require compensat-
ing measures and designs to overcome the water table
condition and flood hazazd. Special road designs aze also
needed that will take into account the frost action poten-
tial of the soil. Capability subclass IVw nonirrigated, IVw
irrigated.
27-Epping loam, 3 to 9 percent slopes. This is a shal-
low, well drained soil on uplands in the northwestern part
