Soil Classification#59: Shingle Loam, 3 to 9 percent slopes
69—Shingle loam,3 to 9 percent slopes.This is a shal-
low, wee drained soil on upland hills and ridges at eleva-
tions of 4,860 to 5,200 feet. It formed in residuum from
shale. Included in mapping are some small outcrops of
shale and sandstone.
Typically the surface layer is grayish brown loam about
4 inches thick.The underlying material Is light yellowish
brown clay loam about 10 inches thick Shale is at a depth
of about 16 inches.
Permeability is moderate. Available water capacity is
low. The effective rooting depth is 10 to 20 inches. Sur-
face runoff is medium to rapid,and the erosion hazard is
moderate.
The potential native vegetation on this soil is.
dominated by alkali sacaton, western wheatgraas, and
blue grams. Buffalograse, sideoats grams. needle-
andthread,little bluestem,sedge, winterfat,and foaming
saltbusb are also present. Potential production ranges
from 800 pounds per acre in favorable years to 600
pounds in unfavorable yearn. As range condition deteri-
orates, the mid grasses decrease and forage production
P drops. Undesirable weeds and annuals invade the site as
range condition becomes poorer.
Management of vegetation on this soil should be band
on taking half and leaving half of the total annual produc-
tion.Seeding is desirable if the range is in poor condition.
Western wheatgraee, blue grams, alkali sacaton. sideoats
grams,little bluestem,pubescent whestgrass,and crested
wheatgrase are suitable for seeding. The vase selected.
should meet the seasonal requirements of livestock It can
be seeded into a clean,firm sorghum stubble or it can be
drilled into a firm prepared seedbed. Seeding early in
spring has proven most successful.
Windbreaks and environmental plantings are generally
not suited to this soil. Oaeite investigation is needed to
determine If plantings are feasible.
Rangeland wildlife. such as antelope, cottontail, and
coyote,are best sated to this soil.Bedtime forage

tion is typically low, grassing management needed

This-soil is suited to limited cropping-
cropping is hazardous because of erosion. The cropping
system should be limited to such close grown crops as al-
falfa, wheat, and barley. The soil is also suited to ir-
rigated pasture. A suitable cropping system is 3 to 4
years of alfalfa followed by 2 years of corn and small
grain and alfalfa seeded with a nurse crop.
Closely spaced contour ditches or sprinklers can be
used in irrigating close grown crops. Contour furrows or
sprinklers should be need for new crops. Application of
commercial fertilizer helps in maintaining good produc-
tion
The potential native vegetation is dominated by blue
grama. Several mid grasses, such as western wheatgrass
and rieeddeandthread, are also present Potential produc-
tion ranges from 1,600 pounds per acre in favorable years
to 1.000 pounds in unfavorable years. As range condition
deteriorates, the mid grasses decrease; blue granite, buf-
falograss, anakeweed, yucca, and fringed sage increase:
, and forage production drops Undesirable weeds and an-
nuals invade the site as range condition becomes poorer.
