<br />Gosi.^n loam, 1 to 3 percent slopes IGoBI•-This soil
<br />7ccurs as small areas on rho side slopes of drainagnways
<br />in t11e northcastetn quazter of the county. The surface
<br />layer is loam or light clay loam about 4 to 12 inches
<br />thick. Tho suUsotl, about 14 inches thiclr, is silt loam
<br />or clay loam. Limo occurs at a depth of 15 to 30 inches.
<br />Inciudect in mappiug were small areas of Wiley loam
<br />anti Baca clay loam.
<br />This soil has moderate water intalto. Surface runoff
<br />is medium.
<br />1\Iosl of the acreage is cultivated. Wheat and' sorghum
<br />arc the main crops. Land IeveIing is necessary for uni-
<br />form application of orator. Durin pperiods of drought,
<br />derp listing and chiseling are nce~od. Stubble mulchmg
<br />anti stripcropping help control soil blowing. On range,
<br />propm• managmnmtt practices such as deferred and ro-
<br />tation Brazing are necessary for maintaining and im-
<br />proving the vegetative cover. (Cappability unit IIe-1,

<br />steep soils on uplands.
<br />The surfn.ce layer of this ]and typo is light-colored

<br />to light clay Loam.

<br />All of thn acreage is in native vegetation that consists
<br />mainly of side-oats gralpa, blue grarna, buffalograss, and
<br />yucca. (Capability writ VIIs-2, nonirrigated; Gravel

<br />Harbord Series
<br />The I-Iarbord series consists of deep, nearly level to
<br />gently sloping, light-colored loams on uplands.
<br />In a typical profile the surface layer, about 3 inches
<br />thick, is Urown, very strongly calcareous loam. The suU-
<br />soil is Urown, noncnlcareous silty clay loam about 13
<br />inches thick that rests nn nn older buried soil about 13
<br />inches thick. Tho Uuried soil is clay loam and contains
<br />many white lime strcalcs and mottles. Below a depth of
<br />about 20 inches is pink, very strongly calcareous clay

<br />in the w~stent half of the county; and, near Walsh,
<br />areas of Wiley loam.
<br />This soil absorbs water well. Suzfaco runoff is slow, and
<br />available water capacity is high. Soil blowing is the
<br />major hazard.
<br />About 70 percent of the acreahe is cultivated. Wheat
<br />and sorghum are the main crops. P'ez•tilizing, use of

<br />improve production. Stubble mulching and stripcroppin~
<br />help control soil Ulowing, and during periods of drought,
<br />deep ]istinh and chiseling also help. Proper ranee man-
