30IL 5[; RCEY _Uw in this as=_ociation are TruclROn soils ou the crests of lcrtobs and low-lying areas called we.t weather lakes. The low areas are nc:u the \unn soils and general)}' are less than 5 acres in size. They are ponded after beery rains, for there is a dense clayey layer below the surface. JLost of this association is used for cultivated crops. All crops commonly grown in the county grow well, but wheat is the principal crop. Lt many places soil blowing is severe on ilia crest of latobs, but it, and water erosion as well, is reduced if crop residue is left on the surface. 8. Truckton-Bresser• Association Deep, rolling, Zoamy and sandy soils that haze a Zoamy subsoil; on tcplands This association is on uplands. It occupies small areas on the eastern side of major drninagewavs throughout the western and central parts of the county.-It consists of deep soils that formed in nonlirny, sandy material deposited by wind. The topography is rolling; most slopes are between 3 and 8 percent, but some are as much as 15 percent. This association occupies about 14 percent of the county. About 50 percent is made tip of Tntclcton soils, 2i percent of Bresser soils, and the remaining 23 percent of minor soils. Truckton sails have a dark grayish-brown loamy sand surface laver about 6 inches thick. Their subsoil is brown- ish sandy loam that estends to a depth of 30 inches It is hard or very hard when dry. These soils do not contain a limy laver but hate streets of lime in the underlying material. The Brewer soils occur rat the lower parts of slopes. They hate a du•k gra}'ish-Drown sandy loam surface later about 5 inches thick. Tltcir subsoil is dark-brown and ]igltt- brown sanclt- loam in the upper and Lotter parts rand is brown sandy clan loam in t.ho midclle part. Like Truckton soil=_, Bresser soils do not contain a limy layer, but they have streaks of lime in the under)}'ing material. Escepc iu bare areas. mater is taken into the Truckton soils rapid)}-. but rioter is taken into the Bresser soils at a moderaate to rapid rate. Both I:iuds of soils have moderate available water holding capacity. also in the associatimt arc the Blnkehutd, Ascalon, and \unn soils and tote, wet areas called wet weather lakes. The low wet arras :enernllc are. not. more than 2 acres in size. Blakeland ;oils norntallc or-cur in small areas on ridgetops near Trucl.-ton soils. The \unn soils rare in small areas nest to the wet tvcather la.lces. S:utdstone and shale crop out in small accts at the base of steep slopes Wert to the m;tjor drainagen-a.cs. About one-fourth of this association is used for culti- vated crops. and the rest is in _rass and is used for grazing. Among t.be natit-e _racses air blue grams, needle-and- thread, s:tncL-md.:uxl little bhtestent. Cultivated crops grow fairlc ttcll on the soils of ibis association, but soil blowiri~ is severe in cultivated areas on the crest of knobs and rolling areas. Stubble umlcliin_ and stripcropping are arnon_ the practims needed far controlling soil blotcine and catserting moisture. 9. Stapleton-Bresser association .Moderately steep soils that are loamy tlrrougho+d; nrod- eralely deep artd deep aver arkosic savtdstane; mr, ioot/~iiLs This association is on foothills at the highest eletations in the counts. Slopes generally rnnge from 8 to 25 percent. The association consists of moderately deep and deep, loamy soils on ppoorly consolidated beds of stnd and silt raised with windblotcn sandy deposits. Tltis association occupies about 3 percent of the county. About 43 percent is made up of Stapleton soils, 30 ercent of Bresser soils, and the remaining 28 percent of minor soils. The Stapleton soils are moderately deep. Their surface layer, about 8 inches thick, is grayish-brown sandy loam that contains a noticeable amount of mica and fine gravel. Below this ]a per is light brownish-gray and pale-yellow sandy loam that contains much fine gravel. Poorly con- solidated beds of fine gravel and siltstone occur nt a depth of about 16 inches. The Bresser soils are deep. They have a dark prayish- brown sandy loam surface layer about 5 inches thick. The subsoil, about 23 inches thick, is dark-brown, brown, and light-brotcn s,•mdy loam rand sandy clay loam that is hard or eery hard when dry. Interbedded shale and fine grncel orwind-deposited scud occurs below a depth of 3 feet. Both Stapleton and Bresser soils have a moderate to rapid rnte of water intake. Available water holding capac- ity is low in the Stapleton soils and moderate in the Bresser soils. Both hinds of soils generally etc free of lime. Tltey are susceptible to soil blowing and water erosion. Also in this association are the Buick, Litre, and Reno- ltill soils arid. in draws, areas of frequently flooded loamy and sandy alluvium. Cobblestones, as much as 12 inches in diameter, occur on the surface of the Litre soils, and many gullies hate farmed in the areas consisting of loamy and sandy alluvium. \Lost of this association is in native grass and western telloty pine. Cattle grazing is the main use. The pine trees have little or no commercial value, but they provide shade for livestock ;tad areas where the trees grow can be de- teloped for recrcttional ups. Because of the slope, n-ater erosion generally is a set-ere hazard in cultivated areas. 10. Fondis-Weld Association Deep, nearly level and gently sloping, loam soils that haze a clayey layer in the .sabsoil; lor»ted rrw,xnly in silty, grind-deposited material; on foothills 'this association is on uplands in the western part of the county. It consists of deep soils that formed inninly in silty material deposited bt the wind. Slopes range from 1 ~ 5 percent in most places. but nest to drninageways they are as mttclt as 0 percent. This association occupies about 8 percent of the county, About i0 percent is made up of Fondis soils, 22 percent of Rreld soils. rand the remaining 8 percent of minor soils. The Fondis soils hate a surface layer of dark grnyish- brown silt loam to silty clay loam about 8 inches thick. The subsoil. to a depth of about 32 incites, is dark-brown clot and pale-brotan silty clot loam. Below that depth arc I-2
