Ncl(1 Series
<br />Tile. 1\'~lcl series consists of well-drained, nearly level
<br />lolls on uplands. These soils formed in wind=trorked'
<br />loann~ materials.
<br />In n reprrsentnti.ve Profile, the surface layer is brown
<br />loam about G inches thick. It is noncalcnreons. The upper
<br />part of the subsoil is dark-browp clay about G inches
<br />thick. 7t. is noncnlcnremis. The lower part of the subsoil
<br />is )talc-hrmvn and verv fine sandy loam about. 20. inches

<br />rang~e from 30 to 700 acres in size. 5)trfnce• runoff is
<br />litedium, and the hazard of ~vnter et•osibn :is moderate to
<br />severe: The hazard of soil blowitlg is severe i» dryfnrmed
<br />stuns if rainfall is below normal.
<br />Included in mapping .are some small areas where
<br />slopes are less than 1 ercent. Also included are some
<br />smell areas of Adana loam that are in most sloping
<br />areas.
<br />Almost all of this Weld soil is cultivated. A fats areas
<br />are irrigated. Scattered areas throughout the county are
<br />in native grass. Capability unit IIe-1, irrigated, and
<br />IIIc-1, nontrrignted; Loamy Plains range site; tree plant-
<br />illg suitability group 1.'
<br />Weld-Deertrail complex, 0 to 3 percent slopes 1WtBl.-
<br />This complex is on uplands. About 60 percent of it is
<br />SVeld loam, and 40 percent is Deertrail loam. The Weld
<br />soil is .similar to 1'ireld loam, 1 to 3 percent slopes, but
<br />it is closely intermingled with patches of the Deertrail
<br />soil. The patches are bare and commonly are called
<br />slickspots.
<br />Arens of the complex in llntive pasture can be readily
<br />recognized Liy the bare spots that are chnractcristic of
<br />Deertrail soils. These have n growth of bu»chgrass or
<br />buffnlogrnss around their. edges and nre'surrounded by
<br />a cover of drama grasses. In cultivated fields the slick-
<br />spots are difficult to see in some areas, liut they cause
<br />crop growth to be stunted and the stirfacc layer to crust.
<br />i\Itielt of this.comple>t is dryfnrmed; but n large acre-
<br />nge remnins'in native grass. The maid crops are winter
<br />whelit and sorghums. Runoff is slow. The hazards of
<br />tvntcr erosiolt qnd soil blowing nt•e moderate, but they
<br />iiicreasc in severity if gullies .form. Soil blowing is a
<br />severe hazard if the soils are dryfnrmed in years tyhen
<br />rainfall is not sufficient. Capability •unit IVs-2, nonirri-
<br />gnted; tree planting suitability group 3. Weld soils,
<br />Loamy Plants range site. Deertrail soils, Alkaline Plains
