<br />Surface runoff is medium, and the erosion hnr~:nl is low.
<br />This soil is used almost enlln•ly fur tminlted crop.. It
<br />is suited to all crops commonly I,m+wn in the area, includ-
<br />ing corn, sugar beets, beans, :dfalfa, small grain, potatoes.
<br />and onions. An example of a suitabe cropping system is :t
<br />to 4 years of alfalfa followed by corn, corn for silage,
<br />sugar beets, small grain, or beans. Land leveling, ditch
<br />lining, and insl.alling pipelines may be needed for proper
<br />water application.
<br />All methods of irrigation are suitable, but furrow ir-
<br />rigation is the most common. Barnyard manure and com-
<br />mercial fertilirar art• needed fur top yields.
<br />Windbreaks and environmental phm[ins of [errs and
<br />shrubs commonly grown in [hr area are generdly will
<br />suited to the=. soil Cultivation to control cumpa•ting
<br />vegetation should hr continued for as many years as
<br />pos-gible following planting. Trees [het are best suited and
<br />have good sun+ival are Ra•ky Mountain juniper, eastern
<br />redredar, ponderosa pine, Siberian elm, Russian-olive, and
<br />hackberry. The shrvbs best suited are skunkbush sumac.
<br />lilac, Siberian peashrvh, and American plum.
<br />This soil can praluce habitat elements that are highly
<br />suitable for opanland wildlife including pheasant, cotton-
<br />tail, and mourning dove. Such crops ds wheat, corn, and
<br />. alfalfa provide ;unable habitat for upenland wildlife,
<br />especially pheasant. Tree and ahrvb plantings and
<br />undisturbed netting cover would enhance openland wil-
<br />dlife population.,.
<br />This Altvan soil has fair to go«I potential for urban
<br />and recreational development. The chief limiting soil fea-
<br />tures Cor urban development are the shrink-swell pdrn-
<br />tial of the subsoil as it wets and dries and the rapid
<br />permeability of [he sand and gravel substratum. Septic
<br />tank absorption fields function properly, but in places the
<br />substratunf does not contain enough fines to properly
<br />filter the leachate. Sexage lagoons require sealing.
<br />Lawns, shrubs, and trees grow well. Capability subclass

<br />3-Aquolls and Aquents, gravelly substratum. This
<br />nearly level map unit is on bottom land, and flood plains
<br />of all the major streams in the survey aria. Aq•~olls,
<br />which have a dark colored surface layer, make up about
<br />:uul leveling and arc used for vngated crop..
<br />"fhc potential naliw• vcgvtatiun is dominated by alkali
<br />sxcaton, switc•hgrass, and western wheatgrasa. Saltgrass,
<br />sedge, rush, and alkali blucgra-w are also prominent.
<br />Potential production ranges from a,INlO pounds per acre in
<br />favorable years to °lMNI pounds in unfavorable years. As
<br />range condition deteriorates, the switchgrass, alkali
<br />sacaton, and western wheatgrass decrease and saltgrass,
<br />sedge, and rush increase.
<br />Management of vegetation should he ba-•x•tl on taking
<br />half and (caving half of the total annual production. Seed-
<br />ing is difficult and costly because numerous tillage prac-
<br />tices are required to eliminate the saltgress sod.
<br />Svritchgrass, western wheatgress, :dkxli sar:don, tall
<br />wheatgriss, and t;dl fescue are suitable Ibr s~rding. They
<br />can be arrdod into a clean, firm seedbed. Seedbed
<br />preparation usually requires more than 1 year to
<br />eliminate the sallgrass sod. A grass drill should be used.
<br />Seeding early in spring has proven moat successful.
<br />Wethmd wildlife, especially waterfowl, utilize this unit.
<br />The wetland plants provide nesting and protective cover,
<br />as well a_` some food. The nearby irrigated cropland,
<br />where wildlife obtain much oC their food and find protec-
<br />tive cover, makes this unit valuable to both wetland and
<br />openland wilJlife.
<br />Openland wildlife, especially pheasant, use this unit for
<br />cover amt nesting. Deer find excellent cover in some
<br />arras.

<br />area. Aquolls, which have a dark colored surface layer,
<br />make ttp about 55 percent of the unit. Aquepts. which
<br />have a lighter colored surface layer, make up shout '?5
<br />percent. About °_ll percent is soils that are well drained
