These nearly level soils are on bottom lands and flood plains of all the major streams in the survey area. The Aquolls, which have dark colored surface layers , make up about 65 percent of the mapping unit. The Aquepts, which have lighter colored surface layers, make up about 25 percent. About 10 percent is Aquolls and Aquepts , flooded, and Bankard sandy loam. — These are deep, poorly drained soils that formed in recent alluvium. The A and B horizons range from absent (0") to 18". Typically they have mottled, mildly to moderately alkaline, loamy or clayey surface layers and underlying material , and are underlain by sand or sand and gravel at ldepths of 24 to 48 inches. They may or may not have a gleyed layer in the underlying material . Most of these soils are subject to flooding. The watertable is at or near the surface early in the spring and recedes to about 48 inches by late fall in some years.

They may or may not have a gleyed layer in the underlying material. • Most of these soils are subject to flooding. A watertable is at or near the surface early in the spring and recedes to as deep as 48 inches by late Call in some years . These soils arc used for rangeland and wildlife habitat . Some small areas have been reclaimed by ma4or drainage and leveling operations and is farmed to irrigated crops . The potential native vegetation on these soils is dominated by alkali sacaton, switc'igrass and western whcatgrass . Saltgrass , sedge , rush and alkali bluegrass are also prominent. Potential production ranges from 3000 pounds per acre in favorable years to 2000 pounds per acre in unfavorable years . When range condition deteriorates , switchgrass , 951,724 alka1 saraton and western wheatrrass dectcnse and salt vra ss , sedge and rush increase . Management of vegetation on this soil should be based un taking half and leaving half of the total annual production. Seeding on this site is difficult and costly since numerous tillage practices are requited to eliminate the saltgrass sod . Swit. ;ass , western •atgrass , alkali sacaton , tall wheatrrass and tall fescue are suitable for seeding. For successful seeding a clean , firm seedbed -- usually requires more than one year to eliminate the saltgrass sod -- and a ;;rags drill should be used . Early spring seeding has proven most successful . I;etland wildlife , especially waterfowl , utili; e these areas . The availability of moisture due to the wetness of this soil allows pro- duction of wetland plants that prnvide nesting and protective cover, as well as some food for waterfowl. The luxtaresition of this soil to irrigated cropland areas where wildlife obtai n much of their food , along with the cover provided , make this soil valuable to both wetland and openland wildlife . Openland wildlife , especially pheasants , use these areas for cover and nesting , while they also provide excellent cover for deer when found is areas inhabited by deer. Management for wildlife would include prevention of overgrazing by livestock, protection from unplanned fire , and prevention of drainage. ts'here livestock are present , tti.ese valuable wildlife areas should be fenced to prevent unwanted encroachment and overuse by livestock. 951394 These soils have a good potent in1 as a source of sand .and gravel .

Surface runoff is medium and erosion hazard is node rate. Where irrigated this soil is suited to the commonly grown crops in the area . However, perennial grasses and alfalfa ur close crown crops should be grown at least 50 pdreent of the time. Close grown crops and pasture can be irrigated with contour ditches and corrugations. Furrows , contour furrows and cross slope furrows will work on row crops . Sprinkler irrigation is also recomnended . • Minimum tillage and crop residue utilization will help control erosion. Fertility maintenance is important. Crops grown on these soils respond to fertilizer applications of phosphorous and nitrogen. 951304 ' Hello
