The Aquolls, uhlch have dark <br />colored surface layers, make up about 65 percent of the mapping unit. <br />The Aquen[s, which have lighter colored surface layers, make up about <br />25 percent. About 10 percent is Aqunlls and Aquepts, flooded, and <br />Bankard sandy loam. <br />These are deep, poorly drained soils. They formrd fn recon[ alluvium. <br />Typically [hey have motCled, mildly [o moderately alkaline, loamy or <br />clayey surface layers and underlying ma[e[tal, and arc underlain by <br />sand or sand and gravel vltl,in 48 Inches. They niay or may not have a <br />gleycd,layer in the underlying material. <br />Pfost of these foils arc subJcct ro Clooding.
