SOILS DESCRIPTION <br /> ADAMS COUNTY, COLORADO <br /> LOAMY ALLUVIAL LAND , MODERATELY WET (Lw) is in many drainageways <br /> throughout the county. It is predominantly in the broader <br /> drainageways that have a high water table and that formerly had poor <br /> drainage. The areas are broad in the larger and more gently sloping <br /> drainageways , especially in the South Platte River bottom. All are <br /> subject to damage , in varying degrees , by flooding from adjacent <br /> slopes and main stream channels . Included in mapping are small areas <br /> of Nunn loam, Satanta loam, Wet alluvial land , and Loamy alluvial <br /> land , gravelly substratum. <br /> The soils are moderately deep , ranging from 20 to 36 inches in <br /> depth , over unconsolidated sand and gravel . They are dark-colored loam <br /> to clay loam in texture and generally are stratified. They are <br /> normally noncalcareous , but they are moderately influenced by soluble <br /> salts in places. Thin lenses of sand , silt , or fine gravel may be in <br /> any of the layers . <br /> The soils of this land type absorb water at a moderate to slow <br /> rate , and the available water capacity is high. Artificial drainage <br /> is generally needed to grow crops . Natural fertility is high , but <br /> under the intensive management used on these soils , artificial <br /> supplements are needed. <br /> Most of this land type is irrigated. In these areas , crops such <br /> as sugar beets , corn , small grains , and vegetables can be grown . <br /> A1_ al_ a and irrigated pasture are well adapted. Western wheatgrass , <br /> sal_grass , blue =gamma , and swi tcngrass are =rown in some areas . <br /> Capabi1 ` zy Un: t I !
