SOILS DESCRIPTION <br /> ADAMS COUNTY, COLORADO <br /> WET ALLUVIAL LAND (Wt) is on the nearly level bottom lands of the <br /> larger streams next to stream channels throughout the county. The <br /> areas range from 20 to 150 acres in size. This land type is wet most <br /> of the time and is flooded by streamflow once to several times a year <br /> during periods of high water. Included in mapping are small areas of <br /> Loamy alluvial land , moderately wet , a few small sand and gravel bars , <br /> and areas underlain by heavy clay, commonly called oxbows. <br /> The materials are extremely variable in texture; they consist of <br /> stratified layers of dark-colored silt , loam, and clay. The layers <br /> are generally less than 6 inches thick and are underlain by sand, fine <br /> sand , and some gravel at depths of 1 to 3 feet. They are wet at a <br /> depth of 2 feet most of the time and are commonly wet to the surface <br /> throughout, the growing season . Natural fertility is moderate to good. <br /> Areas of this land type have a vegetative cover of water-tolerant <br /> plants , such as cattails and sedges , and are not suitable for <br /> cultivation , because of the hazard of flooding from streams and a high <br /> water :able . Under improved managemnet , the production of native <br /> grass for grazing or hay is good. Generally a few cottonwood trees <br /> and willows are present .
