Map Unit Description(Brief,Generated)—Weld County,Colorado,Southern Part 8th Street <br /> Component:Aquents, gravelly substratum (30%) <br /> The Aquents, gravelly substratum component makes up 30 percent of the map <br /> unit. Slopes are 0 to 3 percent. This component is on stream terraces. The <br /> parent material consists of recent alluvium. Depth to a root restrictive layer is <br /> greater than 60 inches. The natural drainage class is poorly drained. Water <br /> movement in the most restrictive layer is moderately high.Available water to a <br /> depth of 60 inches(or restricted depth) is moderate. Shrink-swell potential is low. <br /> This soil is frequently flooded. It is not ponded.A seasonal zone of water <br /> saturation is at 15 inches during March, April, May, June, July, August, <br /> September. Organic matter content in the surface horizon is about 1 percent. <br /> This component is in the R067BY035CO Salt Meadow ecological site. <br /> Nonirrigated land capability classification is 6w. Irrigated land capability <br /> classification is 6w. This soil meets hydric criteria. The calcium carbonate <br /> equivalent within 40 inches, typically, does not exceed 5 percent. The soil has a <br /> very slightly saline horizon within 30 inches of the soil surface. <br /> Component: Bankard (10%) <br /> Generated brief soil descriptions are created for major soil components. The <br /> Bankard soil is a minor component. <br /> Component: Ustic Torrifluvents (5%) <br /> Generated brief soil descriptions are created for major soil components. The <br /> Ustic Torrifluvents soil is a minor component. <br /> Map Unit: 10—Ellicott-Ellicott sandy-skeletal complex, 0 to 3 percent slopes, <br /> rarely flooded <br /> Component: Ellicott, rarely flooded (65%) <br /> The Ellicott, rarely flooded component makes up 65 percent of the map unit. <br /> Slopes are 0 to 3 percent. This component is on drainageways on uplands,flood <br /> plains on intermittent streams on uplands. The parent material consists of <br /> noncalcareous, stratified sandy alluvium. Depth to a root restrictive layer is <br /> greater than 60 inches. The natural drainage class is excessively drained. Water <br /> movement in the most restrictive layer is high. Available water to a depth of 60 <br /> inches (or restricted depth) is very low. Shrink-swell potential is low. This soil is <br /> rarely flooded. It is not ponded. There is no zone of water saturation within a <br /> depth of 72 inches. Organic matter content in the surface horizon is about 1 <br /> percent. This component is in the R067BY031 CO Sandy Bottomland ecological <br /> site. Nonirrigated land capability classification is 7s. Irrigated land capability <br /> classification is 4e. This soil does not meet hydric criteria. There are no saline <br /> horizons within 30 inches of the soil surface. <br /> Component: Ellicott sandy-skeletal, rarely flooded (25%) <br /> USDA Natural Resources Web Soil Survey 12/21/2022 <br /> Conservation Service National Cooperative Soil Survey Page 2 of 4 <br />
