Map Unit Description(Brief,Generated)—Weld County,Colorado,Southern Part 8th Street <br /> Map Unit Description (Brief, Generated) <br /> The map units delineated on the detailed soil maps in a soil survey represent the <br /> soils or miscellaneous areas in the survey area. The map unit descriptions in this <br /> report, along with the maps, provide information on the composition of map units <br /> and properties of their components. <br /> A map unit delineation on a soil map represents an area dominated by one or <br /> more major kinds of soil or miscellaneous areas. A map unit is identified and <br /> named according to the taxonomic classification of the dominant soils. Within a <br /> taxonomic class there are precisely defined limits for the properties of the soils. <br /> On the landscape, however, the soils are natural phenomena, and they have the <br /> characteristic variability of all natural phenomena. Thus, the range of some <br /> observed properties may extend beyond the limits defined for a taxonomic class. <br /> Areas of soils of a single taxonomic class rarely, if ever, can be mapped without <br /> including areas of other taxonomic classes. Consequently, every map unit is <br /> made up of the soils or miscellaneous areas for which it is named and some <br /> minor components that belong to taxonomic classes other than those of the <br /> major soils. <br /> The Map Unit Description (Brief, Generated) report displays a generated <br /> description of the major soils that occur in a map unit. Descriptions of non-soil <br /> (miscellaneous areas) and minor map unit components are not included. This <br /> description is generated from the underlying soil attribute data. <br /> Additional information about the map units described in this report is available in <br /> other Soil Data Mart reports,which give properties of the soils and the limitations, <br /> capabilities, and potentials for many uses.Also, the narratives that accompany <br /> the Soil Data Mart reports define some of the properties included in the map unit <br /> descriptions. <br /> Report—Map Unit Description (Brief, Generated) <br /> Weld County, Colorado, Southern Part <br /> Map Unit: 3—Aquolls and Aquents, gravelly substratum <br /> Component:Aquolls(55%) <br /> The Aquolls component makes up 55 percent of the map unit. Slopes are 0 to 3 <br /> percent. This component is on swales, major streams, flood plains. The parent <br /> material consists of recent alluvium. Depth to a root restrictive layer is greater <br /> than 60 inches. The natural drainage class is poorly drained. Water movement in <br /> the most restrictive layer is moderately high.Available water to a depth of 60 <br /> inches(or restricted depth) is moderate. Shrink-swell potential is low. This soil is <br /> frequently flooded. It is not ponded.A seasonal zone of water saturation is at 27 <br /> inches during March, April, May, June, July. Organic matter content in the surface <br /> horizon is about 2 percent. This component is in the R067BY035CO Salt <br /> Meadow ecological site. Nonirrigated land capability classification is 6w. This soil <br /> meets hydric criteria. There are no saline horizons within 30 inches of the soil <br /> surface. <br /> USDA Natural Resources Web Soil Survey 12/21/2022 <br /> Conservation Service National Cooperative Soil Survey Page 1 of 4 <br />
