The map unit descriptions in this report, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils.Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently,every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. The Map Unit Description (Brief, Generated) report displays a generated description of the major soils that occur in a map unit. Descriptions of non-soil (miscellaneous areas) and minor map unit components are not included. This description is generated from the underlying soil attribute data. Additional information about the map units described in this report is available in other Soil Data Mart reports,which give properties of the soils and the limitations, • capabilities, and potentials for many uses.Also,the narratives that accompany the Soil Data Mart reports define some of the properties included in the map unit descriptions. Report—Map Unit Description (Brief, Generated) Weld County, Colorado, Southern Part Map Unit: 56—Renohill clay loam, 0 to 3 percent slopes Component: Renohill (85%) The Renohill component makes up 85 percent of the map unit. Slopes are 0 to 3 percent. This component is on plains. The parent material consists of residuum weathered from shale. Depth to a root restrictive layer, bedrock, paralithic, is 20 to 40 inches.The natural drainage class is well drained.Water movement in the most restrictive layer is moderately low. Available water to a depth of 60 inches is low. Shrink-swell potential is high. This soil is not flooded. It is not ponded. There is no zone of water saturation within a depth of 72 inches. Organic matter content in the surface horizon is about 2 percent.This component is in the R067BY042CO Clayey (formerly Clayey Plains) ecological site. Nonirrigated land capability classification is 4e. Irrigated land capability classification is 3e.This soil does not meet hydric criteria. The calcium carbonate equivalent within 40 inches, typically, does not exceed 3 percent. •Uy5T Natural Resources Web Soil Survey 2.0 6/19/2007 Conservation Service National Cooperative Soil Survey Page 1 of 2 • • Map Unit Description(Brief,Generated)—Weld County,Colorado,Southern Part • Component: Aquic Argiustolls (1%) Generated brief soil descriptions are created for major components.The Aquic Argiustolls soil is a minor component.

Only that part of the soil between depths of 24 and 60 inches is evaluated.The ratings are based on the soil properties that affect absorption of the effluent, construction and maintenance of the system, and public health. Saturated hydraulic conductivity (Ksat), depth to a water table, ponding, depth to bedrock or a cemented pan, and flooding affect absorption of the effluent. Stones and boulders, ice,and bedrock or a cemented pan interfere with installation. Subsidence interferes with installation and maintenance. Excessive slope may cause lateral seepage and surfacing of the effluent in downslope areas. Some soils are underlain by loose sand and gravel or fractured bedrock at a depth of less than 4 feet below the distribution lines. In these soils the absorption field may not adequately filter the effluent, particularly when the system is new.As a result, the ground water may become contaminated. The ratings are both verbal and numerical. Rating class terms indicate the extent to which the soils are limited by all of the soil features that affect the specified use. "Not limited"indicates that the soil has features that are very favorable for the specified use. Good performance and very low maintenance can be expected. "Somewhat limited"indicates that the soil has features that are moderately favorable for the specified use. The limitations can be overcome or minimized by special planning, design, or installation. Fair performance and moderate • maintenance can be expected."Very limited"indicates that the soil has one or more features that are unfavorable for the specified use.The limitations generally cannot be overcome without major soil reclamation, special design, or expensive installation procedures.Poor performance and high maintenance can be expected. Numerical ratings indicate the severity of individual limitations. The ratings are shown as decimal fractions ranging from 0.01 to 1.00. They indicate gradations between the point at which a soil feature has the greatest negative impact on the use(1.00) and the point at which the soil feature is not a limitation (0.00).
