Soil Information for All Uses <br /> Suitabilities and Limitations for Use <br /> The Suitabilities and Limitations for Use section includes various soil interpretations <br /> displayed as thematic maps with a summary table for the soil map units in the selected <br /> area of interest.A single value or rating for each map unit is generated by aggregating <br /> the interpretive ratings of individual map unit components. This aggregation process <br /> is defined for each interpretation. <br /> Land Classifications <br /> Land Classifications are specified land use and management groupings that are <br /> assigned to soil areas because combinations of soil have similar behavior for specified <br /> practices. Most are based on soil properties and other factors that directly influence <br /> the specific use of the soil. Example classifications include ecological site <br /> classification, farmland classification, irrigated and nonirrigated land capability <br /> classification, and hydric rating. <br /> Ecological Site Name: Plant Associations, Region 2 <br /> Forest Service (Russell Painter ) <br /> An ecological site name provides a general description of a particular ecological site. <br /> For example, "Loamy Upland" is the name of a rangeland ecological site. An <br /> "ecological site" is the product of all the environmental factors responsible for its <br /> development.It has characteristic soils that have developed overtime;a characteristic <br /> hydrology, particularly infiltration and runoff, that has developed overtime-, and a <br /> characteristic plant community(kind and amount of vegetation).The vegetation, soils, <br /> and hydrology are all interrelated. Each is influenced by the others and influences the <br /> development of the others. For example, the hydrology of the site is influenced by <br /> development of the soil and plant community. The plant community on an ecological <br /> site is typified by an association of species that differs from that of other ecological <br /> sites in the kind and/or proportion of species or in total production. Descriptions of <br /> ecological sites are provided in the Field Office Technical Guide,which is available in <br /> local offices of the Natural Resources Conservation Service. Descriptions of those <br /> displayed in this map and summary table may also be accessed through the Ecological <br /> Site Assessment tab in Web Soil Survey. <br /> 13 <br />
