The map unit descriptions, along with the maps, can <br /> be used to determine the composition and properties of a unit. <br /> A map unit delineation on a soil map represents an area dominated by one or moremajor kinds of <br /> soil or miscellaneous areas.A map unit is identified and named according to the taxonomic <br /> classification of the dominant soils. Within a taxonomic class there are precisely defined limits for <br /> the properties of the soils. On the landscape, however, the soils are natural phenomena,and <br /> they have the 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 including areas <br /> of other taxonomic classes. Consequently, every map unit is madeup of the soils or <br /> miscellaneous areas for which it is named and some minor components that belong to taxonomic <br /> classes other than those of the major soils. <br /> Most minor soils have properties similar to those of the dominant soil or soils in themap unit, and <br /> thus they do not affect use and management. These are called non-contrasting, or similar, <br /> components.They may or may not be mentioned in a particular map unit description.Other <br /> minor components, however, have propertiesand behavioral characteristics divergent enough to <br /> affect use or to require differentmanagement.These are called contrasting, or dissimilar, <br /> components.They generally are in small areas and could not be mapped separately because of <br /> the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are <br /> identified by a special symbol on the maps. If included in the database for a given area, the <br /> contrasting minor components are identified in the map unit descriptions along with some <br /> characteristics of each. A few areas of minor components may not have been observed, and <br /> consequently they are not mentioned in the descriptions, especially where the pattern was so <br /> complex that it was impractical to make enough observations to identify all the soils and <br /> miscellaneous areas on the landscape. <br /> The presence of minor components in a map unit in no way diminishes the usefulness or <br /> accuracy of the data.The objective of mapping is not to delineatepure taxonomic classes but <br /> rather to separate the landscape into landforms or <br /> 10 <br />
