The map unit descriptions, along with the <br /> maps, can 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 more <br /> major kinds of soil or miscellaneous areas. A map unit is identified and named <br /> according to the taxonomic classification of the dominant soils. Within a taxonomic <br /> class there are precisely defined limits for the properties of the soils.On the landscape, <br /> however,the soils are natural phenomena, and they have the characteristic variability <br /> of all natural phenomena. Thus, the range of some observed properties may extend <br /> beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic <br /> class rarely, if ever, can be mapped without including areas of other taxonomic <br /> classes. Consequently, every map unit is made up of the soils or miscellaneous areas <br /> for which it is named and some minor components that belong to taxonomic classes <br /> other than those of the major soils. <br /> Most minor soils have properties similar to those of the dominant soil or soils in the <br /> map unit, and thus they do not affect use and management. These are called <br /> noncontrasting, or similar, components. They may or may not be mentioned in a <br /> particular map unit description. Other minor components, however, have properties <br /> and behavioral characteristics divergent enough to affect use or to require different <br /> management.These are called contrasting,or dissimilar,components.They generally <br /> are in small areas and could not be mapped separately because of the scale used. <br /> Some small areas of strongly contrasting soils or miscellaneous areas are identified <br /> 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 <br /> some characteristics of each. A few areas of minor components may not have been <br /> observed, and consequently they are not mentioned in the descriptions, especially <br /> where the pattern was so complex that it was impractical to make enough observations <br /> to identify all the soils and miscellaneous areas on the landscape. <br /> The presence of minor components in a map unit in no way diminishes the usefulness <br /> or accuracy of the data. The objective of mapping is not to delineate pure taxonomic <br /> classes but rather to separate the landscape into landforms or landform segments that <br /> 10 <br />
