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,ordissimilar,components.They generally <br /> are in small areas and could not be mapped separately because of the scale used. <br /> 10 <br />
