<br />Map Unit Descriptions
<br />The map units delineated on the detailed soil maps in a soil survey represent the
<br />soils or miscellaneous areas in the survey area. The map unit descriptions, along
<br />with the 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
<br />landscape, however, the soils are natural phenomena, and they have the
<br />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
<br />including areas of other taxonomic classes. Consequently, every map unit is made
<br />up of the soils or miscellaneous areas for which it is named and some minor
<br />components that belong to taxonomic classes 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
