The detineotion of such segments <br />on the map provides sufTdent infomratim? for the development of resource plans. If <br />intensive use of small areas is pruned, however, o to investigation is needed to <br />define and locate the soils and miscellieneous areas- <br />An identifying symbol precedes the rasp unit name in the map unit descriptions. Each <br />desorption includes general facts about the unit and gives important soil properties <br />and qualities. <br />Sills that have profiles that are almost alike make up a sod series. Except for <br />diNe ences in texture of the surface layer all the sorts of a series have major horizons <br />that are similar in composi iom thickness, and arrangement. <br />Soft of one series can Mw in texture of the surface layer, slope. stoniness, salinity, <br />degree of erosion. and other c haracxerMcs that n M; r I their use. On the basis of such <br />differences, a soil series is d'midedmtu sod phases Most of the areas shown on the <br />detailed soil maps are phases of soil series. The name of a soil phase commonly <br />indicates a feature that affects use or management. For example, Alpha sift loam, 0 <br />to 2 percent slopes, is a phase of the Alpha series. <br />Some map units are made up of two or more major soils or miscellaneous areas. <br />These map units are complexes, dons, or urdifIlerereated groups. <br />A complex consists of two or more sods or misceNwomm areas in such an intricate <br />pattern or in such small areas that they cannot be shown separately on the maps. The <br />Pattern and proportion of the soils or miscellaneous areas are somewhat similar in all <br />areas. Alpha-t3eta complex, 0 to 6 percent slopes, is an example. <br />An essocaisfan is made up of two or more geographically associated soils or <br />miscellaneous areas that are shown as one unit an the maps- Because of present or <br />anticipated uses of Ore map units in the survey area, it was not eorWdered practical <br />or necessary to map the soils or miseel areas stately. The pattern and <br />relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha- <br />Beta association, 0 to 2 percent slopes, is an example. <br />An unCfd&M loafed group is made up of two or more soils or miscellaneous areas that <br />could be mapped individually but we ripped as one unit because similar <br />interpretations can be made for use and managemert The pattern and proportion of <br />the soils or miscellaneous areas in a mapped area are not uniform. An area can be <br />made up of only one of the major sods or miscellaneous antes, or it can be made up <br />of all of them. Alpha and Beta sow, 0 to 2 percent slopes, is an example. <br />Some uaveys include mmepenecc?s areas. Such areas have liter or no soil material <br />and support tilde or no vegetation. Rods outcrop is an example. <br />11
