der normal management, but wh'ait does periodically change is technology and our ability to compare various characteristices of soils (color, texture, depth, i.e.) across county and state lines. ;
Once a soil has been identified' and named, it must, for all practical purposes, be the same throughout’ the land. For example, a soil mhfrr ping unit often gets its name frdm' the location where it was first identi-’ fied, such as Culpeper clay loam'or Orange silt loam. Once this occurs, this becomes the mold for all otH^r Culpeper or Orange soils, and if1 a soil has been improperly mapped, it. now must be changed.
This is where the problem occhVs with very old surveys. Surveys published primarily for agricultural usesare not as useful to units of government, developers, and planners when it comes to landuse planning1, landfills, housing sites and prisons'.:" •
This forces the Soil ConservationService (SCS) to revisit the fields* torefine or update these old obsolete surveys. This also requires changing' the name of some soils that you have come to know, and even changing* few of the interpretations. - . For example, the existing Culpeper survey maps will show Crt>ton, but we no longer recognize this mapping unit here. Croton is now called Worsham. We generally say reports that are over 15 years bid may have questionable information. 'h , I have had several farmers isk why don’t we just change it? This can not be done, because if a change is made one place, it must 'be changed all over. ,M ,;
