You might look at your local soil surveys for better information, or contact
your local NRCS office.

I use the online Web Soil Survey.
http://websoilsurvey.nrcs.usda.gov/app/HomePage.htm

Once you select your area of interest and your soil type(s), you can
navigate to 'Soil Properties and Qualities' and then to 'Soil Chemical
Properties" and find Electrical Conductivity 'EC'.  It is listed as
millimhos per centimeter (same as millisiemens per centimeter if you
prefer).  You can look around at EC for your near and far fields and
hopefully have something of greater confidence than the FCC map.
