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.
