Fellow radiators:

To Find Your Soil's Electric Conductivity

1) Go to: http://websoilsurvey.nrcs.usda.gov/app

2) Click on the big green button, "Start WSS".
. . .

This might be fun to do, but it probably doesn't really tell you your
soil's conductivity, which can vary a great deal from lot to lot and even
within a yard. And if it does, it's likely to be only the surface
conductivity. The skin depth for average soil is around 12 - 15 feet over
the HF range, so substantial current flows to that depth and below.
Typical soils are stratified, with potentially very different
conductivities at different depths.

So, after going through this exercise, you have a number. But that number
is of no real use.
