Where I live, the soil is 100% clay and the RF conductivity is

Vastly better for growing anything, even weeds. But the RF
conductivity is considerable lower.
A casual observer sightseeing would have no idea of this
change in soil.
Here's a link to the ground conductivity contour map from FCC Regs for
the AM broadcast band. http://k9yc.com/FCC-GroundMap.zip
