Earth acts more like a conductor, than a dielectric.
Actual earth is sometimes used as a current return for utility power to rural districts, to save on wire (they run a single power wire out to the farm and the other "wire" is the ground).
In oil-well logging the sponteneous potential between the surface and the position 1000s of feet underground in the well is always measured. If earth wasn't a conductor, that couldn't be done very well.

It all depends on what kind of soil you have and what the moisture content is. Dry sandy soil will be a lousy conductor while soil which is loaded with organic material and water wil be better.
