AM ground systems use a straight plow mounted on a tractor with the wire fed
out the back through a small pipe.  I's imagine a rototiller could be
modified with a narrow saw-type blade to go through roots and the like, and
to push small rocks aside.  Use a blade with a small pipe on the back to
force the wire to the bottom of the slot.  Probably could get half a foot or
so down easily.

A while back I inquired if anyone had ever simply pulled a wire out into a
shallow lake.  Fresh water has low conductivity, so that might work well.  I
should scare up a rowboat.  There is a nice long shallow pond not far from
me, and I could get a couple thousand feet of wire in that without any
trouble.  Worth a shot, when I get some time.  I did just win about 900' of
#14 wire on eBay.

Some years ago I had access to an old buried (long disconnected) feed for
some lighting.  It was maybe 50' and 18-24" underground.  It was *very*
directional on the high end of the band.  Quasi local WPEP-1570 was
inaudible, and a station in western MA that was on at that time was dominant
mid-day.  I think the soil slowed the velocity of propagation down
considerably, and therefore the directionality.
