Your ground sounds like what I have. Clay with a "perched water table".
Only the clay here goes down 40 feet. Also, we have "cemented hard pan"
a few feet down. It is pretty much water tight. It sounds like you
might have that as well. Absolutely fantastic for RF. Very high
conductivity. Good for RF, lousy for growing stuff, except rice.
Can be improved for agriculture by deep plowing known as "ripping".
At this QTH, fewer radials are needed vs "normal" ground.

I am wondering about nr of radials to run.I understand that over water you sometimes
hurt things by adding radials over water…
At our new qth (3 yrs) I am finallyn putting up the vertical phased antennas for 80 meters.We live in an
area that has clay down abt a foor to 6 inchs below.Our water from ¼ in rain stays around for
days.then the ground is moist for abt a week.We dug a trash burn pit abt 6 mos ago.Abt 6 ft deep by 10
ft…It is full of water..Our last rain was 4 sdays ago…it’s not draining well due to
the clay.Is this considered a good ground? Are radials a good idea ?thanks,john w5jmw
