Mal,
I have to disagree with that (at least at my location).
In 1998 (on 137kHz) I started with about 20 radials (15 to 50m long)
on the ground. After replacing this by 5 radials (15 to 35m long)
about 10cm in the ground and with a 2m earth stake at each end ground
loss was reduced by 30%.
At my location the antenna is surrounded by many (100's) trees.
Maybe the situation is different in the open.

A couple of elevated insulated radials will out perform dozens of
buried radials, in fact 1 radial is vy effective, even insulated
radials lying above ground are also efficient.
I use 2 insulated 1/4 wave elevated radials on 500 khz and several
lying on the ground for 137 khz.
Using a loading coil in an elevated position on a vertical helps but
remember twice as many turns are required as opposed to base
loading hence more resistance, you might not be gaining as much
advantage as you think.
