Preliminary calculations indicate that the number will
be somewhere around 1000 pF. Pretty low.

That's if the ground is a pretty conductive surface, e.g. wet ground.
I'm guessing it would look like an air capacitor in series with a
leaky capacitor to an effectively zero potential surface somewhere
below the actual surface.
