Is there some way you could lay a half wave dipole on the ground and measure the resonant frequency and radiation resistance vs the known free space values, and convert this to ground conductance and permittivity? Perhaps model it in some version of NEC and play with the ground constants until the modeling program agreed with the measured impedance and frequency?
