However, once you've got all those wires laid into the soil, some
breaks don't actually change the RF properties very much. What
you're really doing is effectively improving the soil conductivity
(especially for currents flowing in a radial direction), more than
creating an independent ground screen. Mind you, dragging a big
multi-gang plow across the radial field is probably not the best idea.
