Commenting mostly as a placeholder so I can re-read this tomorrow morning. Also, this has been studied before, so there must be more studies out there…
Sounds like HN comments are pointing out some things that came to my mind:
Do the electrodes actually increase ion availability instead of purely stimulating growth based on an electrical field?
The open and closed circuits show about the same results in the study. That suggests current is not as important as voltage. (Voltage should be the same across the soil and the 100k resistor in the closed circuit test. Current is divided across those two in respect to their resistance.)
Which is more important: The capacitance across the anode and the cathode or the current flow through the soil? (I think they tested with frequency modulation? I can’t remember exactly.)
Enough notes. I’ll read through this again later. Goodnight!
