Thanks to that may be affected mainly some parts of plants root systems, depending on the variability of electrical soil resistivity and underground layers, once again often relatively accurately in a circle.
Shukrani kwa Hiyo inaweza kuwa walioathirika Hasa baadhi ya maeneo ya mifumo ya mizizi ya mimea, kwa kutegemea tofauti za umeme Resistivity na tabaka ya chini ya ardhi udongo, kwa mara nyingine tena Relativt Mara nyingi usahihi katika mduara.
