Sometimes may occur a situation, when there is a complete discharge conducted to the ground by some at that location present an artificial or natural lightning rod (a tree, HV pole), but still underground occur electrochemical and thermal (physical and thermochemical) changes in soil and current flowing through plant roots, which over time may show changes in their growth.
Wakati mwingine hali inaweza kutokea, Wakati kuna kutokwa kamili umefanywa chini na mahali baadhi Kwamba katika fimbo ya sasa bandia au asili umeme (mti, HV shamba), Lakini bado kutokea chini ya ardhi electrochemical na mafuta mabadiliko (kimwili na thermochemical) katika udongo na sasa inapita njia ya mizizi ya mimea, ambayo baada ya muda inaweza kuonyesha mabadiliko katika ukuaji wao.
