There are already sufficients ions in the soil to conduct well.
- Scoundreller 8y agoThe question is, does it conduct well enough? And that depends on soil type and moisture level. When it doesn't, even 0.1% salt in the soil moisture has 1/10th the resistance: https://www.newark.com/pdfs/techarticles/megger/Tech_Tips.pdf https://www.newark.com/pdfs/techarticles/megger/Tech_Tips.pd... (top-right). Over time, whatever ions are in the soil will get washed away, so you need to keep re-adding, even if you started off with ion rich soil (e.g. from backfilling).
