An EcoFarmers Discovery Chapter 10: ScienceWelcome to An EcoFarmer's Discovery: The Companion Podcast, where every Friday we dive deep into one chapter of Ewan Campbell's journey.You're invited to read along – get the audiobook via Spotify (search An EcoFarmer's Discovery) or grab it on Kindle – and explore each chapter with us as we unpack the stories, ideas, and principles of regenerative farming. A new episode drops each Friday, covering 26 chapters across 26 weeks.

In This Episode:

Chapter 10 dives into the “simple” observations that led Ewan to uncover one of the biggest missing pieces in modern farming: soil is electrically driven. By revisiting school science, comparing reactivity charts, and talking with engineers, Ewan realised why minerals move the way they do, why plants absorb nutrients in different ratios than the soil holds, and why water-soluble fertilisers often create more problems than they solve.

From potassium corrosion to aluminium toxicity, cation exchange capacity, humus, and seasonal electrical switches inside trees, this chapter exposes the hidden electrical currents that shape soil health, plant growth, animal performance, and even the weeds that appear on your farm. Once you understand the electrical language of nature, the whole system starts making sense.

We explore:
• Why nutrients flow through plants electrically, not by solubility
• How water-soluble fertilisers trigger animal health issues
• The real meaning of CEC and why humus transforms soil capacity
• How electricity reveals toxicity, mineral imbalance & soil weakness
• What poplar trees, Redwood giants & solar-charged greenhouses teach us about natural electrical flow

Packed with humour, clarity, and practical insights, this episode shows why understanding electricity in the soil changes everything about how we farm.
