The EcoFarm Aotearoa Podcast – Book Companion Series.
This episode covers Chapter 19 and dives into one of the most controversial and intriguing concepts in regenerative agriculture: biological transmutation. What sounds like alchemy becomes a practical exploration of how soil biology can transform elements, balance nutrients, and supply what plants and animals need without constant external inputs.

From kiwifruit orchards producing potassium without applications, to chooks laying hard shells without added calcium, Ewan and Steve challenge chemistry-only thinking and unpack the role fungi, bacteria, and even electrical stimulation play in nutrient cycling. At its heart, this chapter is about restoring trust in biology and questioning the systems that shut it down.

We explore:• What biological transmutation is and how it differs from conventional chemistry
• Orchard lessons from potassium cycling and the PSA wake-up call
• Bioremediation: how fungi and microbes break down toxins once thought permanent
• Why herbicides disrupt nutrient creation at its source
• How farmers can regain independence by working with biology, not against it

This episode is a reminder that nature already knows how to build, balance, and repair if we stop interfering long enough to let it work.
