In this episode, Stephen and Ewan unpack the controversy surrounding a proposed $3 billion lignite-to-fertiliser plant in Southland, New Zealand, and ask a bigger question: why are we investing billions into synthetic nitrogen production when healthy soils already produce nitrogen naturally? What begins as a discussion around fertiliser security and global supply chains quickly becomes a deep dive into soil biology, carbon, trace minerals, and the hidden systems that drive productive farming.

Through the EFA lens, the conversation explores how rebuilding soil biology through trace minerals, carbon growth, and biological function can reduce fertiliser dependence while improving profitability, animal health, environmental outcomes, and food quality. The episode challenges modern agriculture’s reliance on synthetic inputs and argues that many farmers may already have the solution beneath their feet.

We discuss:• Why healthy soil biology naturally fixes nitrogen• The difference between synthetic and biologically fixed nitrogen• How trace minerals influence productivity and animal health• Why increasing soil carbon improves profitability and resilience• How farmers can reduce dependency through better soil management
