In this episode, Stephen and Ewan are joined by Jimmy, a lifelong West Coast coal mining expert, to explore the surprising connections between geology, mining, soil health, and modern agriculture.

What begins as a conversation about coal quickly expands into the history of New Zealand's geology, the science behind different coal types, mine rehabilitation, and how mining by-products are helping improve soil function and farm productivity.

Drawing on decades of experience in the mining industry, Jimmy shares insights into how coal is formed, processed, and used far beyond energy production, while also challenging common perceptions around environmental impact, land restoration, and the future of New Zealand's mineral resources.

Through the EFA lens, this episode examines how overlooked natural resources, practical problem-solving, and independent thinking can create opportunities for both farming and industry.

We discuss:
• How coal is formed and why different coal types have different uses
• Mine rehabilitation and restoring land back to productive use
• The surprising role of coal by-products in improving soil health
• Clean coal, energy efficiency, and common misconceptions about mining
• Why soluble silica and coal humates are becoming valuable farm inputs
• The future of New Zealand's mining industry and primary sector
• What farming and mining can learn from each other

In this episode, Stephen and Ewan are joined by Robin Claire, host of Cultivated Audio, for a fascinating conversation exploring soil health, regenerative agriculture, and the hidden forces shaping the future of farming.

What begins as a discussion around farming systems and mineral balancing expands into a deeper exploration of soil biology, electrical conductivity, microbial life, livestock health, and the complex relationships connecting soil, plants, animals, and people.

Drawing on decades of hands-on farming experience, Ewan shares the observations and discoveries that led him to investigate the electrical properties of soil and how minerals, biology, and natural systems work together to drive productivity, resilience, and ecosystem health.

Through the EFA lens, this episode challenges conventional agricultural thinking and highlights the importance of observation, curiosity, and farmer-led innovation in building healthier farms and food systems.

We discuss:
• The hidden electrical activity within healthy soils
• How minerals influence plant, animal, and human health
• The role of cyanobacteria, microbes, and biology in regenerative farming
• Why observation and on-farm experimentation matter
• Building resilient farming systems that work with nature

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

In this episode, Stephen and Ewan explore the forces shaping modern agriculture and ask a challenging question: are farmers really in control of their own industry?
From farm plans and environmental compliance to organic markets, profitability, carbon, and industry influence, the conversation examines how farmers can use testing, observation, and real-world results to make better decisions for their businesses and their land.
Drawing on decades of farming experience, Ewan argues that healthy soils, lower inputs, and farmer-led innovation are creating opportunities that many conventional systems continue to overlook.
Through the EFA lens, this episode challenges accepted narratives around farming, regulation, productivity, and sustainability while highlighting the importance of independent thinking and measurable outcomes.

We discuss:• Who really influences the direction of modern agriculture• Why testing and measurable outcomes matter more than assumptions• The profitability of organic and low-input farming systems• Farm plans, regulation, and farmer autonomy• Building resilient businesses through independent thinking and innovation

In this episode, Stephen and Ewan explore one of the most overlooked yet important drivers of soil health: cyanobacteria.

What starts as a discussion around regenerative farming, cover crops, and soil carbon quickly expands into a deep dive on soil biology, nutrient cycling, trace minerals, plant health, animal health, and the hidden processes that build productive farming systems from the ground up.

Drawing on decades of on-farm observation and testing, Ewan explains why cyanobacteria may be the foundation of healthy soils, how they contribute to carbon sequestration, nutrient availability, and biological function, and why many current farming practices may be working against them.

Through the EFA lens, this episode challenges conventional approaches to soil management and highlights the importance of understanding biological systems before reaching for costly inputs and interventions.

We discuss:• Why cyanobacteria are the foundation of healthy soil ecosystems• The relationship between soil biology, carbon, and nutrient cycling• Cover crops, regenerative farming, and what's often being overlooked• How trace minerals influence plant, animal, and soil health• Building productive farming systems by fixing the soil first
