| Cultivation and Cropping: The Mistake That Costs Farmers Thousands | 16 sept. 2026 | 00:49:36 | |
Winter cropping can be expensive, risky and essential for getting livestock through the colder months. But what if the way we prepare a cropping paddock is actually setting it up to fail? In this episode, Ewan and the team dig into the thinking behind winter crops, soil preparation, carbon, nitrogen and the role of soil biology. They explore the idea of the “fake boost”, where spraying and disturbing the soil can create a rapid burst of growth, while potentially leaving the paddock depleted afterwards. The conversation looks at how farmers can approach cropping with more preparation, better timing and a focus on building the soil before the crop goes in. They also discuss cultivation, fallow periods, weeds, cyanobacteria, crop economics and why a cropping paddock doesn't have to be treated as a sacrifice. In this episode:

| More Farming Questions Answered: Nitrogen, Fungi & More | 21 août 2026 | 00:14:09 | |
The questions keep coming! In Part 2 of our farming Q&A, we continue answering your comments, challenging conventional thinking and digging deeper into some of the biggest conversations around modern agriculture. In this episode: In this episode of EcoFarm Aotearoa, the discussion turns to synthetic nitrogen, soil carbon, fungi, soil biology and the importance of questioning the systems we've come to rely on. We explore the argument that soil has its own natural nitrogen system, and ask what happens when we replace those natural processes with synthetic inputs. We also revisit the story behind the fungal "Control Alt Delete" experiment, including the use of different fungal species and the surprising changes observed in the soil and livestock. The conversation explores the different roles fungi can play in soil biology and their relationship with other microorganisms such as cyanobacteria. But ultimately, this episode comes back to a bigger question: how do we make better decisions on farm? Rather than simply accepting what we're told, Ewan and the team discuss the importance of asking questions, running trials, observing the results and staying open to new ideas. From unexpected solutions to long-term consequences of farming practices, this is another wide-ranging Q&A exploring how we can think differently about agriculture.
If you enjoyed Part 1, there's plenty more to dig into here. And as always, the goal isn't to tell you what to think, it's to encourage better questions, better observations and better conversations around farming.

An EcoFarmer’s Discovery Chapter 28: Reality Check Thank you for listening to An EcoFarmer’s Discovery: The Companion Podcast, this is the final Ewan Campbell’s journey throughout the book. In this episode, Stephen Brunton and Ewan unpack the final chapter of the book, Chapter 28: Reality Check, bringing the series to a grounded and thought-provoking close. This conversation steps back from theory and dives into the practical realities of farming, challenging listeners to rethink assumptions, question systems, and take ownership of their results. Ewan emphasises the critical importance of benchmarking as a starting point for any farming system, highlighting how data collection across soil, water, and herbage provides not only a pathway for improvement, but also protection against misinformation, poor advice, and bureaucratic pressure. Without a clear baseline, progress becomes impossible to measure, and claims—whether from farmers or regulators—lack real substance. The discussion explores the barriers to adopting biological and regenerative practices, with a strong focus on mindset, education, and the willingness to confront uncomfortable truths. Ewan shares insights into how small, consistent changes—guided by real data—can lead to measurable improvements in productivity, environmental outcomes, and farm resilience over time. A key theme throughout the episode is the importance of working with nature rather than against it. From protecting soil biology to reducing reliance on sprays and external inputs, Ewan reinforces that long-term success comes from understanding natural systems and allowing them to function as intended. The episode also touches on the broader challenges facing modern agriculture, including industry narratives, policy pressures, and the influence of outdated thinking. Through honest reflections and practical examples, this final chapter encourages farmers to think independently, embrace learning, and move forward with confidence. At its core, this is a “reality check” not just for farming systems, but for the way we think about progress, responsibility, and success in agriculture. It’s a powerful conclusion that ties together the entire journey, leaving listeners with both clarity and motivation for what comes next. We discuss:• Why benchmarking and data collection are essential before making changes• How soil, water, and herbage testing guide better decision-making• The role of data in protecting farmers from poor advice and bureaucracy• Common mental barriers to adopting regenerative practices• Why protecting soil biology is key to long-term farm success• The importance of working with nature instead of against it• How independent thinking can drive better outcomes on-farm Powered by: EcoFarm Aotearoa – www.efa.nzLink to our free ebook!https://www.ecofarmaotearoa.nz/download-our-ebook/Listen to An EcoFarmer’s Discovery: https://open.spotify.com/show/3wIgUUghlsKIje76E5tjBA?si=b4aa009579a34ac1 | |||
| How Farmers Are Losing $21,000/ha Without Realising It | 15 avr. 2026 | 00:29:31 | |
In this episode, Stephen and Ewan unpack the growing tension between water quality, farm profitability, and the long-standing reliance on synthetic inputs. What starts as a conversation about environmental pressure quickly reveals a deeper issue, farm systems that are quietly depleting their own soil capital over time. Through real on-farm numbers and practical examples, Ewan breaks down how decades of nitrogen use have led to a steady loss of organic carbon, reducing the soil’s natural ability to hold nutrients and water. The result? Farmers aren’t just buying fertiliser, they’re replacing what their soil used to provide for free. Looking through the EFA lens, the discussion shifts toward rebuilding soil function through biology, carbon, and mineral balance. By increasing organic matter and restoring natural nutrient cycles, farmers can reduce input costs, improve production, and take back control of their systems, while also addressing environmental concerns like water quality. This episode highlights a powerful opportunity: by changing the system, farmers can move from constantly spending on inputs to actually rebuilding long-term value in their soil. We discuss:• The link between water quality issues and farm profitability• How decades of nitrogen use have depleted soil carbon• The hidden financial loss of declining soil organic matter• Why synthetic fertiliser replaces, rather than builds, fertility• The impact of low dry matter and “watery” feed on production Our FREE E-Book!https://www.ecofarmaotearoa.nz/download-our-ebook/Listen To An EcoFarmer’s Discovery:https://open.spotify.com/show/3wIgUUghlsKIje76E5tjBA?si=b4aa009579a34ac1 | |||

An EcoFarmer’s Discovery Chapter 25: Fits Together Welcome to An EcoFarmer’s Discovery: The Companion Podcast, where every Friday we dive deep into one chapter of Ewan Campbell’s journey. In this episode, Stephen Brunton and Ewan unpack Chapter 25: Fits Together, exploring the powerful idea that true abundance in farming comes from understanding and working with the natural systems already in place. The conversation centres around a key principle: when the right conditions are created, nature does the heavy lifting. From extraordinary examples of naturally fertile soils to the role of biology, minerals, and even electromagnetic forces, this episode reveals how all the pieces of the puzzle connect to unlock productivity and resilience on farm. Ewan shares insights from decades of experience, explaining how soil health is built through observation, testing, and incremental adjustments, not quick fixes. From identifying limiting factors like trace element deficiencies, to reintroducing biology and allowing systems to function as intended, farmers can begin to see dramatic improvements in pasture performance, animal health, and long-term sustainability. The discussion also dives into the deeper connections between soil, plant, animal, and human health, highlighting how factors like environment, nutrition, and even electrical signals influence outcomes in ways we’re only beginning to understand. At its core, this chapter is about stepping back, seeing the bigger picture, and realising that everything on the farm is interconnected. We discuss:• What “abundance” really looks like in natural systems• How soil minerals, biology, and energy systems work together• The importance of testing, observation, and adapting over time• How environmental signals influence plant and animal performance• Why many modern practices limit true soil potential• The value of learning from nature, not fighting it Hosted by: Stephen Brunton & Ewan CampbellPowered by: EcoFarm Aotearoa – www.efa.nzLink to our free ebook!https://www.ecofarmaotearoa.nz/download-our-ebook/Listen to An EcoFarmer’s Discovery: https://open.spotify.com/show/3wIgUUghlsKIje76E5tjBA?si=b4aa009579a34ac1 | |||
| What Most Farmers Get Wrong About Regenerative Agriculture | 25 mars 2026 | 00:09:51 | |
In this episode, we hear directly from a fourth-generation farmer who is transitioning away from conventional, chemical-based agriculture and into a regenerative system, while building a premium food brand alongside it. After years of dealing with rising input costs, fertiliser reliance, and commodity pricing pressure, he began questioning the system. What followed was a shift toward regenerative principles: covering the soil, integrating livestock, eliminating synthetic inputs, and working with natural biological processes rather than against them. But this journey goes beyond farming practices. By producing eggs, yoghurt, and value-added products, and selling directly through a growing retail network, he’s proving that regenerative agriculture isn’t just about improving soil health… it’s also about creating a more profitable and resilient business model.

An EcoFarmer’s Discovery Chapter 24: A Ray of Light Welcome to An EcoFarmer’s Discovery: The Companion Podcast, where every Friday we dive deep into one chapter of Ewan Campbell’s journey. In this episode, Stephen Brunton and Ewan unpack Chapter 24: A Ray of Light, reflecting on the power of observation, the intelligence of nature, and the breakthroughs that come when farmers begin to trust what they see. The conversation centres around a core idea: nature already has the answers — if we’re willing to observe, question, and step outside conventional thinking. From surprising on-farm discoveries like the role of fungi and even “magic mushrooms” in animal health, to the rapid recovery of pasture through biological processes, this episode highlights the turning point where challenges begin to reveal solutions. Ewan shares practical insights from years of trial and error, showing how once hidden residues, soil imbalances, and biological disruptions can be addressed through natural systems. As these barriers are removed, farmers begin to see rapid improvements in pasture growth, animal health, and overall farm resilience — the “ray of light” that signals real progress. The discussion also explores the mindset shift required in modern farming — moving away from reliance on external advice and toward confidence in personal observation, testing, and understanding. From field trials to farmer-led discoveries, this episode reinforces that some of the most powerful insights come directly from the land itself.

| A Farmer Flew From Wales to Visit…What He Learned Could Transform His Farm | 18 mars 2026 | 00:47:30 | |
In this episode, Stephen and Ewan are joined by a visiting farmer from Wales, offering a rare and powerful comparison between farming systems on opposite sides of the world. What starts as a simple farm visit quickly becomes something much bigger, as shared challenges, rising costs, and declining soil health reveal just how universal the pressures on modern farming have become. Through open conversation, the episode highlights how different climates, systems, and markets still lead to many of the same problems, from weed pressure and input reliance to animal health and profitability. But it also shows something more important: the opportunity for change. As the Welsh farmer explores the EFA approach firsthand, it sparks a shift in thinking, one that could completely reshape the future of his farm. Ewan brings valuable insight from the EFA perspective, breaking down how soil biology, mineral balance, and system-wide thinking can reduce costs, improve animal performance, and rebuild resilience. From milk quality and nutrient cycling to weeds as indicators of imbalance, the discussion offers practical lessons that extend far beyond one farm, showing how these principles can be applied anywhere in the world. Along the way, the conversation challenges conventional approaches to fertiliser use, chemical inputs, and pasture management, revealing how many common farming struggles are symptoms of deeper issues in the soil. We discuss:• What happens when farmers from opposite sides of the world compare systems• Why many farming challenges are universal, regardless of location• How the EFA approach can reduce costs and improve resilience• The link between soil health, animal performance, and product quality• Why weeds can signal deeper imbalances in the soil• The hidden impact of fertilisers and chemicals on long-term farm health• How shifting mindset can completely transform a farming system Our FREE E-Book!https://www.ecofarmaotearoa.nz/download-our-ebook/ Listen To An EcoFarmer’s Discovery:https://open.spotify.com/show/3wIgUUghlsKIje76E5tjBA?si=b4aa009579a34ac1 | |||
| Chapter 23: Forgotten Biology | An EcoFarmers Discovery Audiobook Companion Podcast | 13 mars 2026 | 00:25:02 | |
An EcoFarmer’s Discovery Chapter 23 Forgotten Biology Welcome to An EcoFarmer’s Discovery: The Companion Podcast, where every Friday we dive into one chapter of Ewan Campbell’s journey. In this episode, Stephen and Ewan explore Chapter 23: Forgotten Biology, focusing on the overlooked role of cyanobacteria in soil health and agricultural systems. Often misunderstood as toxic “blue-green algae,” cyanobacteria are usually associated with polluted waterways and animal poisoning events. But the discussion reveals a very different side to these ancient organisms, highlighting their powerful role in nutrient cycling, soil biology, and ecosystem regeneration. Ewan explains how certain marine-derived cyanobacteria can function within soil environments, supporting biological processes that modern agriculture has largely ignored. The conversation challenges common perceptions and explores why many soils today may not be biologically balanced enough for these organisms to thrive. By looking deeper into the relationship between ocean biology and land systems, the episode raises an important question: what critical parts of soil ecology have been forgotten along the way? We discuss:• Why cyanobacteria are often misunderstood in agriculture• The difference between toxic blooms and beneficial soil species• How ocean-based biology can function in soil systems• Why modern soils may struggle to support these organisms• The potential role of cyanobacteria in regenerative farming Hosted by: Stephen Brunton & Ewan Campbell Powered by: EcoFarm Aotearoa – www.efa.nz | |||
| Paradigm Busting: The Truth About Regenerative Farming, Part 2 | 11 mars 2026 | 01:00:40 | |
In this episode, Stephen and Ewan explore one of the most powerful forces shaping modern farming: mindset. While regenerative agriculture is often framed around practices like rotational grazing or reducing inputs, the real shift begins with something deeper, the willingness to question long-held beliefs about how farming “should” work. The conversation unpacks how healthy soils drive resilient farms, explaining why livestock, microbes, minerals, and plant diversity must function as a connected system. From nutrient cycling and parasite resistance to drought resilience and carbon storage, the episode shows how regenerative outcomes emerge when soil biology is supported rather than forced. Along the way, they challenge common assumptions about weeds, fertilisers, cropping systems, and animal health, revealing how many of agriculture’s biggest problems are actually symptoms of deeper imbalances in soil chemistry and biology. We discuss:• Why livestock are essential for nutrient cycling in regenerative systems• The role of soil biology, fungi, and microbes in building humus• How mineral balance influences plant health and parasite resistance• Why weeds can be signals of missing nutrients in the soil• The difference between organic farming and regenerative outcome Our FREE E-Book!https://www.ecofarmaotearoa.nz/download-our-ebook/Listen To An EcoFarmer’s Discovery:https://open.spotify.com/show/3wIgUUghlsKIje76E5tjBA?si=b4aa009579a34ac1 | |||
| Chapter 22: Invisible Menace | An EcoFarmers Discovery Audiobook Companion Podcast | 06 mars 2026 | 00:50:40 | |
An EcoFarmer’s Discovery Chapter 22 Invisible Menace Welcome to An EcoFarmer’s Discovery: The Companion Podcast, where every Friday we dive deep into one chapter of Ewan Campbell’s journey. In this episode, Stephen and Ewan unpack Chapter 22: An Invisible Menace, exploring the concept of vibrational residues and the unseen energetic imprints left behind by agricultural chemicals and electrical infrastructure. The conversation moves beyond chemistry alone, examining how soils that are rich in silica may act as memory systems, storing not just chemical residues but frequency imprints from past treatments. From hormone sprays like 2,4-D and legacy products such as DDT, to modern electrical systems, smart meters, and on-farm power infrastructure, this episode questions what remains long after laboratory tests say a paddock is “clean.” Ewan shares firsthand experiences from his own farm, including unexpected tree deformities, livestock behaviour changes, and the discovery that increasing soil electrical activity amplified historical residues. What followed was a deep exploration into remediation from fungal “control alt delete” systems and mycelial networks, to paramagnetic and volcanic rocks placed on fences and earth systems to mitigate electromagnetic interference. The discussion connects soil silica, electrical current, EMF, and biological function, drawing parallels between computers, memory storage, and living systems. Concepts such as homeopathy, radionics, resonance, and even quantum mechanics are examined through a practical farming lens, not as abstract theory, but as tools Ewan has tested in the field.

| Paradigm Busting: The Truth About Regenerative Farming, Part 1 | 04 mars 2026 | 00:46:22 | |
In this episode, Stephen and Ewan move beyond “math busting” and into something even deeper: paradigm busting. What if the biggest barrier to regenerative farming isn’t nitrogen rates or phosphate targets, but the mental models farmers have inherited for generations? From no-till myths to spray-first thinking, they unpack how industry narratives shape decisions long before a paddock is ever walked. The conversation challenges assumptions around cultivation, cover crops, soil disturbance, and diversity, revealing how some widely accepted “regenerative” practices may still be missing the biological foundation entirely. At the heart of the episode is a simple but confronting truth: systems regenerate when biology regenerates. And biology doesn’t respond to labels like conventional, organic, or regenerative, it responds to mineral balance, carbon pathways, electrical charge, and living roots.

| Chapter 21: The Dusts | An EcoFarmers Discovery Audiobook Companion Podcast | 27 févr. 2026 | 00:42:13 | |
The EcoFarm Aotearoa Podcast – Book Companion Series. In this episode, Stephen and Ewan explore the hidden role of tissue salts and electrical nutrition in soil, plant, animal, and human health. Challenging conventional ideas about how minerals actually function within biological systems. The conversation connects cellular processes, soil biology, and farm management through one central idea: true fertility is biologically created, not chemically applied. Rather than viewing nutrients as simply soluble inputs, this episode examines how minerals must be transformed through living systems to become electrically available and functional. From cyanobacteria and microbial activity to pasture growth and animal wellbeing, Stephen explains how soil biology creates the mineral “salts” that underpin resilience, productivity, and nutritional density. The discussion moves beyond fertiliser recipes to a systems-based understanding of farming, where observation, biological function, and mineral balance replace product-driven decision making. Along the way, the conversation links soil health with food quality, farm profitability, and the long-term consequences of relying on soluble inputs. We discuss: Using practical farm observations and cross-disciplinary thinking, this episode reframes agriculture as a living electrical system, where healthy soils create healthier plants, animals, and ultimately people. When farmers shift from chasing inputs to supporting biological function, complexity reduces and independence increases.

| The Math Ain’t Mathing: Nitrogen, Phosphate & Farming’s Biggest Blind Spots | 25 févr. 2026 | 00:46:19 | |
In this episode, Stephen and Ewan challenge some of farming’s most accepted assumptions and ask a simple question: what if the math isn’t mathing? From nitrogen targets to phosphate “maintenance” rates, they unpack how industry norms became unquestioned truths and why many of them don’t hold up under first-principles thinking. The conversation walks through real on-farm numbers, showing how excess nitrogen creates animal stress and runoff issues, and how phosphate applications often far exceed what actually leaves the farm. Rather than blaming cows or chasing production per hectare, this episode reframes the focus toward soil function, biological processes, and one metric that truly matters: profit per hectare. We discuss:• Why 4–5.5% nitrogen in pasture may be fundamentally flawed Using practical farm examples, the episode demonstrates how testing, measurement, and simple calculations can dismantle long-held assumptions. When farmers understand the source of nitrogen and phosphorus flows they can reduce pressure, improve resilience, and regain control from systems that profit off complexity and confusion.

| Chapter 20: Structure | An EcoFarmers Discovery Audiobook Companion Podcast | 20 févr. 2026 | 00:51:19 | |
The EcoFarm Aotearoa Podcast – Book Companion Series. In Chapter 20 of The EcoFarm Aotearoa Book Companion Series, we explore the idea of structure, from the soil beneath our feet to the spine in our bodies. What begins with a conversation about jaw alignment and Western Price quickly unfolds into a much deeper discussion about how mineral balance, nutrition, and physical structure are inseparable. Whether it is calves developing broader heads after changes in soil management or the visible shift in posture through functional dentistry, the message is clear. Structure reflects health. This episode moves between farm practice and personal experience, showing how addressing root causes rather than symptoms transforms outcomes. From soil tests and mineral corrections to foot alignment, spinal charts, and DNA sequencing, the common thread is foundation. When the base is right, resilience follows. When it is neglected, problems surface elsewhere. Farming, business, community, and human health all mirror the same principle.

| "Now its easy, just spread the fert and F*CK IT" - huge farming lifestyle improvements! | 18 févr. 2026 | 00:41:14 | |
In this episode, Stephen and Ewan sits down with Ross and Lance, who made a bold transition away from conventional inputs and into biological system thinking. What began with digging holes and finding no worms has evolved into a complete mindset shift, from chasing nitrogen and spraying weeds to rebuilding soil depth, animal health, and farm confidence. The conversation follows their two-and-a-half-year journey, including the tough first 12 months, the drop in pasture production, and the turning point when animal health rebounded and costs began to fall. From reducing nitrogen from 150 units to just 5, eliminating Roundup and routine drenching, and watching worm castings return, this episode explores what really happens when you move from feeding plants to feeding soil biology. We discuss:• Dropping nitrogen from 150 units to 5 and what happened next Using real on-farm examples, the discussion shows how shifting from a consumable input model to a soil-first biological system doesn’t just change pasture, it changes decision-making, confidence, and lifestyle. Rather than chasing symptoms with more product, the focus becomes removing limiting factors, stabilising biology, and building a system that strengthens year after year.

| The Missing Step in Regenerative Farming | 11 févr. 2026 | 00:55:40 | |
In this episode, Stephen and Ewan unpack what happens after soil health starts improving and why many farms hit a wall precisely when things should be working better. As regenerative systems begin to function, old habits, missing steps, and unseen limiting factors can quietly undo progress if the full process isn’t followed. The conversation walks through EcoFarm Aotearoa’s start-to-finish methodology, explaining why accuracy, system thinking, and education matter more than quick fixes. From GPS-based soil testing and biological sequencing to EMF interference and boundary effects, this episode reframes farming as a new operating system, one that must be learned, not assumed. We discuss:• Why soil success can create new problems if the process isn’t understood Using real farm examples, Ewan explains why powering up biology without addressing frequency, logistics, and process can amplify problems rather than solve them. Rather than chasing symptoms, the discussion focuses on removing guesswork, protecting gains, and building resilient systems that continue to improve year on year.

The EcoFarm Aotearoa Podcast – Book Companion Series.This episode covers Chapter 18 and dives into one of the most misunderstood and powerful forces in farming: fungi. What begins with a moment of curiosity (and a fair bit of trial, error, and “stupidity”) quickly turns into a profound rethinking of how soil, plants, animals, and humans are all connected through biological digestion and nutrient cycling.Ewan and Steve unpack the early observations that sparked the chapter — ragwort pulling out effortlessly, worm activity exploding, and soil structure transforming almost overnight. From there, the conversation follows Ewan’s hands-on experiments with fish, fungal brews, and species-specific inoculation, challenging mainstream compost tea theory and the idea that all microbes are interchangeable. Rather than importing generic biology, the focus shifts to understanding which fungi belong where, and why protein-focused pastures require entirely different fungal relationships than forests.We explore:• How fungal activity radically changed soil structure and weed behaviour• Why “one-size-fits-all” microbes don’t work in agriculture• Fish, fungi, and the biology behind smell, digestion, and neighbour complaints• Fruiting bodies, stress signals, and what mushrooms really indicate• Higher-order plants, weeds as indicators, and speeding up natural successionThis episode is about shifting from control to process and why real progress in farming depends on working with biology, not against it.Follow along.

The EcoFarm Aotearoa Podcast - Book Companion Series.This episode covers Chapter 17 and revisits the moment the story burst out of the courtroom and into the public eye — when 60 Minutes turned up, asked the questions the system wouldn’t, and changed the game.Ewan and Steve unpack what it was like meeting Melanie Reid and her producer with healthy skepticism (the good kind), then watching the investigation unfold as she worked through the court documents and kept texting variations of: “You’ve got to be kidding me.” Unlike the courtroom, someone was finally listening — and verifying.The conversation explores the pressure that followed the Commerce Commission decision, the machinery that kicks in when a system decides you’re a “target,” and the real-world fallout: reputational attacks, enforcement that felt more like bullying than justice, and the cost of simply refusing to fold.From there, the episode widens out into the bigger theme behind the chapter: when communities stop standing up for themselves, systems drift from practical, local problem-solving into corporate gatekeeping, process for process’ sake, and authority without accountability. Ewan also shares how this experience pushed him into studying the law — not for revenge, but to understand how it works and how ordinary people can actually use it.We also touch on the irony (and the dark humour) of supplying premium meat to the very circles connected to the prosecution — plus a wild side-story involving BBC Radio 4, international demand, and how quickly opportunity can get shut down by bureaucratic interference.We explore:• How 60 Minutes got involved — and why skepticism mattered• What Melanie’s investigation exposed that court process didn’t• The aftermath: public pressure, enforcement, and the cost of holding your ground• Why it was never about “does it work?” — but about legal traps and narrative control• Gatekeepers, corporatisation, and why communities feel less able to act• The mindset shift: learning from losses, standing up, and staying productiveThis episode is about what happens when scrutiny finally meets power — and why progress (in farming or law) often depends on people being willing to take a few hits and get back up again.Follow along.

Ewan reflects on the rise of Probitas, the backlash that followed its success, and the systems that move to shut down ideas that threaten entrenched interests. In This Episode:Ewan shares the personal and professional fallout of challenging the fertiliser industry and regulatory system, including court cases, media manipulation, fear-based enforcement, and the misuse of “false and misleading representation” laws. The conversation reveals how innovation, when it disrupts powerful industries, can trigger intimidation rather than investigation. This chapter explores how fear is used to control farmers, suppress discovery, and protect billion-dollar systems at the expense of soil health, food quality, and rural communities. From patents and expert witnesses to search warrants and media pressure, Ewan breaks down how the system operates and how farmers can begin to push back. We explore:

Read or listen along by searching An EcoFarmer’s Discovery on Spotify, or find the book on Audible and Kindle. Each episode unpacks the stories and principles behind regenerative farming, with 26 chapters released across 26 weeks. This episode covers Chapter 15 and explores the hidden structure of soil, aluminium toxicity, and why misunderstanding soil chemistry puts entire farming systems at risk. In This Episode Ewan explains why most farmers have never been taught what soil is actually made of, unpacking aluminosilicates, pH behaviour in volcanic soils, and how soluble aluminium quietly shuts down biology. The discussion introduces the importance of the SW07 soil test, why traditional fertiliser advice often makes problems worse, and how misreading soil data leads to escalating inputs and declining function. The conversation connects soil chemistry to plant expression, human health, and historical fertiliser use. From hieracium infestations and shiny aluminium-loving plants to phosphate binding, silicon lock-up, and calcium availability, this episode shows how toxicity, not deficiency, is often the real issue. We explore:• Why aluminium toxicity, not deficiency, shuts down soils • How soil tests like SW07 reveal hidden system failures This episode is about understanding structure over inputs, biology over chemistry, and why healthy soils depend on removing toxicity, not adding more product.

| Tissue Salts: Mineral Intelligence & Cell Function | 30 déc. 2025 | 00:58:51 | |
Tissue Salts: Mineral Intelligence & Cell Function The EcoFarm Aotearoa Podcast Modern farming often treats symptoms instead of causes. In this episode, Stephen and Ewan dig into the mineral foundations that sit beneath soil health, plant function, animal performance, and ultimately human health. Starting at the single cell, they explore how functional minerals, biology, and electrical processes work together to create resilient systems that actually pay off financially for farmers. The conversation moves from ancient science and tissue salts to modern soil testing, showing how cyanobacteria, microbes, and mineral organisation underpin productive land. Rather than adding more inputs, this episode focuses on creating the conditions that allow minerals to move, organise, and function correctly through the entire food chain. From soil conductivity and mineral lock-up, to animal symptoms, plant signalling, and the role of seawater chemistry, this episode connects the dots between soil, water, herbage, animals, and people. We discuss: • Why healthy soil must be biologically active and electrically conductive This episode is about understanding cause and effect, restoring mineral balance, and learning to work with natural systems rather than constantly reacting to problems. It is a deeper look at how reading the land properly leads to healthier farms and more sustainable outcomes.

An EcoFarmer’s Discovery Chapter 12: The Meat Producer Welcome 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 by searching An EcoFarmer’s Discovery, or grab it on Kindle, and explore each chapter with us as we unpack the stories, observations, and principles behind regenerative farming. A new episode drops every Friday, covering 26 chapters across 26 weeks. In This EpisodeThis episode focuses on the meat produced on Ewan’s farm, and what happens when animal health, soil function, and nutrition are aligned. Ewan and the team unpack how changes in soil biology, mineral balance, and feed quality translate directly into the quality of meat leaving the farm. Rather than chasing premiums or labels, the focus is on producing food that is clean, nutrient-dense, and honest, with nothing to hide. The conversation links soil testing, herbage testing, and animal observation back to real outcomes, including flavour, structure, shelf life, and consumer trust. It is a practical look at how farming systems show up at the end of the chain, on the plate. We explore:• How soil health influences animal health and meat quality • Why mineral balance and pasture diversity matter for livestock nutrition • What herbage and soil tests reveal about feed quality • The connection between clean systems and clean food • Why producing good meat starts long before the animal is finished This episode is about accountability, observation, and pride in producing food that reflects a well-functioning farm system from the soil up.

| Inside EcoFarm Aotearoa: Soil, Water & Herbage Testing | 24 déc. 2025 | 00:54:41 | |
Inside EcoFarm Aotearoa: Soil, Water & Herbage Testing Testing is often discussed in agriculture, but rarely done in a way that truly guides decision-making. In this episode, Stephen and Ewan walk through the practical process of soil, water, and herbage testing, showing how accurate sampling, consistent GPS points, and year-on-year comparisons reveal what is really happening on a farm. From collecting soil cores and tracking carbon through the soil profile, to interpreting herbage and water results alongside animal performance, this episode shows why testing works best when it is used to understand the whole system, not just individual numbers. We discuss:• How to collect repeatable soil samples and why depth matters• What soil carbon, bulk density, and mineral balance reveal over time• How boron, calcium, silicon, copper, and zinc influence soil and pasture function• What herbage and water testing can tell us about animal health and nutrient flow This episode is about learning to read your own farm, identifying limiting factors, and making informed decisions based on observation, data, and experience over time.

An EcoFarmers Discovery Chapter 11: Rock Hounds Welcome 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 11, Rock Hounds, is where curiosity turns into full-blown experimentation. Ewan unpacks what happened when basic slag disappeared from the fertiliser market, how silicon was quietly stripped from key inputs, and why farming systems began to unravel as a result. From disastrous springs and animal health breakdowns to sheep chewing clay banks and grass thriving where road dust falls, this chapter reveals how nature keeps leaving clues, if you’re willing to notice them. This episode dives into silicon’s critical role in soil structure, animal health, plant strength, and mineral availability. We explore why weeds like thistles, gorse, and willow weed are not the enemy, but messengers, and how biology, electricity, and rock dust intersect in ways modern agriculture has largely ignored. We explore:• Why removing silicon from fertiliser inputs caused widespread animal health issues • How weeds act as remedial plants, restoring what soils are missing • Why sheep chew banks, cows reach through fences, and grass thrives near roads • The role of silicon in bone structure, plant strength, and soil resilience • What marine clays, rock dust, and cyanobacteria reveal about soil electricity • Why proper trials must start with a baseline — or they mean nothing Packed with insight, humour, and hard-earned lessons, this episode reinforces a powerful theme: if the numbers don’t match what you see on the farm, the numbers are wrong.

| Inside EcoFarm Aotearoa: Late Spring Open Day | 16 déc. 2025 | 01:15:51 | |
Inside EcoFarm Aotearoa: Late Spring Open Day The EcoFarm Aotearoa Podcast (Ep. 11) Many farmers are feeling the pressure of rising fertiliser costs, tightening margins, and systems that no longer seem to deliver what they promise. In this Late Spring Open Day, Stephen and Ewan are joined by farmers, orchardists, and lifestyle block owners who are actively questioning the status quo and exploring what happens when you stop following the rulebook and start listening to the land. Across paddocks, fences, and soil pits, the conversation moves from conventional inputs to biology, minerals, energy, and observation. This episode captures real questions, lived experiences, and practical insights from people transitioning away from chemical dependency and toward systems that build soil, support animals, and improve resilience over time. We discuss: • Why many farmers are rethinking fertiliser, sprays, and conventional advice This episode isn’t about perfection or overnight change. It’s about learning, questioning, and building systems that work with nature rather than against it, one paddock, one decision, and one season at a time.

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