The Carbon Trap: Why Pasture Renewal Is Costing You More Than You Think

The EcoFarm Aotearoa Podcast (Ep. 9)

Most farmers know carbon is important, but few realise just how fast it can vanish or what’s really driving the losses. In this episode, Stephen and Ewan break down a Grasslands Conference presentation by soil scientist Louis Schipper, and compare his findings with what’s actually happening on real farms.

From pasture renewal to maize cropping, chemical sprays to root systems, this episode takes you far beyond the theory. As Ewan explains, the numbers don’t lie, but the interpretation often does. Behind every carbon crash is a deeper biological story, and ignoring it costs farmers thousands in fertility, grazing, and long-term soil health.

Together, Stephen and Ewan unpack the hard science, challenge long-held assumptions, and reveal why cyanobacteria are the missing link in New Zealand’s carbon cycle. Once you understand how soil biology really works, everything changes: carbon stabilises, nutrients rise, organic matter builds, and paddocks recover faster than anyone expected.

We discuss:
• Why pasture renewal causes huge carbon losses — and why recovery often never happens
• How chemical sprays wipe out cyanobacteria and crash soil fertility
• Why maize looks great the first year but drains carbon for years afterwards
• The surprising role cyanobacteria play in nitrogen, phosphorus, and sulphur availability
• Practical steps Ewan uses to lift organic carbon by 1–2% a year without expensive inputs

With clarity, humour, and decades of hands-on fieldwork, Stephen and Ewan translate complex soil science into practical solutions any farmer can use. This episode connects research, real soil tests, and on-farm experience into a roadmap for restoring soil carbon the natural way.

Soil Health: The Real Cure for Facial Eczema

The EcoFarm Aotearoa Podcast (Ep. 6)

When a facial eczema outbreak tore through Ewan Campbell’s dairy herd in the late 1980s, it became a make-or-break moment on the farm. Cows were peeling, milk production was crashing, and the conventional advice—more zinc, more maize, more fungicides—wasn’t working. Then one old farmer offered the simplest, most game-changing advice of all: “Just put some lime on.”

In this episode, Ewan and Stephen unpack how a crisis in animal health revealed a deeper truth about soil. What started as a desperate search for a cure led to a breakthrough understanding: that facial eczema isn’t just a pasture disease—it’s a soil problem rooted in acidity, imbalance, and over-reliance on chemicals.

We discuss:
• The shocking reality of facial eczema outbreaks and why prevention starts underground
• How one “lime experiment” dropped spore counts from 300,000 to under 20,000 in days
• The hidden role of soil pH, nitrates, and fungal balance in livestock disease
• Why quick fixes like zinc and fungicides only mask the real issue
• The true cost of ignoring soil biology — in money, animal welfare, and mental strain
• Why farmers need to think critically, ask questions, and reclaim independence from “expert” advice

With humour, honesty, and decades of hands-on experience, Ewan and Stephen explore how solving facial eczema starts with healthy soils, balanced biology, and a shift in thinking.

What Really Saved My Cows

The EcoFarm Aotearoa Podcast (Ep. 5)

When 25-year-old Ewan Campbell faced a devastating facial eczema outbreak on his dairy farm, it nearly cost him everything. Cows were dying, money was vanishing, and the standard advice wasn’t working, until one old farmer’s suggestion changed everything: “Just put some lime on.”

In this episode, Ewan and Stephen revisit the story that shaped a lifetime of discovery. What began as a crisis became a turning point, revealing how soil health, not quick fixes, holds the true key to animal wellbeing and farm success.

We discuss:
• The shocking impact of facial eczema and how it nearly broke the farm
• The moment lime proved to be the unexpected cure
• Why soil balance and complete proteins matter more than chemicals
• How high nitrates and poor soil structure fuel disease
• Why prevention, not reaction, is the real solution
With honesty, humour, and hard-earned lessons, this episode unpacks how one farmer’s challenge became a breakthrough in understanding the deep connection between soil health, livestock vitality, and farming resilience.

Nitrate Poisoning: Farmers Blamed, but What’s the REAL Cause? | The EcoFarm Podcast (Ep. 2)

Is nitrate really the villain behind blue baby syndrome, sick livestock, and rising cancer rates, or have we been pointing fingers in the wrong direction? In this episode, Ewan Campbell and Stephen Brunton dive into New Zealand’s nitrate crisis and ask the hard questions no one else will.
From Environment Canterbury’s recent “nitrate emergency” to the ongoing debate between professors and farmers, we unpack the real science behind nitrate poisoning, synthetic nitrogen use, and how it is impacting our water, soil, animals, and human health.

You’ll discover:
 - The difference between nitrate and ammonia in healthy soil systems.
 - Why livestock suffer from oxygen deprivation and what that means for methane production.
 - How synthetic nitrogen and irrigation create toxic imbalances in our food chain.
 - What “blue baby syndrome” reveals about our water quality
 - Real on-farm results showing how regenerative practices can fix the nitrate problem quickly.
 - This episode isn’t about blame. It’s about truth, responsibility, and practical solutions that start in the soil. If you care about clean water, healthy animals, and food you can trust, this conversation will change the way you see farming.
