EcoFarm AotearoaShow Notes
An EcoFarmer’s Discovery Chapter 27: Environmental Issues 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 27: Environmental Issues, bringing the series to a powerful and challenging close. The conversation centres around one of the biggest topics in modern agriculture, water quality, and explores how soil health, carbon, and biology play a critical role in filtering nutrients, reducing runoff, and restoring natural balance.
Ewan shares insights into how increasing soil carbon can lock up excess nitrogen, preventing it from entering waterways, while also highlighting the importance of silica and microbial life in maintaining clean, functional water systems. The discussion challenges common narratives around farming’s impact on the environment, suggesting that many of today’s issues are not simply the result of farming itself, but of systems that lack the biological and mineral balance needed to function properly.
The episode also dives into the broader system, from outdated scientific paradigms and industry structures, to the role of policy, education, and accountability in shaping outcomes. Through practical examples and on-farm experience, Ewan explains how improving soil health can directly improve water quality, animal performance, and public health, all while reducing reliance on external inputs.
At its core, this chapter ties everything together, reinforcing the idea that true environmental solutions don’t come from regulation alone, but from understanding and working with the natural systems already in place. It’s a confronting but empowering conversation, pointing toward a future where farms can be both highly productive and environmentally regenerative.
We discuss:• How soil carbon helps reduce nitrate leaching and improve water quality• The role of biology and silica in natural water filtration systems• Why many water quality issues stem from imbalanced soil systems• The connection between soil health, productivity, and public health• How outdated thinking and systems can limit real progress• Why working with nature offers long-term solutions over regulation

What if the problem with your pasture, garden or lifestyle block isn't a lack of nutrients, but the fact that your soil can't access the nutrients already there?
What if the biggest financial asset on your farm is already sitting in the soil? In this episode, Scott Gordon joins the conversation to break down the financial side of soil fertility, looking at the value of minerals locked up in the soil, the cost of unlocking them, and how understanding your soil could change the way you assess farm value, productivity and return on investment. We also explore the idea of treating soil like a bank account, where better fertility management can turn an underperforming asset into productive cash flow.
Herbage testing can reveal a lot about what is happening in your soil, but timing and the right combination of tests are crucial. In this episode, Ewan and the team look at why mid to late spring can be such an important window for herbage testing in New Zealand, when multiple pasture species are actively growing and minerals can be better represented. The conversation explores the relationship between soil tests, herbage tests and soil biology, including trace minerals such as cobalt, selenium, nickel, boron and iodine. They also work through an anonymised farm example, looking at nitrogen, potassium, calcium, silicon, aluminium and other minerals to understand what the numbers may be showing about the wider soil system. They also revisit the response to the previous cropping episode, discussing how soil preparation, biology and nutrient cycling fit together, why plants such as wild turnip may be indicators of underlying soil conditions, and why soil testing should be the starting point when trying to understand what is limiting a farm.
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.
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.
