An EcoFarmer’s Discovery Chapter 14: The BeachThe EcoFarm Aotearoa Podcast
Welcome to An EcoFarmer’s Discovery: The Companion Podcast, where every Friday we dive into one chapter of Ewan Campbell’s journey.
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.
In This Episode This episode covers Chapter 14 and explores the role of seawater, cyanobacteria, and marine minerals in soil, plant, animal, and human health.
Ewan reflects on the research of Dr Maynard Murray and others, drawing connections between ocean health, mineralisation, and biological function on land. The discussion explains why seawater cannot be replicated synthetically, how cyanobacteria underpin carbon accumulation, and why biology fails when exposed to chemicals and aluminium.
The conversation moves from theory to practice, covering early on-farm seawater trials, logistical challenges, mineral interactions, and surprising results such as explosive pasture growth and worm activity. The episode also touches on serpentine, historical fertiliser choices, and why relying on short-lived products can leave farmers stuck when tools disappear.
We explore: • Why seawater is biologically alive and cannot be manufactured • The role of cyanobacteria in carbon, soil structure, and nutrient flow • Links between ocean health, soil health, and animal performance • Seawater as fertiliser, fungicide, and biological inoculant • Practical lessons from early trials and mineral interactions • Why nature-based systems consistently outperform chemical fixes
This episode is about first principles, biological intelligence, and understanding that healthy farms, animals, and people all begin with functioning soil biology.

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.
