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

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.
