Biological Farming Roundtable

In Episode 49 of the Biological Farming RoundTable host Nakala Maddock is rejoined by David Hardwick from Soil Land Food and Luke Harrington from Re-Gen Farming. This episode is part two of the Managing Regenerative Transition series, where the team unpack the types and stages of transition or change, what to expect and where to go to get resources and support. Luke and David share their top tips to help you regain control of your farming operation.

Biological Farming RoundTable host Nakala Maddock is joined by David Hardwick from Soil Land Food and Luke Harrington from Re‑Gen Farming in Episode 48. In part one of this two‑part series, they explore the motivations and challenges behind transitioning to regenerative farming. They also reveal some unexpected factors to watch for — insights that can help you regain confidence and control in your farm management journey.

In the first episode of the Biological Farming RoundTable for 2026, Nakala sits down with NutriSoil’s tech‑savvy Nige for a candid, sometimes confronting, and ultimately empowering conversation about the rise of AI in agriculture.
What begins as a simple chat about who owns AI quickly opens into a deeper exploration of ethics, power, risk, and opportunity. Nakala and Nige unpack the major players behind today’s AI platforms, how algorithms shape the answers we receive, and why farmers need to stay alert as technology accelerates faster than policy.
Nakala then switches on voice‑activated ChatGPT and interviews it as an “AI agronomist,” asking it to respond to real‑world farming scenarios. Together, they explore how AI could support farmers with soil tests, rainfall patterns, sowing windows, pest prediction, grazing management, nutrient density, and the future of on‑farm sensors.

In Episode 46 of the Biological Farming RoundTable Podcast, Nakala and Shelley travel to Pingrup, in the southeast of the WA wheatbelt. They are joined by David Steele and his wife, Deb, who are multigenerational farmers running a cropping and sheep enterprise. David and Deb recall when the soil had that earthy smell and have their sights set upon bringing the aroma back to the farm.
When David relied mainly on synthetic fertilisers, he watched his soil health steadily decline. He shares the steps he’s taken, such as addressing all of his plants’ nutrient needs, including trace elements, with a mineral fertiliser, and more recently adding biology to the mix. He has watched his topsoil steadily increase and he still has some tools up his sleeve to add to the system.

In Episode 45 of the Biological Farming RoundTable Podcast, Nakala continues her conversation with Gundi Rhoades in part two of The Microbe Solution. This episode dives deeper into Gundi’s exploration of the powerful connection between soil microbes and human health. We examine how synthetic compounds have disrupted microbial balance and how farmers play a critical role in restoring it.
Gundi shares compelling insights on why rebuilding soil biology is not just achievable but essential for the future of farming and wellbeing. A must-listen for anyone passionate about regenerative agriculture and the ripple effects of healthy soil.
