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 […]

Robin Tait from Tasmania has a background in agronomy, after ten years in pyrethrum production. A Nuffield Scholarship in 2018 took her all over the world looking at different farming systems. This led to a career change for Robin who is now an independent consultant, specialising in regenerative agriculture and working with multispecies cover crops. Although in its early stages, Robin has recently added another string to her bow, being mentored and guided by Jane Slattery to begin integrating Natural Intelligence Farming into her consulting. Natural Intelligence Farming helps people with integrating true presence of self with decision-making to help people transition from management to stewardship of their land. Robin is also a key member of the NutriSoil HUB Care Team. Today Robin and I discuss her reasons for changing her career path to work more holistically with farming, food, diversity, and people. We also discuss the enormous barrier healthy food production systems are faced with, which is disadvantaging both farmers and consumers.

Today’s conversation is with Anthony Thomas and with me co-hosting is Dr Charles Massy. We recorded this podcast in March when we were there for the Three Springs Biological Farming Roundtable.
Anthony and Geraldine Thomas farm approx. 8000Ha in the North Midlands of W.A at Three Springs. Anthony and Geraldine operate Hill Padua Polls, breeding multipurpose Merinos, and crop 1300 Ha regeneratively. Adam Thomas their great nephew share farms the rest of the cropping program.
Anthony has always been focused on soil health starting in the 1970s working with Agro Nutritional Research Laboratories run by the late Tom Arkley who analysed their soils and pastures. Arden Anderson has been another influence for Anthony.
For the past two years, Anthony’s cropping system has dropped fertiliser inputs down to 5 units of Nitrogen and 5 L of NutriSoil at sowing and as a foliar, and he has been using NutriSoil and calcium across his pastures.
The combination of careful genetic breeding, low stress sheep management and working with nature has resulted in quiet, highly fertile sheep that do not require mulesing. His soils are visually increasing soil organic matter and measuring decreased compaction.
Dr Charles Massy, my special co-host is a Monaro woolgrower, a scientist and a renowned author. His classic book The Australian Merino: The Story of a Nation, is the account of how Merino sheep became one of the main supports of the Australian economy. More recently, Charles’ book Call of the Reed Warbler: A New Agriculture, a New Earth, exemplifies his role as an advocate for regenerative agriculture.
This is my enlightening conversation with Anthony Thomas and Dr Charles Massy.
