This episode was recorded live at the third Grounded Festival at Yan Yan Gurt West farm in Victoria’s Otways. One of my highlights of the festival was hearing from third-generation New Zealand dairy farmer Gavin Fisher. Although, dairy is only the tip of the iceberg of Gavin’s farm. He also raises deer, chickens and ducks, and bees. The pastures are multi-species, but every paddock is also surrounded by diverse plantings of trees and shrubs, including fruit and nut trees, and medicinal plants for the cows.
This is the product of a decades-long process through which Gavin has steadily transformed his family’s farm from a flat, treeless series of paddocks, into a diverse and multi-layered production system. With the principle of biological diversity and synergy at the centre of his vision, and farming deeper and higher rather than expanding his land area, Gavin has created a low cost, minimal input, highly resilient and profitable enterprise that is filled with life:

What happens when a commercial dairy farm runs regenerative and conventional systems side-by-side, and measures the results?
In this episode, Clare Buchanan from Align Farms shares insights from an ongoing trial in Mid Canterbury, New Zealand. Half the farm is managed conventionally, while the other half uses diverse pastures, lower synthetic inputs and a different approach to grazing and stocking. The aim has been to test how these systems perform in the same conditions, across production, environment and profitability.
Clare talks through what they’ve been observing in the five years the trial has been running, including pasture production without synthetic nitrogen, how soil biology is tracking, and what they’ve learned about pasture diversity over time. Early research is also pointing to differences in milk quality, with links between pasture composition and fatty acids and plant compounds in the milk.
Financial performance is a key part of the trial. The regenerative system is currently profitable, but not yet matching the conventional side, largely due to lower stocking rates and production. As input costs shift and the system continues to evolve, that gap is something they’re watching closely.
Clare reflects on what they would do differently, what still isn’t clear, and where there may be opportunities for farmers looking to test similar approaches on their own farms.

Australia's fertiliser crisis has been building for weeks as a result of the conflict in the Middle East. Around 60 per cent of Australia's urea imports travel through the Strait of Hormuz, which has been severely disrupted, leaving shipments stranded and future orders cancelled.
Some reports suggest urea prices have already more than doubled since December 2025, from around US$350 per tonne to US$750, and there are serious doubts about whether any supplies will be available beyond the next few months if the conflict continues.
Even if stock becomes available, the prices are eating into margins, with reports that many growers are choosing to cut production because the economics simply don’t stack up.
The federal government has formed a Fertiliser Supply Working group and responded with a package of measures including new legislation to underwrite the import of emergency fertiliser supplies.
But what can producers themselves do? Today we're talking to soil and plant health educator Joel Williams about what farmers can do right now to manage this situation on the ground.

Dr Jonathan Lundgren runs 1,000 Farms, the largest and most comprehensive study of regenerative agriculture anywhere in the world. Despite the name, the program now includes more than 2,000 farms across all eco-regions in North America, with a minimum of 500 data types for each farm, including data on production, economics, soil, water, biodiversity, carbon, nutrition and more. The results - according to Jon - are illustrating what farmers themselves have been reporting, that working with natural systems on farms can be as profitable, with greater stability and resilience, improved environmental outcomes and much improved mental and physical health and wellbeing for the farmers.

But that incredible research is just the tip of the iceberg of this conversation. After a highly distinguished scientific career, including a PhD in entomology, more than a decade with the USDA, receiving the Presidential Early Career Award for Science and Engineering, and writing more than 100 peer-reviewed journal articles, Jon pivoted.

He established Ecdysis Foundation, a nonprofit organization based in Estelline, South Dakota, dedicated to advancing regenerative agriculture through relationship-based, independent research, and bought and now runs a farm - Blue Dasher Farm. He has become a passionate advocate for reorienting food and agriculture systems away from centralised corporate commodity chains and back to the farmers on the land, their health and wellbeing, and that of the communities in which they operate. This, he argues, is the pathway to more secure and resilient agriculture, and to realising the true potential of regenerative agriculture to deliver on our most pressing social, economic and environmental issues.

Dr Mary Retallack is an agricultural scientist, third-generation viticulturist and agroecologist who has spent more than three decades advancing environmental stewardship within agricultural landscapes. She grew up on a fruit block in SA's Riverland growing grapes, apricots and pears, and now lives on a small vineyard and apple orchard surrounded by native insectary plants in the Adelaide Hills.
Mary is the founder and custodian of the award-winning National EcoVineyards Program, working in collaboration with more than 175 program partners and wine growers across fifteen regions in four states to build functional biodiversity, restore soil health, and reduce reliance on synthetic inputs.
Mary’s PhD research in viticulture and plant protection focused on native insectary ground cover plants and the role they play in supporting natural predators of vineyard pests. Her findings show how functional diversity not only builds ecological health, but delivers economic benefits to growers, and there are heaps of detailed case studies from growers around the country on the EcoVineyards website.

With funding from the Australian Government’s Climate-smart Agriculture Program, we’re working over the next three years with perennial horticulture growers across Australia to strengthen soil health and landscape function in tree and vine crops.
