Figuring out regenerative grain in the paddock and beyond, with Courtney Young
Courtney Young farms organic grain with her husband Ian in Rutherglen, Victoria, and is also Soils for Life's Farmer Learning Manager. In this episode, she talks with Eli about building a farming life from scratch, growing healthy soil and grain, and turning wheat into a value-added business. In this episode How Courtney's path into farming began, from her dad's oyster farming on the NSW South Coast, through a disillusioning stint in conservation, to discovering regenerative agriculture The economics of getting into farming today, and how Courtney and Ian navigated the challenge of accessing land Building soil and crop health on their 100-acre property and the family's 2,000-acre organic farm at Berrigan, including intercropping wheat with clover and improving grazing management The decision to start milling their own flour, turning a commodity crop into a paddock-to-plate product with a loyal following among Melbourne bakers How Courtney and Ian test new ideas cheaply and quickly, and "fail fast" rather than risk the whole business Soils for Life's new Cropping Communities program, an eight-location, on-farm and online initiative helping grain growers and mixed farmers interpret soil and plant health data and turn it into action plans Find out more If you're interested in the upcoming Cropping Communities training program for growers and cropping advisors, head to soilsforlife.org.au/cropping-communities/ Get in touch If you have any feedback or questions about this podcast, or suggestions of topics or people you’d like us to include in future episodes, please reach out on social media or via info@soilsforlife.org.au.

The network underpinning it all: Fungi with Dr Sapphire McMullan-Fisher and Julie Fielder
World Fungus Day is in October and to mark the occasion we spoke with two mycologists - fungi experts - Dr Sapphire McMullan-Fisher and Julie Fielder about this amazing and mostly hidden lifeform. Sapphire is a lecturer in plant and fungal Ecology at the University of New England and Julie runs consultancy Phytos Environmental in WA, and both are involved with Fungimap, one of Australia’s longest running citizen science organisations. They’ve both also been involved in the recently published book Fungi for Land: A practical guide for land managers, which draws on the work of more than 25 Australian scientists to explain what fungi do in the landscape and how to manage land in ways that support them. In this conversation we delve into the weird and wonderful world of fungi, from their ancient beginnings almost 400 million years ago as partners to plants, to their incredible and bizarre present day forms. And we discuss how healthy and diverse fungal ecosystems are so deeply interconnected with, and essential for, healthy and resilient soils, plants and people. Correction: In the intro we say World Fungus Day is on October 2nd. The date actually varies by country, it's marked across the first week or so of October rather than on one fixed day.Mentioned in this episode: Fungi for Land: A practical guide for land managers - https://fungi4land.com/ Fun Fungi Ecology - https://www.funfungiecology.com/ Fungimap - https://fungimap.org.au/ iNaturalist - https://www.inaturalist.org/ PhD on metarhizium - https://eprints.qut.edu.au/117674/

Feeding the soil first: Hugh and Katie Finlay on diversity at every level
Hugh and Katie Finlay manage a 30 hectare farm in Central Victoria, including a commercial stone fruit orchard and fruit tree nursery. The farm also includes a range of small enterprises run by others under the banner of the Harcourt Farming Co-op, including a dairy, market garden, and bush foods plot. Since 2013, Hugh and Katie also have been educating others in how to grow organic and regenerative fruit through their business, Grow Great Fruit. Perennial horticulture is a fairly new area for me, but this conversation reveals some very familiar themes. Hugh and Katie focus on the soil above all else, and have seen how taking care of soil biology by adding organic matter, fostering plant diversity, and elimination of all synthetic inputs supports healthy trees that are resilient to pests and disease and require little in the way of pest and disease management. While many of their strategies are applicable at much larger scale than their now downsized operation, Hugh and Katie are also passionate about the value of smaller scale ... about the value of smaller scale enterprises to not only support resilient agricultural businesses, but also connected and thriving regional communities. Please enjoy this delightful conversation with Hugh and Katie Finlay. And if you're an orchardist yourself or interested in perennial horticulture, don't forget to check out our website for all the resources and events that we're rolling out through our Orchard Resilience project.

Creating diversity above and below the ground: Murray Gomm on cover crops in orchards and vineyards
Murray Gomm is a regenerative farmer and winemaker based near Albany in Western Australia. With his partner Pamela Lincoln, he runs Oranje Tractor Farm, a small organic vineyard and orchard that’s become known for its focus on soil health, biodiversity and carbon-positive farming. Since the late 1990s, Murray has transformed a degraded property into a thriving, diverse landscape producing wine, fruit, and olive oil. The farm integrates cover crops, composting, mulching, and biological soil management instead of relying on synthetic fertilisers and chemicals. Murray is a long-time advocate for working with natural systems and is passionate about sharing the message that healthy soils lead to better produce and stronger communities. He regularly speaks on sustainable tourism, carbon farming, and the intersection of agriculture and ecology. In our conversation, we talk about the value of having a peer group to learn with rather than operating in a vacuum, the role of cover cropping in building diversity and unlocking crop health, soil and plant health monitoring that have helped Murray grow his best tasting peaches ever, and why he now sees himself as a ‘manager of ecological relationships’.

The power of pasture analysis, with Emily House
Emily House began her career as a geologist before an unlikely path led her into ruminant nutrition. After moving to New Zealand, she started working with two vets who wanted to shift from treating livestock disease reactively to preventing it, which meant looking closely at pasture as the major component of the diet. Emily brings a background in earth science to her work interpreting pasture and soil analysis for animal health and performance. She was part of the team that developed the DietDecoder™, an online tool that assesses the mineral profile of pasture and flags risks to animal health before they show up as clinical problems. In this episode, she explains why testing the mineral content of pasture goes further than the more familiar measures of dry matter, crude protein and energy that many farmers already use. She talks through real examples, from calcium and milk fever at calving, to copper deficiencies caused by excess sulphur and molybdenum in the soil, and how these mineral gaps can affect everything from hoof health to wool quality. We also discuss the range of responses available once a problem is identified, from targeted supplementation through to adjusting fertiliser regimes and building more mineral-dense pasture through species diversity, along with some striking parallels between what we're learning about animal nutrition and human health. In this episode Emily's path from government geologist to ruminant nutrition consultant Why pasture mineral testing reveals more than standard dry matter and protein analysis How mineral deficiencies and excesses show up in animal health, from milk fever to coat and wool quality The DietDecoder™ tool, and how it's used seasonally around key events like calving and mating Addressing mineral imbalances through supplementation, fertiliser decisions and pasture diversity Parallels between livestock nutrition and the gaps in our understanding of human nutrition Links and resources DietDecoder™ – dietdecoder.nz, including the quote from Dr Pat Poletti referenced in this episode in the FAQ Register to join our upcoing Dairy Convo where Emily will talk about Pasture Nutrition.

Regenerative grazing and the key insights of Holistic Management, with Brian Wehlburg
Brian Wehlburg is one of Australia’s most highly regarded Holistic Management educators and a board member of Holistic Management International and the Australian Holistic Management Cooperative. He has delivered training and consulting to businesses, land managers, families, environmental groups and pastoralists all over Australia, as well as in New Zealand, USA and Zimbabwe. He is also a farmer himself, having experience growing crops in Southern Africa, working as a pasture and cattle manager in South West Queensland and managing a mixed-species property in New South Wales. This is one of the longer conversations we’ve featured on the podcast, but it easily could have been twice this length given the depth of Brian ’s well of knowledge and experience. We talk about his perspective on regenerative grazing, about the key insights of Holistic Management, the deeply held paradigms that often prevent people from seeing these insights, the practical steps that he has seen work to help people get started, and the positive life changes that can result when people succeed. This episode is one of a series of interviews we’re doing with graziers and educators involved in the development of our recently released guide to grazing for soil and landscape regeneration.

Building confidence in multispecies pastures, with Grant Williams
Grant Williams is a dairy farmer at Hallora in West Gippsland, Victoria, where he and his wife Leesa run Willora Farms - an almost 600-cow operation across 430 hectares. He has been a generous and engaged contributor to the dairy community for many years, and previously served on the Board and as Chair of GippsDairy. Despite having been an early adopter of robotic milking, Grant describes himself as cautious about making changes on the farm. Over the past decade, however, he has made a change that many dairy farmers wouldn’t dream of, transitioning the whole farm to multispecies pastures, and in the last four years, cutting out all synthetic fertilisers. In this episode, Grant describes how he ‘fell into’ multispecies pastures, how his early trials didn’t work out the way he hoped, and how he eventually became confident that he could profitably roll out multispecies across the whole farm.

Working with biological control agents in perennial horticulture, with Dr Paul Horne
Dr Paul Horne is an award winning entomologist and founder of integrated pest management consultancy IPM Technologies. He began his career at the Victorian Department of Agriculture in the mid-1980s, his work has been published across scientific journals and industry platforms, and he has written several books on insects and pest management. Paul’s work focuses on supporting adoption of IPM strategies to manage invertebrate pests in a wide range of crops including cut-flowers, berries, vegetables, tree and vine crops, nurseries, broad-acre crops and pastures. As our new initiative to support fruit and nut growers kicks off, I wanted to talk with Paul about the state of play with integrated pest management, and what he has found works well to support adoption of IPM in perennial horticulture. If you’re involved in perennial horticulture, check out our new Orchard Resilience Project. 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.

Managing risk in grazing through safe-to-fail farm trials, with Graeme Hand
Graeme Hand is a holistic land management and grazing educator based near Bairnsdale, Victoria, where he has farmed for more than 35 years. He came to the land via an unlikely route, a decade as an industrial chemist, before applying that scientific background to regenerative agriculture. A Certified Holistic Management educator and Board member of Regenerative Agriculture Network Tasmania, Graeme has been supporting farmers in adopting regenerative grazing techniques since 1996, and has spent the better part of three decades helping farming businesses rebuild topsoil, restore pasture, improve the water cycle and strengthen their resilience to a changing climate. At the heart of Graeme's work is a conviction that lasting change on the land starts with the decisions made each day in the paddock, with ‘safe to fail’ trials at the heart of his approach. As Graeme explains in this episode, trials are the key strategy that enables farmers to manage the complexity of biological approaches to grazing. It was a pleasure to record this episode with Graeme, live from the Grounded festival in Victoria, and I hope you enjoy our conversation. ** Keep an eye out for our new grazing practice guide, which will be launched on the 20th of May at a special field day and launch event in Mundarlo NSW.

‘Intensification’ through biology, synergy and farming deeper and higher, with Gavin Fisher
Find out more and register for the special event to launch our Introductory Guide to Grazing for Soil and Landscape Health, on 20 May at Nick Austin’s farm in Mundarlo, NSW (near Wagga) - events.humanitix.com/grazinglaunchfieldday 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: Links and resources: Gavin’s Instagram - www.instagram.com/off_the_planet_organics Gavin’s LinkedIn - www.linkedin.com/in/gavin-fisher-a28b8280 If you have feedback, questions, or suggestions for future episodes or guests, we'd love to hear from you - reach out on social media or at info@soilsforlife.org.au.

Tracking milk quality, profit and soil health: A five year regenerative trial.
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.

RAPID RESPONSE: Managing the nitrogen fertiliser crisis, with Joel Williams
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.

Studying regenerative agriculture at scale: The human experience behind the hard data, with Dr Jonathan Lundgren
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.

Nature’s army: Using functional biodiversity for biocontrol in orchards, with Dr Mary Retallack
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.

Earning the right to reduce pesticides: Building plant resilience with Brad Campbell
Western Australian farmer Brad Campbell has spent years refining his mixed cropping system to build healthier, more resilient plants and reduce reliance on synthetic inputs. Over time, he’s cut out routine fungicides and insecticides, moved away from chemical seed treatments, and now only uses pesticides strategically when needed. In this conversation, Brad talks about how targeted plant nutrition, sap testing and careful observation are helping him make management decisions and improve crop health. Brad shares how his family’s early shift toward biological farming set the foundation for his approach, why monitoring matters more than ever, and what he means when he says you have to earn the right to reduce pesticides. Brad’s story features in our Practice Guide on Building Plant Resilience to Pests and Diseases, which brings together insights from farmers and experts across Australia. You’ll find it at soilsforlife.org.au In this episode Why Brad says you need to “earn the right” to reduce pesticides How sap and tissue testing inform his nutrition decisions Using observation and small-scale trials to guide change What’s changed in soil function and disease pressure over time Lessons from experimenting, learning and staying profitable Resources Practice Guide: Building plant resilience to pests and diseases https://soilsforlife.org.au/practice-guide-building-plant-resilience-to-pest-and-disease/ Explore more cropping practice guides and farmer stories at soilsforlife.org.au Brad mentioned a course by Neil Kinsey: https://kinseyag.com/ Brad also mentioned a course by Arden Anderson: https://soillearningcenter.com/product/sustainable-agriculture-course/ This short episode of the Soils for Life Podcast was hosted by Eli Court and produced by Chris Wieffering.

SHORT: From problem paddocks to healthy soils, multispecies with Grant Sims
This episode of the Soils for Life podcast is part of our series of mini-episodes with farmers profiled in our series of cropping practice guides. In this short episode, Eli Court chats with Victorian farmer Grant Sims about how multispecies cover cropping has transformed his mixed farming system at Pine Grove near Lockington. After moving away from synthetic fertilisers, fungicides and insecticides, Grant began experimenting with diverse seed mixes to bring more life back into his soils. He explains how integrating livestock with multispecies crops built soil structure, reduced weed pressure and improved resilience during tough seasons. Grant also shares what he’s learned about designing mixes for different paddocks, fixing nitrogen through cover crops, and cutting input costs without sacrificing productivity. Along the way, he’s learnt through trial and error from experiences like underestimating the importance of weed control before sowing and trying to “add biology” to soils that weren’t yet ready for it. He talks openly about these lessons, as well as his current experiment sowing his whole farm with zero nitrogen for the first time. Highlights How Grant “stumbled into” multispecies crop mixes and scaled them over time The role of livestock grazing in improving performance and reducing risk How cover crops can build fertility, especially nitrogen fixation and phosphorus unlock Lessons he’s learned, e.g. weed control, applying biology to soils not ready for it Taking the leap: sowing with zero nitrogen and watching the system work What he wishes he’d known earlier Resources & links Read the full Practice Guide on Multispecies Cover Cropping: https://soilsforlife.org.au/practice-guide-multispecies-cropping/ Down Under Covers: https://www.downundercovers.com/ If you enjoyed this episode, please rate & review it on your podcast app and share it with others.
