Soil Health and Regenerative Agriculture
Change is underway at Kioma Station near Toobeah in South-West Queensland, to improve profitability and create a more sustainable farming system.
Local landholders around Toobeah, west of Goondiwindi, were invited to a field day in June to see first-hand how farming country is being regenerated at Kioma, a large, mixed farming and grazing operation. The day was hosted by Southern Queensland Landscapes’ Emma King, whose husband Angus is the farm manager at Kioma.
Around 30 people braved the cool and windy weather to hear more about how to manage and improve soil health and ground cover with the help of multi-species plantings and vermiculture, from fellow land holders and agricultural service providers.
The day began with a talk from veteran farmer, Ran Mitchell, who took visitors back in time, to share he and wife Jenny’s journey over 50 years to regenerate the soil on their farm near North Star in North-West NSW.
The Mitchell’s began focusing on ‘regenerative’ agricultural principles decades ago, before the term ‘regenerative agriculture’ had been coined. Over the years they’ve developed a passion for harnessing and working with the natural rhythms of their land, flora and fauna. Unlike today, Ran was breaking new ground, figuratively speaking.
Rod and Maree Farrow, (Rod works for Ran on Leyland) run Vermagra – their worming farming enterprise. The team uses very few pesticides, plants multi-species cover crops and includes regular long fallows in the farming system.
“I watched the opening up of land for farming in what was to become known as ‘The Golden Triangle’,” Ran says.
“It didn’t take long before I could see and sense that we were working against our soil and nature in severe ways. The sound of shear bolts breaking on the neighbour’s blade plough as it hit stumps kept me awake at night and led me to the realisation that this was not the way forward.”
It was 45 years ago after having some basic water infiltration tests done on a stand of native vegetation and in a field that had been farmed since the 1930s that stands out.
“I can’t remember what the different infiltration rates were, but we were so dismayed we parked the disc ploughs we had and began no-till farming in earnest,” Ran said.
“To you people here, now is the time to form a vision for the future.
“To start, make just one plan to change one thing for the better.
“It’s ultimately about helping balance what we take out of the soil and putting back in the most natural way.
“One handful of fertile soil contains more living things than people on Earth – just recently we’ve learned that the underground livestock (biology) living in a hectare of healthy soil, would weigh eight tonnes.
“Eight tonnes of things we can’t see but need to grow and preserve.”
Kioma provided the perfect backdrop to discuss soil health, now nearly 15 years into a journey in regenerative farming. Much of the journey has been guided by Ian Moss from FARM Agronomy & Resource Management (FARM), who was on hand to share his knowledge and discuss options and decisions for planting and managing forages and/or pastures from a regenerative agriculture perspective. He’s working with Angus and farming manager Ewen who oversees the regenerative farming strategies, including their on-site worm bioreactors.
Ian says the aim is to build the capacity of the soil to improve productivity and profitability by focusing on soil quality, namely through increasing soil organic matter levels.
Kioma is a mix of clay vertisols, varying from red through to lighter black country and was previously managed in what is generally described as ‘traditional’ farming methods, in a winter-crop dominant system, heavily relevant on herbicides and synthetic fertilisers.
The current regenerative system grew from an early focus on nutrition.
“In the early days I was helping nutrition, which included a focus on soil testing and fertiliser rates,” Ian said.
“An initial step in this journey was to add liquid injections at planting and seed dressings to provide micronutrients with biological seed treatments.”
The next big step was looking at soil fertility as a whole and move to more long-term thinking and planning.
“As agronomists and farmers, we are really good at looking at a paddock and working out how to make the most money from it in the next six months,” Ian said.
“What we aren’t so good at, is understanding the impact of crop sequences, fallows and covers over 10 years, these are big things that make a difference to profitability.
“To determine what was needed long term required us to look at what was holding back yield, sub-soil constraints and a method to rebuild soil health over time.”
Changes at Kioma have included an aim to keep 20 percent of the area for summer cash cropping to spread risk and give opportunity to grow cover crops in long fallows. The farm works towards a five-year rotation of three winter cash crops in a row then a long fallow summer cash crop.
“We have moved chickpeas to the last winter crop before long fallowing to sorghum because it doesn’t have value as a standing stubble cover crop – we will plant cover after chickpea harvest at the earliest opportunity.
“The rotation plan rarely happens as planned and we deliberately throw out the five-year plan every time we have a decent fall of rain, or a planting window closes.
“By doing that and having cover crops in the mix we’ve been able to help Angus utilise them for grazing, which was particularly valuable in the last drought.”
They’ve moved away from pre-plant N application and are now using a spreader to add N in the form of sulphate of ammonia if, and when needed. Plant testing is another widely used tool.
“Often it’s the nutrient excesses that we deal with first before the deficiencies,” Ian says.
“By knowing what is left in the soil, post-harvest, all the options are open to us.”
Multi-species forage crops are a key to improving soil health. The field day visitors had a close look at a field planted with oats, barley, triticale, wheat, field peas, vetch, tillage radish, forage brassica and falcon leafy turnip. The multi-species aspect is building better quality and quantity of forage and the diversity of plant roots helps build the soil through promoting biological growth and water infiltration.
The next big step will bring the worms into the mix, starting this year. A liquid extract from the vermicast will be used for seed dressing, liquid injection at planting and as foliar treatments to reduce reliance on synthetic fertilisers.
Ian says the interest in regenerative agriculture is certainly growing. So what brings landholders to explore regenerative ag?
“There are two main reasons landholders come to us,” he said.
“Either they’ve seen and heard about regen ag and what we do, or, more and more I’m getting phone calls from people saying ‘I don’t know what I need to change but know I need to change something’ mainly because they’re experiencing increases in farming costs but not seeing this translated into increasing yields.
“My job is to make ‘sustainable farming profitable’.
“It is really about the farming system and starting to understand and appreciate the actions we take and how they affect everything else, in terms of the long-term health of our soil – which is the greatest asset we have on our farms – if it is healthy.”
The field day wound up with a presentation from Christian Capp from Data Farming who gave a practical and useful outline of the value of data and mapping to manage soil and farming systems.

When Sophie and Adrian McInnerney began adopting their “paddock to plate” experiment into their lambing business, they quickly discovered how a new and exciting approach to running their enterprise transformed their resilience and soil health. Multi-species cover cropping was the answer, and now their business has become a diverse enterprise that has embraced variations in livestock feed and crop rotation, building riparian fencing, and investing in healthier soils. This has opened the young couple to new opportunities to create new revenue streams, protect their business against natural disasters, drought, and prepare for economic hardships. Their property, “Bellhaven Brook”, located just an hour east of Goondiwindi, was the site of Macintyre Ag Alliance’s latest Multi-Species Cropping Field Day. With the support of Southern Queensland Landscapes (SQ Landscapes), the event aimed to promote the McInnerney family’s new land practices, offering an opportunity to educate land managers in the region of new ways to strengthen their property and enterprise. SQ Landscapes’ Goondiwindi-based Project Delivery Officer Keith Walker joined land managers for the workshop and highlighted how multi-species cover cropping could pave the way to rebuilding healthy soils and farming enterprises. “What was great about visiting ‘Bellhaven Brook’ is that you don’t have to be a scientist to understand this stuff. The idea is to just try and experiment like the McInnerneys did,” Keith Walker said. “These cover cropping systems are all about building your experience, experimenting and slowly developing a healthier and richer soil profile; which is the basis of all businesses; cropping and grazing alike.” Mr Walker said. “It was interesting to see the range of people, the ages from young and old, and the differences in enterprises. It’s a reminder that this genre of agriculture is starting conversations,” he said. “It’s all about implementation on the ground and getting the results for less money and experimenting with what people are doing.”
Cool burns, camels, and funding for local farmers were on the agenda at 'Risdon Stud' as land managers Nick and Liz Suduk hosted the Southern Queensland Landscapes and Department of Resources site visit to showcase the success of the Natural Resources Investment Program 2018-2022 (NRIP). Risdon Stud, south of Warwick, was primarily a high-intensity horse stud, but under new ownership with the Suduk family, the focus has been on restoring productivity and landscape health. “The Suduks participated in the NRIP project, where they received on-site guidance from First Nations fire practitioner Robbie Williams from Fire Lore, for cool burning in native vegetation areas,” Project Delivery Lead Natasha Mylonas said. “This was their first exposure to this type of burning and they have since embarked on a journey towards building their confidence in applying it elsewhere on the property,” Ms Mylonas said. “The NRIP project also supported livestock fencing, largely to exclude cattle from a large patch of remnant vegetation, combined with weed management in that remnant vegetation,” she said. “It is really difficult to muster out of the remnant vegetation, so the fencing has meant easier mustering of the cattle, as well as reduced weed spread and damage to the native vegetation in the patch.” “Outside of the NRIP project, they maintain a herd of agisted camels as part of their weed management strategy and experimented with fire to manage wattle regrowth,” Natasha Mylonas said.
Fire is crucial to maintaining our landscapes. That’s according to fire practitioner Robbie Williams, who accompanied Southern Queensland Landscapes earlier this year to bridge fire practitioner knowledge with First Nations Peoples across the southwest. Robbie has since returned to the region - this time accompanied by members of our Charleville team as he hosted training along the slopes of the culturally significant site of Mt Tabor, just outside Augathella. “This is the continuation of what we achieved last time we were in the southwest,” Robbie Williams said. “Last visit, SQ Landscapes connected me with local First Nations mobs including Kunya, Bidjara, Mardigan, Boonthamurra, Kooma, Kullilli, and Murrawurri,” Mr Williams said. “During this visit, many of these mobs agreed to trial fire practitioner training for young men in the area to bring burning back onto Country; and that is exactly what we’re here to do today!” he said. “It’s really inspiring to see these communities taking on the opportunity to learn about burning and we’re hoping this will develop into businesses the local mobs can build to manage their Country.”
Winners in the Southern Queensland Landscapes and University of Southern Queensland’s 2023 First Nations Art Competition have been announced to a crowd of more than 150 people in Toowoomba. Overall Grand Prize and Digital Medium Category winner has gone to Robert Claude Manns for his piece ‘Mandan’. "I wanted to express the fractured relationship that I have with some of the Mandandanji People. Unfortunately many of us feel connected to our Nation, but not always the people," Robert Manns said. "My piece was assisted through artificial intelligence (AI) art and I found that to be a really powerful tool in discovering how I wanted this art to go," Mr Manns said. "I've always been artistic, and I wanted to explore Indigenous art, but I wasn't great at it and I found the style difficult to personalise. AI and digital art has allowed me to connect with Indigenous art in my own way and explore things the way I wanted," he said. "I'm really glad it worked out and people liked the art!" "In truth, I thought I might only get an encouragement award, but to first see I won the digital art and then the Overall Grand Prize was just spectacular. There were tears in my eyes. I wasn't expecting to get so far!" Robert Manns said. "I want to thank everyone who made Indigenous art through the millenia; otherwise I wouldn't have done it," Mr Manns said. "Shortly before he passed away, my dad put me onto the competition and I thought I'd give it a go. I wish he was here to see it, as he was my inspiration for making this art." he said. "He was my inspiration and my supporter through it all."
By Kellie Stewart When land managers Phil & Anne Donges entertained the idea of retirement they looked to the natural assets of their property located between Yelarbon, Inglewood and Texas to provide the answer. For almost 90-years ‘Glenarbon’ had supported generations of the Donges family; with key crops and land use pivoting numerous times as a result of market demands, economic climates and practice change. “Glenarbon was established back in 1932; our family came out then and it was to grow tobacco, that was in the middle of the depression,” Phil Donges said. “Five years ago we sold our main farm about 10-kilometres down the road and we decided to go into semi-retirement keeping about 100-acres of the original farm along about 1-kilometre of the Dumaresq River,” Mr Donges said. “We’re using Glenarbon now to run a few head of steers and then we’ve also gone into this eco-tourism where people can come and enjoy the environment like we like it ourselves,” he said. “We saw the ecotourism as an opportunity to give us some extra income by going into the camping side of things, but also to diversify our business so that we could in tougher seasons rely less heavily on livestock and more on the natural assets of the farm.”
It’s amazing how quickly a landscape can rebalance itself according to Jarrod and Sam Thomson of ‘Gum Gully’, located some 14 kilometres south of Drillham in Queensland. The couple purchased the 820 hectare property in 2020 and since then have been working to reverse landscape damage caused by years of drought and overgrazing. “Gum Gully is a very diverse farm with a lot of timber ranging from Mallee box to belah, sandalwood and a lot of native pastures,” Jarrod Thomson said. “It’d been really knocked around by the droughts and our main goal was how do we bring back this place to make it a viable enterprise again?” Mr Thomson said. “Quickly realising that we had to rehabilitate the land and rehydrate it fast; desertification had set in and we were struggling to grow galvanised bur,” he said. Rehydration works included some contouring and soft engineering works combined with farm dams to slow the flow and manage water across the property to maximise each rain event regardless of whether it was 10mm or 100mm.
Reconciliation was on the agenda at Gummingurru for National Reconciliation Week. First Nations, local community, and avid gardeners came together for a round of truth telling and tree planting. Located north of Toowoomba, Gummingurru is an ancient and sacred site for Western Wakka Wakka Peoples, serving as a stopping point for First Nations Peoples on their way to the Bunya Mountains. Western Wakka Wakka man Shannon Bauwens, a First Nations man from the Bunya Peoples’ Aboriginal Corporation (BPAC) led the event with a smoking ceremony and a round of truth-telling at the yarning circle near Gummingurru. “Reconciliation is about talking to each other. Coming together and making something positive as a community,” Shannon Bauwens said. “This yarning circle we are standing in now represents thousands of years of storytelling,” Mr Bauwens said. “Today is all about sharing our stories and finding new ways to come together as a community; whether you are Indigenous or not,” he said. “We have people from all different Nations, from Western Wakka Wakka, to Bunjalung, Gomeroi, and more.”
Meet Lorinda Otto. She is Southern Queensland Landscapes’ latest addition to the team as our Relationship Lead and the incoming Roma Node Manager for the Southern Queensland and Northern New South Wales Innovation Hub. Lorinda joins our team with a wealth of experience in stakeholder engagement and community networking, working with government, non-government, community organisations, farmers, small businesses, and apprentices/trainees. “I’m all about connecting land managers and helping them understand how to become connected with innovation, upskilling, resilience, and cost-saving programs.” Lorinda Otto said. “My parents were farmers. Farming is in my blood and I have a passion for our environment. Outdoor experiences have helped shape who I am today.” Ms Otto said. “I was born in South Africa and I attended university in Johannesburg and initially started in the dental industry as an oral hygienist, but when we emigrated to Australia, I decided to be a stay at home mum for three years before later working at Queensland Health for nine months.” she said. “Following my work with Queensland Health, I worked briefly in the energy industry at Powerlink for 18 months which opened a door for me to work at Santos in their administration, community engagement, and data catchment fields.” “That opportunity led me into the government sector where I enjoyed five years in the Department of Employment, Small Business and Training, as their Senior Field Officer conducting key stakeholder engagement, supporting small business, and also monitoring the progression of apprentices and training programs,” Lorinda Otto said. “I worked across seven western shires, many of which are in SQ Landscapes’ catchment including Bulloo, Murweh, Ballone, Maranoa, Quilpie, and the Western Downs - alongside Banana and Blackall,” Ms Otto said. “I want our agricultural sector to be strong and healthy and I believe I have a role to play in that!” she said. Lorinda’s team includes Ally Southern, an Adoption Officer based in St George. They will work closely across the SQ Landscapes region to help land managers drought-proof their property and prepare for a more resilient industry. As the incoming Roma Node Manager, Lorinda will have lots on her plate, but she’s eager to rise to the challenge and bring her unique style to the role!
