CSIRO and ten partner organisations just kicked off a five-year trial testing regenerative farming practices across South Australia, Victoria and New South Wales. It isn't about whether regenerative farming sounds nice on a label. It's about whether it actually holds up in Australian dirt, under Australian rainfall, over five full growing seasons.
What's actually being tested
The project is called STRAP, short for Stress Testing Regenerative Agriculture Practices, and it's farmer-led from the ground up. The research questions came directly from grain growers through local farming systems groups, coordinated at a regional scale by the Ag Excellence Alliance. On trial: intercropping, using legumes as a nitrogen source instead of synthetic fertiliser, alternative fertilisers, and integrating pasture into cropping systems. Small-plot experiments across the three states will be analysed together as one multi-environment study, backed up by four larger demonstration trials, plus new soil health and resilience tests and an assessment of what each practice actually costs and saves.
Why "it worked overseas" isn't good enough here
CSIRO's Dr Mark Farrell makes the point that regenerative practices proven in Europe or the Americas don't automatically transfer to Australian paddocks. Our soils are older and more weathered, and our rainfall is far more variable, so the evidence base has to be built locally rather than borrowed. Australian soil has never been especially interested in instructions written somewhere else, and this time CSIRO is making sure the evidence is actually ours. Nearly $8 million from the federal Future Drought Fund is going into the project, run with ten partner organisations including Mallee Sustainable Farming. Dr Penny Roberts from that group says growers want systems with year-round ground cover that stay economically viable and resilient when moisture is limited, which is a fairly precise description of the whole point of farming in this country. CSIRO is also building data systems linked to AI and geospatial platforms to track greenhouse gas emissions, input use and economic risk at scale as the trial runs.
What this has to do with what's in your bathroom
Every plant-based formula starts somewhere in soil like this, long before it becomes an ingredient on a label. Work like STRAP is exactly the unglamorous, multi-year groundwork that decides whether "natural" and "plant-based" claims can actually be backed up season after season, not just when conditions are kind. It's also a reminder that the ingredient story doesn't start with the brand, it starts with the grower and the paddock, which is a big part of why we care about what actually goes into a shampoo bar, and what doesn't. For more on how CSIRO's been busy lately, we also covered their honeybee silk wound dressing breakthrough.

Nearly $8 million and five years, just to find out which farming tricks actually work. We'd call that thorough. Australian soil would probably just call it overdue.
