Working with farmers to transform agriculture and rebuild health
About CircleAG
CircleAG is a specialised Australian liquid biofertiliser company helping farmers rebuild soil health, lift yields and improve long-term profitability.
Healthier soils mean stronger crops, better nutrient uptake, improved water retention and more resilient farming systems – without adding complexity or extra cost. CircleAG is designed for real farms, real conditions and multiple scales – from IBC to 53,000 litre A-Double loads.
What we offer
One complete liquid solution CircleAG has created a fully integrated biological and nutritional fertiliser at scale. It combines minerals, microbes, and plant vitamins in one liquid product to feed crops, strengthen plant health, and restore living soil.
No 'green premium' CircleAG is priced at parity with conventional synthetic fertilisers. Farmers don't pay extra to improve soil health - regenerative outcomes are built into the product.
Easy to use CircleAG integrates with most existing spray and fertigation equipment. It fits into standard farm practices, so adoption is straightforward and practical.
Ready for scale With a 2.6-million-litre manufacturing facility in Central Victoria, CircleAG has immediate production capacity. We are expanding nationally, with our next facility currently under development in the WA Wheatbelt, building reliable supply as demand grows.
The CircleAG advantage
CircleAG regenerates living soils to drive a range of material on- and off-farm outcomes, including:
Carbon Builds soil carbon and supports stronger plant growth, helping lock more carbon into the land at scale.
Water Improves soil structure so it holds more water, helping crops cope better in dry conditions.
Health Grows more nutritious crops, with flow-on benefits for human health and wellbeing.
Nature Restores living soils, supporting healthier ecosystems and more resilient landscapes.
Community Uses a locally made, scalable production model that supports regional jobs and local economies.
Our results
Our system has been tested across more than 9,500 hectares over 5+ years. Trials and commercial use span broadacre cropping, grazing systems, horticulture and environmental plantings.
The results* from our trials have been very strong – and we’re committed to supporting farmers to achieve the best possible outcomes on their own land.

Measurement and verification
We use a range of proven tools to verify our results, including:
High-precision remote sensing and digital modelling
Federally approved soil carbon measurement methods
Advanced soil and biological testing, including Haney and PLFA analysis
We also partner with leading academic institutions to strengthen the rigour of our testing and interpretation of results. Together, these tools help ensure our results are accurate, repeatable and independently reported.
Who we work with
CircleAG works alongside broadacre producers, organic and regenerative farmers, and investors who are committed to long‑term land health and productivity.
We have partnered with Australian investment manager Tiverton Global, supporting an integrated approach to soil health, ecosystem recovery and farm performance across their agricultural portfolio.
