Unlocking the
value in your pasture & soil.
Agrimix Flux is a decision toolkit turning grazing science and on-farm data into paddock-level guidance – as conditions change, not months or years later. Once you can measure and model your pasture and soil, you can build value in it, and prove it.
Paddock-level soil carbon modelling for Australian grazing systems, calibrated with flux tower data
The challenge
Australia's producers are managing more than just their paddocks
Australian producers are facing more challenges than ever, with pasture rundown, dieback, groundcover pressure, changing climatic conditions and a growing need to demonstrate sustainability outcomes to the supply chain. Pasture decisions come at a cost – when to spell, when to restock, where to invest in pasture improvement need to be made with confidence.
Introducing Agrimix Flux
From research to real value on farm.
Since 2008, Agrimix has partnered with Australia’s top researchers and farmers to turn science into solutions. Agrimix Flux is one of the groundbreaking outputs of that work – a decision toolkit connecting pasture management with productivity and soil carbon outcomes in one platform.
Agrimix Flux is built on DayCent-CABBI, a process model of how carbon and nitrogen move through soil and plants. We calibrate it with data from our network of 10 eddy covariance flux towers on grazing properties in Queensland and New South Wales, which measure the CO2 a pasture takes in and releases.
The method was calibrated in the Brigalow Belt, validated at independent sites in NSW and published in peer-reviewed literature (Takeda et al., 2025). The work was built with Meat & Livestock Australia and Queensland University of Technology.
Our Measure Model Verify (MMV) approach links paddock management to soil carbon and productivity outcomes. Producers can see how a season, a grazing decision or a pasture change is likely to show up in their soil, and plan accordingly.
Science, Integrity, Results.
Built with MLA & QUT. Tested under Australian grazing conditions. Published in peer-reviewed literature.
How it works
Taking control of your livestock business.
Agrimix Flux helps you target the right paddocks at the right time, then test options with “what-if” scenarios, like Progardes® Desmanthus plantings or alternative grazing strategies, before you spend the money.
1
Track pasture performance by paddock
A paddock-by-paddock read on productivity, cover and condition, modelled from your property’s own data rather than regional averages.
2
Protect land condition and productivity
Spot issues early. Improved pasture research shows deep tap-rooted legumes and time-controlled grazing can increase soil carbon. Use that insight before condition declines.
3
Make earlier, more confident decisions
Paddock-level guidance from grazing science and on-farm data, updated through the season.
Results from the field
Real producers, real paddocks, real results.

Who it’s for
Built for producers. Valuable for any industry that needs to prove its carbon story starts on the farm.
Agrimix Flux delivers different value depending on where you sit — in the paddock, in the supply chain, or to support consumers wanting to know the data and story about the products are real.
Red Meat Producers
Better decisions for more profitable and resilient beef businesses.
Track what’s happening in your paddocks, protect land condition, and make grazing calls with confidence — backed by science, not guesswork.
- Paddock-level pasture performance tracking
- “What-if” grazing scenario modelling before you spend
- Soil carbon monitoring integrated with day-to-day management
- Traceable soil carbon records your supply chain can report against
- Progardes® Desmanthus integration for improved pasture outcomes
Supply Chain Buyers
Turning climate reporting requirements into supply chain opportunity.
Industry
One rigorous approach, multiple land management applications.
The Agrimix Flux methodology can be applied to any paddock — bringing the same paddock-level carbon and productivity insights to industries like fine wool producers to biofuels to rice production.
- Pasture performance tracking adapted for wool grazing systems
- Soil carbon monitoring and reporting for biofuel feedstocks
- Evidence base for sustainability claims in fibre markets
For supply chains
Grazing soil carbon data your reporting team can stand behind
If your business buys beef or wool, part of your emissions footprint sits on the properties you source from. When you report soil carbon removals against that footprint, or make a product claim, you need to show where each figure came from and why it changed.
Agrimix Flux gives you a property-level soil carbon record, built paddock by paddock from the producer’s own management data and calibrated against flux tower measurements. The producer manages to it, your assessor interprets it, and your team reports against it.
What you get
- Annual soil carbon stock change for each property, modelled to 30 cm
- The drivers behind each change, such as rainfall, grazing pressure or pasture renovation
- A documented method, published in peer-reviewed literature, that your assessor or verifier can review
- The same dataset your producers use for grazing decisions and, where they choose, ACCU projects
Working with your carbon assessor
We work alongside the carbon assessors and advisers who already prepare your supply chain’s footprints. Agrimix Flux supplies the soil carbon data; they bring it into the property or product assessment.

FAQ
Common questions.
What is Agrimix Flux?
Agrimix Flux is a decision-support toolkit that helps landholders, project developers and supply chains understand how pasture management decisions influence productivity and soil carbon outcomes. It uses a three-step Measure, Model and Verify approach, combining field data from flux towers with ecosystem process modelling to quantify soil carbon change at paddock level. Agrimix Flux can supply soil carbon data for ACCU projects, insetting and supply chain emissions reporting, including Scope 3 data requests from companies reporting under AASB S2.
Is Agrimix Flux available now?
Yes — Agrimix Flux is live and currently being used on properties across Northern Australia. Contact the team for a demo.
What is a flux tower and how does it work?
A flux tower is a field-based monitoring system that continuously measures the exchange of gases, energy and water between the land surface and the atmosphere, helping researchers understand whether a paddock, pasture or ecosystem is taking up more carbon than it releases. Using a method called eddy covariance, flux towers provide real-world data on carbon dioxide movement, plant growth, soil respiration and water use over time. Agrimix uses flux tower data to calibrate and validate its soil carbon model for Australian grazing systems, including management practices such as Progardes Desmanthus, so our modelling reflects what is actually happening in Australian paddocks.
What properties and regions is Agrimix Flux suited to?
Agrimix Flux is currently calibrated and validated for the Brigalow bioregion, making it well suited to grazing properties in that region that want to monitor soil carbon, pasture productivity and the impact of management decisions over time. Next, Agrimix will be validating Flux in New South Wales. The toolkit is suited to landholders and organisations wanting robust evidence of carbon and productivity outcomes, whether for a registered Clean Energy Regulator soil carbon project, supply chain reporting, insetting, or general productivity monitoring and decision-making.
Can Agrimix Flux generate carbon credits?
Agrimix Flux is designed for generating Australian Carbon Credit Units (ACCUs) and is also suited to the voluntary carbon schemes (E.g., Verra). It produces traceable, audit-ready evidence of soil carbon stock change at paddock level. Speak with the team about how this applies to your business.
How does Agrimix Flux relate to Progardes® Desmanthus?
Agrimix Flux is directly linked to Agrimix’s research into Progardes® Desmanthus and its ability to sequester soil carbon in Australian grazing systems. Using on-farm data, flux tower measurements and ecosystem process modelling, the toolkit provides the first soil carbon model calibrated for Progardes Desmanthus plantings. This helps landholders understand how Progardes may contribute to soil carbon outcomes, pasture productivity and long-term grazing system performance.
Is Agrimix Flux available for wool producers?
Yes. Agrimix Flux is being extended for wool producers through Agrimix’s project with Australian Wool Innovation, supporting the development and validation of the toolkit for grazing systems relevant to the wool industry. Agrimix Flux is designed for producers who want to monitor soil carbon, pasture productivity and the impact of management decisions over time, whether for productivity insights, supply chain evidence, insetting, or carbon project purposes. The toolkit is currently calibrated and validated for the Brigalow bioregion, with the next stage focused on validation in New South Wales, including systems relevant to wool-growing enterprises.
