Our research
We research grower innovations that
build soil carbon and reduce emissions
We measure and validate carbon farming systems and practices through the three lenses of economic viability, soil carbon and emissions reduction science and adoptability. Our research is impactful, collaborative, resourceful, feasible, and ethical.
We conduct high-impact research to solve real-world problems by addressing knowledge gaps and contributing to the existing agricultural soil carbon evidence base.
At SoilCQuest 2031, we believe everyone has a role to play in research. Co-designed research is an iterative and dynamic process between researchers and farmers.
By collaborating with farmers, academia, industry and government, we support and enable research and the translation and integration of research across all sectors.
Strategic research
SoilCQuest Research Strategy
Our three-year Research Strategy 2024-2026 is informed by two research goals:
- Increase the adoption of scientifically validated and economically viable farming practices that build soil carbon.
- Support farmer innovation, scientifically validate their practices, and promote widespread adoption.
Increasing photosynthetic carbon inputs and reducing soil carbon loss are vital pathways to turning around Australia’s soil carbon stocks, which have declined due to historic agricultural practices. SoilCQuest researches methods within these pathways in broadacre agriculture, including cropping and pasture systems. Our research themes (below) address one or both of these soil carbon sequestration pathways:
- Amelioration of under-performing soils
- Increase plant species diversity in cropping and pastures
- Increase the use of perennial plants in agricultural landscapes
- ‘Connecting the dots’ – finding efficiencies and synergies
- Biomass conversion for biochar production
- Building soil carbon via bigger root systems.
SoilCQuest is unique in working with farmers directly using co-design approaches to provide unbiased information that contextualises agricultural research within a commercial environment.
Our primary objective is to address farmers’ needs which guides our experimental research designs. While we focus on practical outcomes rather than academic publications, we strive to design research projects that allow valid statistical analysis.
Our strategy also aligns with the ACCU Scheme and embraces state-of-the-art research and digital and remote-sensing tools.
SoilCQuest seeks to scale up the adoption of our findings by prioritising applied research directly on commercially viable farms rather than in controlled lab or greenhouse settings. As such, our research methodology is informed by Paddock Scale Research.
On-farm research
trials with growers
SoilCQuest 2031 brings research to the paddock to support big and small farming operations to build soil carbon for resilience and productivity. Our approach focuses on capacity-building in farmers through accessible communication of research findings and providing pathways for them to explore and adopt soil carbon-building practices.
In 2024, SoilCQuest’s research portfolio includes:
- Evaluating the effects of granulated compost on grain yield, soil carbon, and soil health indicators in a broadacre system.
- Testing whether applications of foliar urea can improve nitrogen (N) use efficiency in canola (with potential benefits in reducing ammonia NH3 and nitrous oxide N20 emissions associated with urea use).
- A case study on whether time-controlled cell grazing can significantly enhance the soil restorative effects of multi-species cover crops compared to set stock grazing.
- A laboratory study to assess current products and compounds that show efficacy in stimulating plant root growth, with the aim to find a product or compound that could, in dry powder form at planting time, enhance the root growth of cereal crops (leading to downstream benefits for soil carbon sequestration).
- Multi-graze, an applied research project, a collaborative effort between SoilCQuest and farmers that focuses on paddock-scale trials to document the agronomic and economic impact of implementing climate-smart agricultural practices.
Impact of Intercropping and Biofertilisers in a 2-Year Field Trial in North-Central Victoria
In 2019-2020, SoilCQuest, Grant Sims, and Kalyx conducted a field experiment to assess soil carbon changes and crop yields in intercropping versus monoculture systems, comparing the effects of biofertiliser and synthetic fertilisers over a 2-year rotation. The study also evaluated the economic benefits of using farm-made biofertilisers in intercropping compared to monoculture with mineral fertilisers.
Down to Earth: Estimating Carbon Stocks with Remote Sensing Tools
SoilCQuest 2031 and Downforce Technologies partnered in a research project to test Downforce’s software for estimating soil organic carbon percentages (SOC%) under different farm management practices. Downforce Technologies is ISO 14064-2 certified, making it the first company globally to offer ISO-certified remote soil organic carbon measurement and land management assessments.
