Southwestern Queensland Trial Farm Project

Our trial farm in southwestern Queensland presents a unique set of challenges that demand innovative and tailored solutions. The land is characterised by near-surface rocks, which significantly hinder conventional farming techniques, making the soil difficult to cultivate and limiting its agricultural potential. Additionally, the farm is overrun with an invasive grass species that poses a dual threat: it acts as a major fire risk during dry seasons and reduces overall farm productivity by competing with desirable crops for resources. These factors combine to make traditional farming methods ineffective, necessitating a forward-thinking and regenerative approach to unlock the farm’s full potential.

This project is specifically designed to address these challenges while focusing on improving the farm’s soil health, carbon content, and overall resilience. By adopting regenerative agriculture techniques, we are introducing crops that not only thrive in challenging conditions but also provide substantial benefits to the soil. High-biomass crops—preferably nitrogen-fixing species—are being strategically planted to enhance soil organic matter, increase carbon sequestration, and establish a biodynamic soil structure that can support long-term agricultural productivity. These species are carefully selected to combat soil degradation, improve fertility, and create a more resilient farming ecosystem.

Initial trials have already yielded promising results, demonstrating the farm’s potential for transformation. Early data indicates that with proper management and regenerative practices, it is possible to add up to 25mm of new biodynamic soil cover within a single year. This accelerated improvement in soil depth and quality not only enhances the farm’s productivity but also lays the foundation for long-term sustainability and climate resilience. By addressing these unique challenges head-on, this project is setting the stage for a model of farming that balances productivity with ecological integrity.

Key Activities

  1. Soil Carbon Enhancement

    • Crop Selection: Planting high-biomass, nitrogen-fixing crops that maximise carbon sequestration and organic matter accumulation.
    • Soil Cover Development: Implementing regenerative practices to add an estimated 25mm of biodynamic soil annually.
    • Soil Monitoring: Regularly testing soil carbon levels and structure to refine techniques and optimise results.
  2. Invasive Grass Removal

    • Fire Risk Mitigation: Removing tough invasive grass species to reduce fire hazards and protect farm productivity.
    • Biodiversity Improvement: Replacing invasive grasses with native or sustainable species that contribute to the farm’s ecosystem health.
  3. Biodynamic Soil Building

    • Enhancing Soil Dynamics: Addressing near-surface rocks by improving the topsoil’s quality and depth to create more arable land.
    • Testing New Techniques: Experimenting with different biodynamic practices to maximise soil health and long-term productivity.
  4. Data Collection and Analysis

    • Measuring biomass yield, soil carbon increase, and invasive species eradication rates.
    • Monitoring fire risk reduction and overall ecosystem improvements.

Expected Outcomes

  • Soil Carbon Increase: Achieve significant annual increases in soil carbon content, with 25mm of additional cover annually.
  • Enhanced Land Productivity: Improve soil structure and fertility, making the land more suitable for farming despite surface rock challenges.
  • Fire Risk Reduction: Eradicate invasive grass species, reducing fire hazards and protecting long-term farm sustainability.
  • Ecosystem Restoration: Establish a more biodiverse and resilient farming environment that supports long-term productivity.

Project Impact

This project highlights Sequestra’s commitment to tackling unconventional farming challenges with innovative, science-backed solutions. By focusing on soil health, carbon sequestration, and ecological balance, this trial farm sets a benchmark for how degraded or difficult farmland can be transformed into a thriving, sustainable carbon sink. The results of this project will serve as a blueprint for similar initiatives in challenging agricultural landscapes.

“At Sequestra, we’re not just improving the land—we’re building the future of sustainable farming.”
