Our Story
Who Is SoilFixer?
SoilFixer began with a simple belief: better soil means better gardens.
Many gardeners struggle with tired, compacted, or nutrient-poor ground — and traditional solutions often rely on peat or chemicals that offer only short-term fixes.
In 2016, lifelong soil enthusiast Tony Callaghan set out to create products that were kinder to both soil and the environment. His goal was to develop peat-free, sustainable soil improvers that help gardeners grow stronger plants, healthier lawns, and more productive vegetables.
Inspired by the unique benefits of biochar, Tony built many of SoilFixer’s products around this natural material — known for improving water retention, boosting soil life, and locking in nutrients.
The result is a range of soil improvers that are not only good for your plants, but also good for the planet — locking carbon into the ground permanently.
About Us
In March 2025, SoilFixer entered an exciting new chapter when it was acquired by Brodie Biomass, a specialist producer of high-quality biochar made exclusively from locally and ethically sourced wood.
Founder Tony Callaghan continues to work closely with the Brodie Biomass team to ensure a smooth transition and remains actively involved with SoilFixer. After more than a decade of dedication, Tony felt the time was right to hand over the reins — confident that SoilFixer would continue to thrive in capable hands.
Now based in Brockham, Surrey, SoilFixer is led by Tom Brodie, who shares Tony’s commitment to innovation, sustainability, and delivering top-quality soil improvers for gardeners and growers.
With a passionate new team and Brodie Biomass’s expertise, SoilFixer is perfectly placed to keep helping people create healthier, more productive soils.
Sustainability Commitment
Sustainable Products
Every 1 Kg of our biochar offsets (locks) approximately 3 Kg of carbon dioxide from the atmosphere.
All our products contain biochar, which not only helps improve soil health and fertility but also plays a crucial role in reducing your carbon footprint by sequestering carbon in the soil for the long term.
Sustainable Business
Our immediate goal is to ensure our business is sustainable and carbon neutral.
We dislike ‘green washing’ – we know we still have work to improve how we produce, transport, package, and supply biochar. We have a path forward and our long-term goal is a carbon negative business model.
