Our Story
Biochar future: fixing climate change
Soil is one of the largest carbon sinks. Restoring soil carbon could offset (lock-down) 10-20% of ALL CO2 emissions. Every Kg of biochar added to soil permanently offsets ~2.4 Kg of CO2.
The technology to make biochar is available now. The storage method is IPCC approved. Verified track and trace systems exist for the purchase of biochar carbon removal certificates. The UK needs to add 1 million tonnes of biochar to UK soils to make a difference.

Who is SoilFixer?
Our vision is to produce high-quality soil enhancement products using locally sourced materials in a sustainable and ethical way.
SoilFixer was established by Tony Callaghan in 2016 to create ethically sourced soil additives free from fossil fuel-derived ingredients such as synthetic fertilizers. Recognizing the benefits of biochar in soil improvement, Tony developed many of his products around this sustainable material.
About Us
In March 2025, Brodie Biomass—a producer of high-quality biochar made exclusively from locally and ethically sourced wood chips—acquired SoilFixer.
Tony is working closely with Brodie Biomass to ensure a seamless transition and will continue to be involved with SoilFixer. However, after a decade of dedication to the project, he feels it is the right time to pass on the reins.
SoilFixer has relocated to Brockham, Surrey, and is now operated by a dedicated and passionate team led by Tom Brodie, who shares Tony’s passion for delivering top-quality products to gardeners and growers.
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.
