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 chip—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.
