Biochar Products To Regenerate Degraded Soils & Increase Plant Resiliency


Carbon Gold develops and promotes the use of biochar in arboriculture, forestry, agriculture and turf management. By rebuilding degraded soils, sequestering carbon in soil and wood, and optimizing soil biology, biochar (ground charcoal from woody biomass) helps to reverse climate change and provides fertile soils for future generations.

Research has shown that biochar can help to regenerate degraded soils and prevent the spread of pathogens - both airborne and soilborne, increasing the health and resilience of crops.  Using biochar can help the agriculture industry combat climate change and rebuild soil’s organic carbon without the use of potentially harmful fertilizers.

Founded in 2008, Carbon Gold is a pioneer in the biochar industry. We have a suite of products for trees, turf and horticulture that are proven in effectiveness. More and more producers and arboriculturalists are using biochar in place of chemical fertilizers and fungicides that degrade soil and lead to soil erosion and desertification.

As a company, we support land remediation, the use of wood in place of steel and concrete in buildings, and the afforestation of deforested land.


Carbon Gold was founded to help mitigate climate change and support sustainable food production with the use of biochar. Biochar-based products removes carbon dioxide from the atmosphere and improve soil fertility by returning essential nutrients back to the earth without the use of harsh fertilizers. Increasing fertility of arable land supports international efforts to cut energy consumption, reduce greenhouse gas emissions and removes the needs for aggressive and destructive farming practices that lead to deforestation and the destruction of natural ecosystems.

Ending the global reliance on chemical fertilizers and fungicides is Carbon Gold’s aim: reversing soil destruction caused by harmful chemicals enables people to grow the food they need to survive, and empowers communities to develop their own crop-based economies without further harm to the environment.

Carbon Gold works with home growers, NGOs and community cooperatives, and has worked with some of the world’s major food brands, including Mars, Nestle and Kraft. Some of its tree care products are used in the Royal Parks and Gardens of the UK.


Biochar is a highly porous, high carbon form of charcoal used to improve soil nutrition, growing conditions and soil structure. It is made from untreated waste woody biomass that has been charred at a low temperature with a restricted supply of oxygen - a process called pyrolysis. The result is a stable form of carbon that is removed from the atmospheric carbon cycle when added as a soil amendment: one tonne of carbon contained in biochar represents three tonnes of CO2e equivalent being removed from the atmosphere, saving up to two tonnes of emissions.

The microscopic honeycomb-like structure of biochar allows beneficial microorganisms, such as mycorrhizal fungi and actinomycetes bacteria, to flourish. Acting like a sponge, biochar helps with water retention, reducing the need for complex irrigation and improves drought resilience. Its sponge-like nature also captures mineral nutrients that would otherwise be leached away by rain, and is stable: Biochar can remain in soil for 50-600 years.

Biochar has been used for millennia. Evidence of this can be found in the Amazon Basin, where studies of soil at ancient agricultural sites suggest that the Indigenous people made a primitive form of biochar to help grow their food. The resulting fertile black earth is still evident today.
