About Carbon Gold Biochar®
Carbon Gold Biochar is a fine grade, highly porous enriched charcoal. Its large surface area enables higher volume of water and nutrient retention whilst the stable structure forms a home for microbiology to inhabit and multiply, helping to strengthen plants resistance to pests and diseases, for even better growing results.
Carbon Neutral Blend
During the biochar production process, large amounts of carbon gets locked into the biochar. By adding biochar to the compost at the optimal level, now makes compost carbon neutral*. By enriching with Carbon Gold, we are all doing our bit to create more sustainable gardens.
