SoilFixer Compost Activator (Humification Agent)

SoilFixer Compost Humification Agent is a compost activator that boosts microbial activity and speeds up decomposition. It contains biochar granules, trace minerals, and composting microbes to increase humus formation from under 5% to as much as 40%. The biochar improves airflow, reduces odours, and captures nutrients for slow release. Perfect for gardeners wanting richer, more fertile compost and Terra Preta-style soil.

Make your own super compost containing higher levels of colloidal humus and biochar.
