Compost activator

Add the organic compost activator regularly when setting up the compost heap (or, in the case of long-term composting without turning, when collecting). The better the mixture, the more effective the product—so don't apply thick layers, but mix it in as well as possible. The application rate should be around 10 percent by volume—i.e., 3 bags of organic compost activator for one cubic meter of compost source material.

This product contains stably bound, climate-effective carbon. This carbon has already been certified and compensated for in the form of CO2 certificates. Therefore, it is not possible to sell such certificates for this product.

With this new product, producing your own terra preta has never been easier—no more tedious searching for the individual additives you need; simply use the organic compost activator. Adding this product reduces nutrient loss during composting and leaves you with more compost of a higher quality. The right combination of rock flour and organic biochar also changes the microbiology during composting in the direction of Terra Preta biology. The finished compost and the black earth produced from it are able to bind atmospheric nitrogen more effectively, so that further fertilization of crops will no longer be necessary in the future.

Extensive research has revealed that three additives are required to produce highly fertile terra preta: biochar, rock flour, and the right microbiology for the composting process. These three additives have been mixed in the right proportions in the bio compost activator, making it easier than ever to produce your own terra preta!
