Vermicomposting and microbial composting are two separate process of making compost. Vermicomposting is carried out by earthworms that feed on complex organic matter and excrete out simple organic matter which enriches this soil. Our specially selected enzyme producing microbes accelerate the further degradation of this relatively simple organic matter in bioavailable form for plants to use. So to answer your question, SoilMate may not have a direct impact on the first stage of the vermicomposting process, but it will prove very useful in accelerating the second part of the process I.e. enriching your compost by increasing the bioavailable nutrients.
