Do I need to add an activator to my compost pile?
It is not necessary to add an inoculant or activator to a compost pile. A compost pile should be composed of layers of plant material and soil or finished compost. The soil and finished compost contain the microbes that will decompose the plant material. When constructing a compost pile, also add some fertilizer or manure. Nitrogen accelerates the decomposition process if the plant materials are high in carbon.
