We had two specific goals when we set out to create our Worm Power Liquid Extract. The first was that our liquid worm castings possess the same efficacy as our original worm casting vermicompost and the second was an extended shelf life. After years of research and product development we achieved both of our goals. The microbial activity in Worm Power maintains its viability because we do not promote excessive population growth in our production process. We use what is referred to as a “non-aerated extraction” method which enables us to gently extract the fertility components and microbes from the solid worm castings and vermicompost into liquid form. Because we purposefully do not induce artificially high “blooms”, the microbes present in Worm Power have enough oxygen and “food” to sustain their viability in the bottle for up to two years.
