Oyster shell flour 1/2lb

Oyster shell meal is beneficial to the vermicomposter for several reasons. Compound at 96% calcium carbonate and numerous micronutrients, oyster shell provides a steady, long-lasting release of nutrients to help regulate pH levels to create more active habitats for soil microbes in compost piles and worm bins.

Calcium plays a very important role in the reproduction of earthworms, so you may also see an increase in reproduction when used regularly.
