Oyster Shell

Oyster shell flour is almost entirely calcium carbonate. In addition it contains several other micronutrients. They provide a long-lasting, steady release of nutrients to help regulate pH levels, improve fertilizer uptake, promote healthy cellular structure and enhance soil tilth. Oyster shell also helps in the proliferation of beneficial soil microbes.
