Title

Oyster Shell Flour (Replacement for Dolomite Lime)

Oyster Shell Flour is a high quality soil conditioner which consists of 96% calcium carbonate and many micronutrients, Oyster Shell Flour provides 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 is also helpful in creating more active habitats for soil microbes in compost piles and worm bins.

This product is not what it would appear from the name, i.e. it's not a product made from crushed oyster shells but rather it's a particular oyster shell mined from the San Francisco Bay from ancient sea deposits made up of very tiny and fragile oyster shells.

Oyster shell for all

All plants love this amendment. Blossom end rot? Not with oyster shell and healthy soil and soil life helping to break down and make available for uptake.
