Oyster Shell Flour A high quality soil conditioner which consists of 96% calcium carbonate and many micronutrients, Oyster Shell 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.

The product arrived in good shape and it was just as listed. Another 100 pounds will probably be needed soon and I won't hesitate to order from Build a
soil.
This is being used to condition my backyard Bocce court.
Really looking forward to using this. It’s a great source of minerals and Ca for your plants.
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.
This is very fine, as the name says, so just take precaution for the airborne particles. I havent checked the ph of my soil yet as it is just about finished. I'm certain it will be good. I followed a very complete recipe that is true and true since the 30s. Shout out to Coot!
