Oyster Shell Flour: in addition to a large percentage of calcium carbonate, Oyster shell flour contains about 1-% phosphoric acid, which makes oyster shell flour a source of both lime (calcium) and phosphorus. Oyster shell will also slightly raise your soils PH over time.
What is the pH of oyster shells?

Are oyster shells good for soil?
Oyster shells are composed of primarily calcium carbonate (aka chalk), which can help buffer soil acidity and provide plants and microbes with vital calcium. Plus, the texture of the oyster shell helps prevent soil compaction which can improve aeration.
Do oyster shells make good fertilizer?
The addition of oyster shell mulch improves chemical balance in the soil, adds many nutrients, and improves water penetration. Calcium in the soil promotes a bigger root system, often leading to larger top growth on foliage and flowers.

Is lime made from oyster shells?
Shells from oysters, mussels, scallops, whelks, crabs and lobsters can all be processed into building lime.
Are oyster shells alkaline?
Oyster shell can be used as an alternative to lime. Both are composed of calcium carbonate, which is an alkali, and therefore raises the pH of the soil, increasing the plant’s ability to take up other micronutrients such as zinc, iron and manganese.

Why is my worms turning white?
White worms themselves are completely harmless in a worm bin, but again they may be and indication that you are overfeeding, or perhaps adding too much acidic waste.
Why are some oyster shells black?
The makeup of an oyster shell is over 90% calcium carbonate.
Just like us, the melanin in their shells reacts similar to human skin when exposed to the sun: it burns. Some oysters have black stripes or are almost black due to prolonged sun exposure.
What can you do with old sea shells?

Can you put seashells in compost?
Shellfish shells can be composted but will break down very slowly unless they are crushed into smaller pieces or ground into a meal. At the same time, they are also a rich source of calcium and important plant micronutrients, and can therefore make a valuable and sustainable amendment to the home garden.
