Stock Status In Stock

An excellent dry organic source of nutrients, including calcium (23%) and magnesium (1.33%).

It retains moisture in the soil and builds the organic matter. It also gives the roots something to grab onto and wrap around for a food source, creating a deeper root system.

Crab Shell is high in chitin (kite-en), which promotes the growth of chitin eating bacteria in the soil. It will help eliminate ants, grubs, fungus and root nematodes, because they are all chitin based in structure. Put around plants, Crab Shell will keep slugs and snails off. 4 lb bag.

Tested and proven with excellent results by many gardeners. Neptune's Harvest All Natural Organic Fertilizers and Amendments are OMRI listed for use in organic growing.
