Neptune's Harvest Crab Shell 4 lb Bag Microbe Life Works well with all nutrientNeptunes Harvest Organic Crab Shell (2 3 0) is an excellent dry organic source of nutrients, including Calcium and Magnesium. It retains moisture in the soil and builds the organic matter. Gives roots something to grab onto, for a food source, creating a deeper root system. Crab Shell is high in Chitin (Kite en), promoting growth of Chitin eating bacteria in soil. Helps eliminate Ants, Grubs, Fungus and Root Nematodes (all Chitin based in structure).
