Neptune's Harvest Organic Crab Shell (2 - 3 - 0) is an excellent dry organic source of NPK, 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 helps to rid your garden of nematode and fungus issues. Here's why: Ants, Grubs, Fungus and Root Nematodes are all Chitin based in structure. Crab Shell is high in Chitin, which promotes the growth of Chitin eating bacteria in the soil. The exoskeletons of fungus and nematode eggs are high in chitin. When added to the soil crab shell helps to create a hostile environment for the fungus and nematodes by feeding the biological life that eats chitin and chitin based organisms.
Put around plants, Crab Shell will keep Slugs off. It also helps choke out weeds (weeds hate Calcium). Crab Shell should be worked in the soil before planting, or top dressed. It can also be applied to lawns with a broadcast spreader for amazing results on lawns and all plants!
