Neptune's Harvest Organic Crab Shell is an excellent dry organic source of NPK, Calcium (23%) and Magnesium (1.33%). We recommend Crab Shell for nematode and fungus problems, to control Ants, Grubs, Fungus and weeds even weeds. Here's why: Crab Shell is high in Chitin (Kite-en), which promotes the growth of Chitin eating bacteria in the soil. helps control Ants, Grubs, Fungus and weeds.
The exoskeletons of fungus and nematode eggs are high in chitin. Use our crab shell to create a hostile environment for the fungus and nematodes by feeding the biological life that eats chitin and chitin based organisms.
Crab Shell can be applied with our Kelp Meal to increase organic matter and retain moisture in the soil.
