Made from 100% Blue Crab with no other additives. Crab shell is an excellent source of NPK, Calcium, (18%) and micro nutrients. The high levels of chitin in crab shell creates a perfect feeding ground for chitin eating bacteria; thereby increasing the bacteria's population. These bacteria in turn feed on the chitin containing cell walls of nematodes and fungi present in the soil. The increased presence of chitin in the soil also triggers a defense response in the plant causing a release of chitin destroying enzymes, thus increasing the plants' defense mechanisms and immune response. In this way, the crab shell inadvertently creates a hostile environment for nematodes and fungi and strengthens plants.
Crab Shell can be applied with our Kelp Meal to increase organic matter and retain moisture in the soil.
