Organic Solution’s Natural Crab shell is an incredible natural source of Calcium (23%)
and Magnesium (1.33%). The Chitin in the Crab shell stimulates soil organisms causing
them to secrete enzymes called chitinases. These enzymes degrade chitin, which in turn
makes it a natural biopesticide that is non-toxic! Adding Crab shell to your soil will also
protect from bad nematode and fungus problems alike.
