In addition to being delicious, crabs can also be a great addition to your garden or farm. Crab Shell Flour is derived from scrap shells and is incredibly sustainable. This is a fantastic dry natural plant food that provides essential nutrients that plants need to thrive.

Crab shells help support a healthy microbiome by adding higher calcium levels to the soil. Crab shells are naturally high in calcium and chitin. Chitin encourages bacterial growth. In addition, pests like ants, grubs, and nematodes have exoskeletons high in chitin, so introducing a fertilizer that fuels organisms that feed off the substance will create an environment that helps keep these pests at bay.

You can incorporate the Crab Shell Flour into the soil or use it as a top dressing around plants.

I have a greenhouse that unfortunately does not get the ideal sunlight due to its location on the north side of my home. I have been using Rocky Mountain BioAg’s Quantum Growth Organic Total for over a year and have seen a dramatic increase in plant growth and vegetable yield compared to past years. Highly recommend the product.
