By providing existing soil microbes with food and energy, crab meal naturally and safely improves soil health by enhancing the beneficial microbial community in the soil so plants can thrive. The key ingredient is naturally derived crustacean meal. Scientifically proven to stimulate the soil microbiome, particularly microbes associated with the biological control of plant pathogens and parasitic nematodes, crustacean meal improves soil health for greater root and plant vitality. Adding crab shell to an existing production program increases nutrient uptake and root development, for increased resistance to stress and maximum crop yield across various growing locations and soil types.
