Pure, Lab-tested Earthworm Castings (No Fillers Added)
What are Castings? Earthworm castings are the nutrient-rich by-product earthworms produce after eating. Castings are a natural, non-toxic soil fertilizer full of beneficial plant nutrients like nitrogen. Castings significantly enhance plant growth and minimize plant disease and are coveted by the vineyard and cannabis industries, organic farms, and many others.
Our Castings: We use a standard approach to ensure a consistent, pure, and high quality end product. Unlike many castings producers, we do not add fillers so our castings offer greater benefits at lower application rates.
Lab-Tested: We routinely test our castings with an independent, national lab that specializes in soil biology. The results show castings high in soluble salts, essential nutrients, and beneficial fungal and bacterial feeders.
