According to the USDA Natural Resources Conservation Service, worms digest the plant material they ingest and concentrate the nutrients in their castings. Their castings are extremely rich in phosphorus, nitrogen, potassium, and magnesium.
They also contain live organisms, like actinomycetes, fungi, pseudomonads, beneficial bacteria, yeasts, plant growth regulators, molds, and trace elements. All these elements work together to create a favorable environment for plants and stimulate their growth.
Our worm casting Soil Builder is safe to use in any quantity. Your children or pets can safely play in the garden, and you can safely store it your garage, basement, or garden shed, without worrying about unpleasant smells or pest invasions.
