Black Worm Castings 40 lb
A little goes a long way! Mother Nature's finest castings provides the essential NPK. Bio-humus provides organic matter (humate), which retains water and the humic acid that enhances soil nutrient availability.Worm Castings are an all purpose natural fertilizer with no alterations whatsoever. Our earthworms live in nutrient rich bedding material which they process and digest. During the digestion process, the earthworms beneficially alter the material chemically and physically. The end product is a rich, dark humus material that is extremely fertile and readily available to the plants. The worms' digestive system also adds beneficial microbes to the worm castings to help create a "living" soil environment for plants.
