Biologic Systems Worm Castings

Worms process the essential nutrients and trace minerals found in soil, removing pathogens and making them easily accessible to plants. 100% organic and of unparalleled quality, these castings contain a diverse array of beneficial bacteria, fungi, and other microbes that assist in plant nutrient uptake and build soil structure. With the highest microbial count we’ve analyzed, this is an outstanding input for compost teas/extracts, soil amending, top dressing, soil rejuvenation, etc.
