This Biochar is made from the same material as our Biochar and Horticultural Char. It is the ultra fine particles that are gathered through the screening process. Fine enough for the worms to eat and to to spread as a top dressing and watered in. Won’t take long for the microbes, water and nutrient to permeate it pores. With an already immaculate surface area, electromagnetic charge and 80% carbon content, you will notice the difference when improving your soil.
