Fulvic & Humic Acids
Humus is a vital, yet small (2% by volume) part of healthy soil. It differs from organic matter in that humus has undergone humification - a process by which decomposed organic matter is reconstituted to form complex organic molecules that serve different purposes in the soil. These humic substances include humic acids, humin and fulvic acids.
