For the extraction of humic, fulvic, and himatomelanic acid, I use leonardite as raw material, and I perform the extractions through alkaline hydrolysis; I also do it with bio-fermented materials. A 25kg bag of leonardite costs about $25, and I can produce enough product to nourish 4 hectares. For the basic formula, I only need: a barrel, leonardite, pure water, and KOH. I have several formulations where, in addition to leonardite as the main element, I add other minerals and organic components; the resulting product is excellent, and I use it in different phases of my crops. Follow my organic diaries, I have tips on how to make all kinds of organic preparations. Cheers!
