If fulvic acid is so important, why haven I heard of it before?
Outside of technical circles, fulvic acid is virtually unknown. In plants, fulvic acid stimulates metabolism, provides respiration, increases metabolism of proteins and activity of multiple enzymes, enhances the permeability of cell membranes, cell division and elongation, aids chlorophyll synthesis, drought tolerance, crop yields, buffers soil pH, assists denitrification by microbes, contributes to electrochemical balance as a donor or an acceptor, decomposes silica to release essential mineral nutrients, detoxifies pollutants such as pesticides and herbicides.
