Fulvic acid has a biological activity to promote the growth of plant. But it is a problem that fulvic acid is present in only a small amount in soils or low lank coals. It was shown clarified that weathered coal could produce the fulvic acid-like substance using hot compressed water in a semi-batch reactor below 270℃. These products was similar to practical fulvic acid extracted from weathered coal in the chemical structure.
