CORRECTION (apologies): 25 percent pure liquid fulvic would be near impossible to achieve. (Again this illustrates my point about differences between dry and wet weight measurements.) Typically the highest possible liquid concentration using proper content-analysis is around 15 or 20 percent. The $7,000 figure is for a solution with 25 HUMIC acid/2-3 percent fulvic.
"Please beware of anyone claiming unreasonable concentrations of liquid fulvic acid. While near impossible a LIQUID 90% fulvic acid will be thicker than cold molasses and you would only need a pin head as a dose. Often this percentage is in reference to the parent material, or raw ore and does not describe the product itself. The highest known liquid extractions are around 15%.
