Fujimin® is the high concentrate fulvic acid solution which can be obtained by only the mass production technology using timber from forest thinning. Fulvic acid is one of the components of humic substances generally obtained from humic soil in forest. While fulvic acid has the effect of facilitating the absorption of fertilizer by plants and improving the soil environment, it can normally be found only in trace amounts in the terrestrial soil and the bottom of water bodies.
