Abstract: An iron fulvate solution production method capable of producing an iron fulvate solution efficiently within a short period of time is provided. The method comprises: preparing a processing apparatus which comprises: a hermetic container internally having a closeable processing space; a steam jetting device operable to jet high-temperature and high-pressure steam into the hermetic container; a supply section for supplying a raw material into the hermetic container; and a discharge section for discharging, to the outside, a processed liquid produced through processing of the raw material by the steam; inputting a raw material from the supply section into the processing space of the hermetic container of the processing apparatus, wherein the raw material comprises a woody plant material (and/or a herbaceous plant material) and an iron material, as main sub-raw materials; subjecting the raw material to a subcritical water reaction processing, under stirring, while introducing steam having a temperature of 120 to 250° C. and a pressure of 5 to 35 atm for a woody plant material, or steam having a temperature of 100 to 200° C. and a pressure of 2 to 25 atm for a herbaceous plant material, into the processing space in which the raw material is input, to obtain a mixed solution containing iron fulvate; and separating the iron fulvate from the obtained mixed solution to take out an iron fulvate solution.
