More specifically, the invention relates to the novel agricultural application of dissociated vanadium ions possessing redox potential, and to related methods. The method according to the invention is suitable for increasing the yield and biomass of plants, the essence of which lies in applying vanadium to the plant growth medium, to the plant, or to both, in order to enhance the nitrogen-fixing capability of microorganisms capable of fixing atmospheric nitrogen.
