ABSTRACT:
This invention provides methods of enhancing plant growth or yield, comprising exposing soil to hydrogen gas (H2), and growing plants in the soil. The H2gas employed can be generated by electrolysis of water, produced by H2evolving microorganisms, and/or produced by legumes. In accordance with the invention, soil can be exposed to H2and plants then grown in it, or H2can be applied directly to soil in which plants are already growing. In one embodiment, the invention comprises obtaining an aqueous extract from H2-treated soil, and applying the extract to soil, seeds, and or plant roots.
