Adding oxidizing agents like H2O2 to your irrigation source to enhance the amount of dissolved oxygen is likely to be quite counter-productive. The problem with using oxidizing agents is they are highly intolerable by the beneficial soil-flora. Beneficial soil colonies behave as a 'lab in the soil' - apart from assisting in the bio-synthesis and selective uptake of minerals and nutrients, soil-microorganisms are the major supplier of dissolved oxygen in the growing medium. In fact the soil flora are one of the only organisms known to liberate oxygen by cleaving it from H2O directly at the root-zone - thus eliminating the soil colonies would be detrimental to your plants oxygen supply. The H2O2 will provide an immediate boost in dissolved oxygen following application, but even at negligible concentrations, with the damage sustained to the soil-flora you will quickly see a lull in dissolved oxygen content.
In aquariums, it is common practice to bubble air through the water to charge it with oxygen. This is not really an especially powerful way to add oxygen to water, but when coupled with the amount of dissolved oxygen contributed by water-borne microorganisms is sufficient for fish tanks that hold only a small amount of fish in many liters of water. In controlled experiments where sterile tanks are used to examine the controlled activity of aquatic pathogens, the water is nebulized through the air in a aerosol chamber upon circulation. In comparison to bubbling (<24% DO), passing the water through the air as a fine mist is a far more effective way to charge the water with dissolved oxygen, where by it becomes 'saturated' in dissolved oxygen (>36% DO). Their are many challenges to coordinate the supply of oxygen with nutrients in rooting mediums - this is the basis for NFT and aeroponic techniques.
