Abstract
Method and apparatus for sub-surface injection of irrigation water infused with treatment gas such as air or oxygen. The infusion of gas into the water is by the use of a cavitating mixer-injector, and the resulting infused water under pressure is conveyed under pressure to the roots of a crop, where it is discharged in the root zone beneath the surface of the soil. The released effluent is water containing dissolved gas at atmospheric pressure, gas released from the water when the pressure was released, and gas in the micro-bubbles.
