Oxygation

Optimising delivery and benefits of aerated irrigation water

Oxygation involves mixing atmospheric air with irrigation water using a venturi and delivering it via a surface or subsurface drip irrigation system.

Increasing competition on supply of fresh water for irrigation by agricultural, domestic, sports and industrial users demands water use efficient irrigation methods and compliance with environmental regulations.

Final Reports

The diverse nature of NPSI investments is shown in two final reports which have just been completed. One concerns research into use of oxygation as a technique on various Queensland crops, while the other has an extension focus for WA vegetable growers.

Oxygation

Final report

Oxygation involves mixing atmospheric air with irrigation water using a venturi and delivering it via a surface or subsurface drip irrigation (SDI) system. 

Oxygation as a tool delivers air into the crop root zone. Oxygen limitations can be significant in compacted, saline, and water logged soil, and with high BOD effluent irrigation water.

Investigations into Oxygation

Oxygation of fig and pineapple crops was the interest of Central Queensland University student Michael Law, whose project built on investigations into the technique as a means of generating healthier interactions between water, soil and plant physiology.
