Optimizing Water and Nitrogen Use Efficiency (WUE & NUE) with Airjection® Irrigation

Injection of air into the root zone environment has shown to enhanced crop productivity. Using a high efficiency venturi to inject air into water delivered through subsurface drip irrigation, commonly referred to as AirJection® Irrigation, has been shown to result in increased yields for a variety of crops.

In the current study, we assessed an economic analysis and techniques for assessing Airjection to optimize water and Nitrogen use efficiency in vegetable production. Overall, Airjection improved the economic returns for various crops favored the dominance of bacteria that enhance plant nitrate uptake with a potential reduction in nitrate leaching.
