Recent and ongoing research has shown that the incorpora-
tion of air injectors in SDI systems can increase root zone aer-
ation and add value to grower investments in SDI.
Accordingly the aim of this study was firstly to evaluate the
technical feasibility of injection of ambient air into a subsur-
face drip irrigation tape, as a best management practice for
improving growth characteristics and crop production of corn
( Zea mays L.). Secondary to assess the effect of air injection
on soil penetration resistance and plant take off force.
