Topsoil electroconductivity doubled after the field trial and simulation results predicted significant soil salt accumulation by factor of 2. Maize production with long-term wastewater irrigation at various salinities was modeled, and no significant yield losses were observed after 50 years of simulated irrigation. Both harvests produced yields and qualities comparable to commercial farm standards, and no significant differences were found between water types. Silage maize and sweet corn ( Zea mays L.) were grown over the summer of 2012–2013 under the following flood irrigation treatments: wastewater and freshwater with and without fertilizer.

The field experiment was established at the Shepparton Wastewater Treatment Plant in Shepparton, Victoria, to compare effects of wastewater irrigation to conventional irrigation. Effects of wastewater irrigation on crop production and soil health were investigated in two ways: a field experiment addressing short-term effects and modeling longer-term impacts. While wastewater can potentially offer a nutrient advantage over conventional irrigation, crop yield increases may be offset by effects of high salinity. In Australia, interest in wastewater reuse has grown.
