Abstract:
Global agricultural systems are increasingly moving towards organic farming to satisfy consumers’ increased
environmental awareness. Yet, shortage of fertilizers and more frequent water stresses are challenging agricul-
tural systems to minimize their environmental impact without compromising productivity and economic sus-
tainability. This study discusses how greenhouse organic tomato production behaves when multiple eco-
sustainable solutions are applied. In particular, organic tomato cultivation was supported by a specific bio-
stimulant treatment that included a microbial solution, based on Rhizobium, which was distributed onto faba
bean seeds; once a suitable fava bean biomass had been obtained, the plants were chopped and incorporated into
the soil in order to release nitrogen. In the trials considered, microbial solutions reduced organic tomato pro-
duction costs by 5 %. Considering that fertilization accounted for up to 7 % of total production costs, a large-scale
preparation of the microbial solution could trigger significant economic savings. The Life-Cycle Assessment
shows that organic tomatoes, with a lower yield, have a lower environmental impact than conventional pro-
duction only for 7 of the 15 evaluated impact categories. Combined agro-technical growing solutions are
economically viable in the presence of yields in organic compared to conventional, and their environmental
impact is attractive in both scenarios.
