Effectiveness of tested fertilizers was assessed through a yield analysis, and proved that digestate may represent a viable alternative to urea (6.97 and 6.48 t -1 ha ). Nevertheless, considering CO2 emissions from digestate and the numerous passes in field needed for its spreading, the use of this fertilizer in extreme dry conditions requires specific considerations.

Il recente sviluppo del fenomeno dei cambiamenti climatici ha negativa- mente influenzato numerosi settori produttivi tra i quali quello agricolo. Per assicu- rare una produzione alimentare soddisfacente a livello globale, l’agricoltura ha dovuto incrementare il ricorso ad input esterni di sintesi con notevoli risvolti negativi a livello ambientale, come l’aumento delle emissioni di gas serra. In questo studio sono state monitorate le emissioni di CO2 e CH4 dal suolo in una coltivazione di mais da insila- to con differenti strategie di concimazione: (i) frazione liquida del digestato da reflui suini, (ii) urea e (iii)
