Results clearly show that the cultivation stage is the hotspot for environmental impacts, caused
by field emissions, which represented 91% in the organic farming and 61% in the minimal tillage system.
The use of mineral fertilizers, in the case of the minimal tillage system, represented 34% of the emissions.
This research might help in the elaboration of rice production inventories, as well as in trying to provide
reliable information to stakeholders in order to choose sustainable products and processes.
