II SIGEE.  aFertilizers used as sources of nitrogen (N) are essential to increase the forage production (Costa et al., 2009), however, they lead to a higher N2O emission from soil (Gagnon et al., 2011). Nowadays, researches are establishing relationships between grass production and gas emission to figure out the better application N rates that harmonize productivity and less environmental impacts, i.e., more efficiency of N uptake by plants (Bell et al., 2016). Thus, the goal of this work was to establish the ratio between the amounts N2O emitted from soil to forage production in the Amazon of Mato Grosso.  aForage  aNitrous oxide  aÓxido nitroso1 aNASCIMENTO, A.
