N2O emission peaks observed in LVC pastures tended to be higher than those in AVC pastures in 5 out of the 7 sites (Fig. 1; Table 2). However, the delayed N2O peaks observed at Rio Grande do Sul (Brazil) were higher in the AVC (59 ± 11 mg N2O-N m−2 day−1) compared to the LVC (45 ± 18 mg N2O-N m−2 day−1) pasture. The level of N2O emissions observed at Balcarce and Manfredi (Argentina) and Taluma (Colombia) sites were lower than 50 mg N2O–N m−2 day−1.
