“…The leaf litter in late harvest treatment represents a significant carbon input (Amougou, Bertrand, Cadoux, & Recous, ; Amougou, Bertrand, Machet, & Recous, ) and creates a mulch layer, which increases soil moisture by reducing soil evaporation. Such conditions are known to be favorable to N 2 O emissions by denitrification as recently reported with Miscanthus (Peyrard, Ferchaud, Mary, Gréhan, & Léonard, ). However, we did not find significant differences in PDA between harvesting dates.…”

“…However, as discussed previously, the favorable conditions of moisture and temperature associated with the fast decomposition that was observed in our study could explain the response observed. Overall, our study showed that 70% of the N O emitted over 1 year with fertilized sugarcane could be attributed to the presence of crop residues, which confirms recent studies that emphasize the importance of postharvest periods for high N 2 O emissions and the role of crop residue management (e.g., Peyrard et al 2017;Rezaei Rashti et al 2017;Tongwane et al 2016). This findingisparticularlyrelevantinsituationswithperennialor semi-perennial crops and no-tilled arable systems in which crop residues are left at the soil surface, thereby promoting favorable conditions for emissions at the soil-straw interface (Peyrard et al 2017;Shan and Yan 2013;Vasconcelos et al 2018).…”

“…However, the C available from the straw also contributes to ad e c r e a s ei ns o i lO 2 availability resulting from increases in microbial activity, which can be linked to the correlation observed between N 2 O and CO 2 emissions in PCA analyses. Oxygen depletion and CO 2 emissions due to microbial activity during straw decomposition (Badagliacca et al 2017;Peyrard et al 2017) combined with a WFPS of approximately 60% after rain events might have favored N 2 Oproductionby denitrification with the appearance of anoxic spots, mainly at the soil-straw interface. In summary, our findings indicated that mulching provided favorable soil conditions for both nitrification and denitrification processes, which could occur simultaneously.…”
