Nitrogen-rich tropical/subtropical forest soil acts as a terrestrial source of nitrous oxide (N2O) emissions, a greenhouse gas commonly affected by soil nitrogen availability and soil moisture. However, in tropical and subtropical regions experiencing both elevated nitrogen deposition and altered precipitation regimes, it is unclear whether nitrogen deposition and precipitation regimes have interactive effects on forest soil N2O emissions and what roles N2O-associated nitrifiers/denitrifiers play in these interactions. We conducted a two-year field study in a subtropical evergreen broadleaf forest in southern China by applying four treatments: nitrogen addition (N), seasonal precipitation distribution change (P), both nitrogen addition and seasonal precipitation distribution change (NP) and a control (C). The Results showed that N2O efflux from the forest soil was significantly greater in the wet season than in the dry season, but was promoted by the NP treatment only in the dry season. Soil moisture and pH decreased in the P and N treatments, respectively. The abundances of the nitrifying gene AOA-amoA and denitrifying gene nosZ in the wet season and the abundance of the denitrifying gene nirK in the dry season differed significantly among the four treatments. A structural equation model showed that precipitation change was more important than nitrogen addition in affecting soil properties (e.g. moisture and pH) and N2O-associated nitrifiers/denitrifiers, while soil nirK- and nosZ-denitrifiers were the dominant functional microbes in regulating N2O emissions. The results support predictions of future nitrogen losses (N2O) in subtropical forests in the context of interactions between elevated nitrogen deposition and altered precipitation regimes.

“…6), coinciding with the trend of nitrification-derived N2O emissions. Indeed, high soil pH and low SOC content seem favorable for nitrificationderived N2O emission in fertilised upland soils, which contrasts to the higher N2O emission in soils with low pH and high SOC via conventional denitrification under high soil moisture conditions (Wang et al, 2017;Yin et al, 2023). These results highlighted the important roles of soil pH and SOC in regulating nitrification and denitrification related N2O emission through different mechanisms in agricultural soils.…”

“…Among these influential factors of N2O emission, soil pH has strong effects on the activities of nitrifiers and denitrifiers, and thus further affects N2O production (Wang et al, 2017;Zhu et al, 2019). For example, it is frequently observed that acid soils emit much higher N2O than alkaline soils, due to the inhibition of bacterial N2O-reductase enzyme and the activation of fungal denitrification under acidic conditions (Ji et al, 2022;Yin et al, 2023). In contrast, lower N2O emissions were observed in acid soils than alkaline soils using microcosm incubations, and this was attributed to the increase of nitrification and nitrifier denitrification rates with soil pH increase (Shi et al, 2017;Wrage-Mönnig et al, 2018;Tzanakakis et al, 2019).…”
