Hongze Ma in OpenAIREApplying biochar to soil has been advocated as an effective measure to improve soil fertility and increase carbon (C) sequestration. Biochar is often co-applied with nitrogen (N) fertilizers in agricultural ecosystems, however, the interactive effects of biochar and N addition (BN) on soil greenhouse gases (GHGs) fluxes, soil C and N fractions, and yield has not been investigated. Here, we manipulated a global meta-analysis to explore the effects of biochar and N addition and their interaction on the GHGs, soil C and N fractions, and yield by assembling 75 articles. Results indicate that across all studies, biochar, N, and BN additions all increased soil CO2 emissions (8.5%–29.6%), yield (4.2%–58.2%), soil organic C (SOC, 1.8%–50.4%), dissolved organic C (DOC, 2.7%–30.0%), and total N (TN, 6.8%–15.6%), but had no significant effect on CH4 fluxes. Biochar addition reduced N2O emissions (−21.3%), global warming potential (GWP, −19.8%), greenhouse gas intensity (GHGI, −28.2%), NH4+ (−17.8%) and NO3− (−10.7%), whereas N addition increased these indexes. The interaction effects of BN on CO2 and N2O emissions, GWP, TN, and NH4+ contents were antagonistic, while CH4 emissions, DOC, MBC, NO3−, and yield exhibited synergistic responses. Notably, soil GHGs responses varied depending on geo-climatic factors, edaphic properties, biochar and N treatment parameters, and experimental scenarios. These findings indicate that the co-addition of biochar and N has the potential to mitigate climate change and improve yield, providing a valuable reference for the improvement of climate-smart agriculture.

Global warming and nitrogen (N) deposition have a profound impact on greenhouse gas (GHG) fluxes and consequently, they also affect climate change. However, the global combined effects of warming and N addition on GHG fluxes remain to be fully understood. To address this knowledge gap, a global meta-analysis of 197 datasets was performed to assess the response of GHG fluxes to warming and N addition and their interactions under various climate and experimental conditions. The results indicate that warming significantly increased CO2 emissions, while N addition and the combined warming and N addition treatments had no impact on CO2 emissions. Moreover, both warming and N addition and their interactions exhibited positive effects on N2O emissions. Under the combined warming and N addition treatments, warming was observed to exert a positive main effect on CO2 emissions, while N addition had a positive main effect on N2O emissions. The interactive effects of warming and N addition exhibited antagonistic effects on CO2, N2O, and CH4 emissions, with CH4 uptake dominated by additive effects. Furthermore, we identified biome and climate factors as the two treatments. These findings indicate that both warming and N addition substantially impact soil GHG fluxes and highlight the urgent need to investigate the influence of the combination of warming and N addition on terrestrial carbon and N cycling under ongoing global change.
