<b>Symbiosis type in nitrogen fixing trees determines greenhouse gas emissions: a global meta-analysis</b>

N-fixing trees is widely spread for planting forest and agroforestry ecosystems due to their advantages for improving soil quality and carbon sequestration. However, the impact of N-fixing trees on N₂O, CH₄, and CO₂fluxes relative to non-fixing trees remains uncertain. We use meta-analysis to discover this important knowledge gap. Specific description for this study and related dataset and code were attached.
