Divergent responses of soil methane uptake to nitrogen addition across upland ecosystems

Key Points

• Soil methane uptake varies significantly with nitrogen addition across different upland ecosystems, suggesting diverse ecological responses.
• Increased nitrogen addition leads to varied methane uptake, with some ecosystems showing up to 50% changes in rates.
• The analysis of soil respiration and microbial activity sheds light on the mechanisms behind these divergent responses.
• Understanding these responses supports better land management practices to mitigate methane emissions.
