Response of soil aggregate carbon and stability to simulated deposition of nitrogen and phosphorus in Pinus koraiensis forests

Key Points

• Soil aggregate carbon significantly increases with higher nitrogen and phosphorus deposition levels, indicating nutrient influence on carbon storage.
• Carbon stability in soil aggregates responds favorably, showing a marked improvement with nutrient addition, particularly in Pinus koraiensis ecosystems.
• Nutrient simulation involved applying varying levels of nitrogen and phosphorus to analyze effects on soil carbon metrics versus control conditions.
• The findings highlight the importance of nutrient management in forest soils, pointing towards improved carbon retention strategies.
