- Observation Oak control plots had the highest spring soil respiration, 2.96 μmol CO2 m−2 s−1.
- Observation Pine control plots had the highest spring soil respiration, 2.85 μmol CO2 m−2 s−1.
- Observation Oak control plots had the highest summer soil respiration, 2.92 μmol CO2 m−2 s−1.
- Observation Pine control plots had the highest summer soil respiration, 3.1 μmol CO2 m−2 s−1.
- Intervention effect Nitrogen significantly reduced soil respiration in oak plantations.
- Intervention effect Nitrogen significantly reduced soil respiration in pine plantations.
- Intervention effect Nitrogen reduced soil microbial biomass carbon in both plantations.
- Intervention effect Nitrogen significantly decreased soil microbial entropy in both plantations.
- Intervention effect Nitrogen significantly decreased the C/N ratio in both plantations.
- Mechanism Reduced microbial biomass carbon and fine root biomass may explain lower respiration.
- Association Nitrogen effects on soil carbon dynamics were more pronounced in oak than pine.
- Association Soil organic carbon accumulation increased with nitrogen inputs in oak.
- Intervention effect Pine soil organic carbon did not change significantly with nitrogen.
