Forest Soil Carbon Priming Responses to Nutrient Additions Across Lithologies

Subtropical Chinese forest soils from limestone and clastic rock parent materials were analyzed in a 42-day incubation experiment. The dataset includes measurements of the soil carbon priming effect under nitrogen, phosphorus, and combined NP additions, integrated with phospholipid fatty acid isotopic tracing and extracellular enzyme assays. Authored by Pengpeng Duan and last updated in May 2026.

Use Cases

• Model soil organic carbon vulnerability based on lithology and nutrient stoichiometry mentioned in the description.
• Analyze microbial community responses to nutrient additions using phospholipid fatty acid isotopic tracing data.
• Investigate relationships between priming effect and extracellular enzyme activity assays described.
• Test predictions of nutrient limitation regimes on carbon cycling across different parent materials.

Strengths

• Includes data from a controlled 42-day incubation experiment.
• Integrates multiple measurement types: priming, PLFA isotopic tracing, and enzyme assays.
• Compares two contrasting lithologies (limestone and clastic rock).
• Released under a CC-BY-4.0 license for open reuse.

Limitations

• Dataset is very small at 71.2 KB, indicating limited scope.
• Row count and column-level documentation are unknown, requiring inspection after download.
• Freshness should be verified as the last update is projected for 2026.
