Soil Priming and Microbial Efficiency Data from Organic Acid Incubation Experiments

A dataset from figshare, last updated in April 2026, containing results from incubation experiments investigating microbial carbon use efficiency and soil organic matter priming. The data, authored by Hongxin Dong, measures priming effects ranging from -2 to 98 mg CO2-C kg-1 soil in agricultural soils with different nitrogen fertilization histories following organic acid inputs.

Use Cases

• Modeling the relationship between microbial carbon use efficiency (CUE) and soil organic matter priming based on experimental results.
• Analyzing the differential priming effects of acetic acid versus oxalic acid based on the described concentration ranges.
• Investigating the role of nitrogen availability in shaping microbial community composition (bacterial vs. fungal) and its impact on priming.
• Studying the loss of mineral-associated organic matter (MAOM) under low nitrogen conditions as indicated by the priming effect data.

Strengths

• Priming effect measurements are provided with specific concentration ranges (-2 to 98 mg CO2-C kg-1 soil).
• Data is structured in an XLSX file (215.8 KB), facilitating direct analysis.
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (215.8 KB), indicating limited scope.
