Microbial Carbon Use Efficiency in Subtropical Forest Soils on Limestone and Clastic Rock

Subtropical southwestern China soils were analyzed for microbial carbon use efficiency under nutrient additions. The dataset includes measurements of microbial growth rates, respiration, biomass turnover, CUE via 18O-H2O isotope labeling, phospholipid fatty acid profiles, and extracellular enzyme stoichiometry. The research was authored by Pengpeng Duan and last updated on 2026-05-12.

Use Cases

• Modeling soil carbon stabilization feedbacks based on lithology-controlled microbial CUE.
• Analyzing microbial community structure shifts based on phospholipid fatty acid profiles and enzyme stoichiometry.
• Investigating nutrient co-limitation patterns based on responses to C, N, and P factorial additions.
• Parameterizing carbon cycle models based on quantified microbial growth rates and respiration data.

Strengths

• Data originates from a full-factorial limiting factor assay with C, N, and P additions.
• Includes multiple measurement types: isotope labeling, enzyme stoichiometry, and phospholipid fatty acid profiles.
• Explicitly compares two contrasting parent materials: limestone and clastic rock.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small in scale at 41.3 KB, indicating limited scope.
