Soil Respiration Data from a 7-Year Precipitation Experiment in a Semi-Arid Grassland

A seven-year precipitation manipulation experiment (-70% to +50%) followed by a two-year recovery period quantified legacy effects on soil respiration and its components. The dataset, authored by Yanan Cui and published on figshare in 2026, likely contains measurements of soil respiration (Rs), autotrophic respiration (Ra), and heterotrophic respiration (Rh).

Use Cases

• Analyze asymmetric precipitation legacies on soil carbon fluxes based on the described drought and wetting treatments.
• Model the temporal dynamics of respiration components based on the described biphasic and convergent recovery patterns.
• Investigate shifts in dominant controls of respiration based on the described transition from microbial substrates to plant allocation.
• Compare sensitivities of plant- and microbially derived respiration based on the described contrasting Ra and Rh responses.

Strengths

• Based on a long-term, seven-year experimental manipulation.
• Includes a detailed two-year recovery period to assess legacy effects.
• Quantifies specific percentage changes in respiration components (e.g., +21.9% for Rs under wetting).

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 (79.0 KB), indicating limited scope.
