Cropland Soil Carbon Metrics from China, 2021

Key metrics from 55 cropland soil samples collected across a latitudinal gradient in China between March and June 2021. The dataset includes data on extracellular polymeric substance (EPS) production quantified through ¹⁸O-H₂O isotope tracing and ¹³C-labeled soil microcosm incubation experiments with four distinct organic substrates. It was authored by Yichao Wu and published under a CC-BY-4.0 license.

Use Cases

• Modeling soil carbon persistence based on microbial extracellular residue metrics.
• Analyzing the relationship between EPS production and different organic substrates.
• Studying latitudinal gradients in soil carbon composition across Chinese croplands.
• Calibrating isotope tracing methods for microbial activity in soil microcosms.

Strengths

• 55 samples provide a basis for statistical analysis.
• Includes data from controlled isotope tracing and microcosm incubation experiments.
• Covers a latitudinal gradient across China, offering geographic context.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The 90.0 KB size indicates a very limited scope of data.
