Soil Organic Carbon Fractions Under Crop Rotation and Monoculture, 0-90 cm Depth

An agricultural Luvisol soil profile from 0 to 90 cm depth was analyzed for soil organic carbon partitioning. The dataset contains measurements of fulvic acid and humic acid fractions, including their quantity, proportional contribution, and optical properties, under long-term crop rotation and monoculture systems. It was authored by Tianjing Ren and last updated on 2026-05-18.

Use Cases

• Modeling soil carbon persistence based on operational fractionation data mentioned in the description
• Comparing carbon allocation between dynamic and retained fractions under different cropping systems
• Analyzing depth-dependent responses of soil organic carbon fractions to agricultural management

Strengths

• Data covers a 0 to 90 cm soil profile, providing depth-dependent analysis.
• Focus on long-term agricultural systems allows for the study of management effects.
• Dataset is openly available under a CC-BY-4.0 license.

Limitations

• Dataset is small at 22.5 KB, indicating limited scope.
• Row count and column-level documentation are unknown, requiring inspection after download.
• The geographic location of the agricultural Luvisol is not specified.
