<b>Land-use-specific hydrological regimes modulate divergent soil carbon stabilization pat

Subtropical red soils from two over-35-year field experiments comparing paddy and upland systems under four fertilization regimes. The dataset quantifies soil organic carbon fractions and plant- and microbial-derived carbon using biomarkers. It was authored by Juan Yang and last updated on 2026-05-08.

Use Cases

• Modeling divergent soil carbon stabilization pathways based on land-use-specific hydrological regimes.
• Analyzing the impact of long-term manure fertilization on particulate vs. mineral-associated organic carbon.
• Investigating the relationship between enzyme activity and carbon partitioning under different fertilization regimes.
• Comparing plant-derived vs. microbial-derived carbon contributions to soil organic carbon in anaerobic versus aerobic systems.

Strengths

• Data originates from two over-35-year field experiments, providing long-term observational context.
• Quantifies specific carbon fractions (POC, MAOC) and sources using biomarkers (lignin phenols, amino sugars).
• Compares four distinct fertilization regimes (CK, N, NPK, NPKM) across two land-use systems.

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 (24.3 KB), indicating a limited scope of observations.
