Table 1_Differential responses of mineral-associated organic carbon and particulate organi

A field study dataset comparing concentrations of mineral-associated organic carbon (MAOC) and particulate organic carbon (POC) in desertifying grasslands of Inner Mongolia, China. The data includes mean MAOC values of 15.66 g/kg and 14.99 g/kg at two depths in the typical steppe, and 12.10 g/kg and 11.64 g/kg in the desert steppe, alongside POC concentrations. Authored by Hao Peng and published on figshare in May 2026.

Use Cases

• Modeling soil carbon stock changes based on MAOC and POC fractions
• Analyzing the relationship between soil carbon fractions and iron/aluminum oxide concentrations
• Studying the vertical distribution of soil carbon components under desertification pressure
• Investigating links between microbial community composition and mineral-associated carbon stabilization

Strengths

• Provides specific mean concentration values for MAOC and POC at two soil depths (0–10 cm and 10–20 cm) in two distinct steppe ecosystems.
• Explicitly investigates underlying drivers including Fe/Al oxides, exchangeable calcium, and microbial community composition.
• Published under a permissive CC-BY-4.0 license, allowing for reuse and redistribution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• The dataset is very small (26.3 KB), suggesting limited scope or a summary of findings rather than raw observational data.
