Soil Mineral-Associated Organic Matter Composition Under Crop Diversity

Data from a 2-year agricultural field experiment examining the effect of a crop diversity gradient on mineral-associated organic matter (MAOM) composition and its susceptibility to phosphorus-induced desorption. The dataset was created by Cynthia Kallenbach and last updated on 2026-04 25. It includes measurements from soils under wheat monoculture, wheat-bean intercrop, and systems with perennial cover crops.

Use Cases

• Modeling the relationship between crop diversity and soil organic matter composition based on pyrolysis-GC/MS characterization.
• Analyzing the susceptibility of mineral-associated organic matter to nutrient-induced desorption based on short-term incubation data.
• Investigating early indicators of soil response to agricultural diversification based on molecular composition shifts.

Strengths

• Data originates from a controlled field experiment with a defined crop diversity gradient.
• Includes molecular composition characterization via pyrolysis-GC/MS and desorption incubation results.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single 2-year trial; temporal and geographic scope is limited.
