Global Soil Nitrogen Cycling and Vegetation Greenness Dataset

A global dataset pairs soil nitrogen cycling rates and plant nitrogen uptake from 15N tracer studies with spatially equivalent NDVI data for unfertilized natural ecosystems. It examines how microbial nitrogen cycling regulates vegetation greenness across ecosystems worldwide. The dataset was created by Mohamed Abdel-Fattah and last updated in April 2026.

Use Cases

• Analyze the relationship between soil nitrogen retention rates and NDVI values across different biomes.
• Model the influence of autotrophic nitrification rates on vegetation greenness indices.
• Investigate correlations between plant nitrogen uptake data from tracer studies and ecosystem productivity metrics.
• Examine global spatial patterns of soil nitrate production pathways and their constraint on NDVI trends.

Strengths

• Global spatial coverage of natural ecosystems.
• Integrates two distinct data types: soil N cycling rates from 15N tracer studies and satellite-derived NDVI.
• Data is openly available under a CC-BY-4.0 license.

Limitations

• Dataset size is only 765.9 KB, indicating a limited scope or aggregated summary data.
• Specific row count and granularity of the underlying 15N studies are unknown.
• The temporal range for the compiled studies is not specified.
