Global Fine Root Nutrient Concentrations Across 372 Species Combinations

372 unique combinations of species, root diameter, depth, and soil are compiled from 56 published studies. This dataset measures the concentration and translocation dynamics of 14 nutrients in fine roots (less than 5mm diameter). The data primarily originates from experiments on temperate and coniferous trees but includes diverse biomes and vegetation types.

Use Cases

• Analyzing nutrient concentration patterns (e.g., nitrogen, phosphorus) across different root diameters.
• Comparing nutrient retranslocation properties between grass, shrub, and tree functional types.
• Examining how nutrient dynamics vary with rooting depth and soil conditions across temperate, tropical, boreal, and tundra systems.
• Modeling the role of fine roots as a source and sink for nutrients in ecosystem biogeochemistry.

Strengths

• Compiles data from 56 distinct published studies, providing a synthesized view of the field.
• Covers 14 different nutrients, allowing for multi-element analysis of root chemistry.
• Includes 372 combinations of species, diameter, depth, and soil, enabling detailed cross-factor comparisons.
• Spans diverse biomes and vegetation functional types, increasing generalizability.

Limitations

• Column names and the exact row count are not provided by any source, limiting structural clarity.
• Conflicting 'last updated' dates (1997 and 2026) create uncertainty about data currency and maintenance.
• The specific license is noted as 'other-license-specified', requiring users to investigate terms.
