Phosphorus Content in Chinese Plant Organs Across 18 Ecoregions

Phosphorus content measurements for plant organs across Chinese forests, grasslands, and deserts. Data includes organ-specific means and biomass-weighted totals derived from field investigations conducted between 2013 and 2019. The dataset was created by Cong Yu to support calculations of vegetation phosphorus density.

Use Cases

• Model vegetation phosphorus density (g m–2) using organ-specific phosphorus content and biomass-weighted totals.
• Compare phosphorus allocation patterns between leaf, twig, trunk, and root organs across 18 ecoregions.
• Analyze spatial variation in plant phosphorus content across forest, grassland, and desert ecosystems in China.
• Investigate relationships between ecosystem type and organ-specific nutrient concentrations using mean values.

Strengths

• Covers 18 distinct ecoregions across China.
• Provides data for four specific plant organs: leaf, twig, trunk, root.
• Includes both organ-specific means and biomass-weighted calculation methods.
• Data collected over a 7-year field investigation period (2013-2019).

Limitations

• Dataset is very small at 30.3 KB, indicating limited sample size or summary-level data.
• Unknown row count suggests aggregated summary statistics rather than raw observational records.
• Geographic scope is limited to China, not globally representative.
