Phosphorus-33 Uptake by Seven Grassland Plant Species

Environmental Information Data Centre data measures phosphorus-33 uptake by seven herbaceous plant species from three injected sources: orthophosphate, DNA, and calcium phosphate. The dataset contains plant biomass, radioactivity from scintillation counting, and the calculated proportion of supplied 33P taken up into shoots after six days.

Use Cases

• Compare 33P uptake proportions from orthophosphate, DNA, and calcium phosphate sources across the seven plant species.
• Analyze the relationship between plant biomass and measured radioactivity from scintillation counting data.
• Model species-specific nutrient uptake efficiency using calculated proportion of supplied 33P taken up into shoots.

Strengths

• Data covers seven common and co-occurring herbaceous plant species for comparative analysis.
• Includes measurements from three distinct phosphorus sources: orthophosphate, DNA, and calcium phosphate.
• Contains derived metrics like the calculated proportion of supplied 33P taken up into plant shoots.

Limitations

• Sample size and number of experimental replicates are unknown, limiting statistical power assessment.
• Data is from a single, controlled pot experiment, which may not fully represent field conditions.
• Temporal coverage is limited to a single harvest six days after 33P injection.
