Macadamia Seedling Growth and Rhizosphere Data from Controlled P and AMF Experiment

A controlled pot experiment by Ya Ning, last updated in April 2026, assessed the impact of phosphorus supply and arbuscular mycorrhizal fungi inoculation on Macadamia integrifolia seedlings. The dataset includes measurements of seedling growth, biomass allocation, organ-level phosphorus concentrations, rhizosphere soil properties, and fungal community composition. It was published under a CC-BY-4.0 license on figshare.

Use Cases

• Modeling the non-linear relationship between phosphorus supply and seedling biomass based on the three P levels tested.
• Analyzing the functional differentiation between specific AMF inoculants (Glomus mosseae vs. indigenous consortium) based on their effects on plant growth and nutrient uptake.
• Investigating the association between AMF colonization and total plant biomass, as described in the results.
• Studying shifts in rhizosphere fungal community composition and α-diversity in response to phosphorus and AMF treatments.

Strengths

• Data is derived from a controlled experiment with three phosphorus levels and two distinct AMF treatments.
• Specific quantitative results are reported, such as a 42.9% increase in aboveground biomass and an 18.4% increase in root P concentration under certain conditions.
• Published under a permissive CC-BY-4.0 license, facilitating reuse.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (12.5 KB), indicating limited scope.
