Global Meta-Analysis of Microbial Inoculants on Soil Phosphorus and Plant Performance

A meta-analysis of 308 studies with 3007 observations quantifies the effects of microbial inoculants on soil phosphorus availability and plant performance. The dataset, created by Hui Nie and last updated in April 2026, compiles global research on soil available phosphorus, phosphatase activity, and total phosphorus. It identifies environmental and management factors governing these responses.

Use Cases

• Modeling the relationship between microbial inoculants and soil available phosphorus based on the meta-analysis results.
• Analyzing the impact of environmental factors on phosphatase activity as described in the study.
• Training predictive models for plant performance using aggregated data on phosphorus turnover.
• Conducting secondary meta-analyses on soil phosphorus pools using the compiled 3007 observations.

Strengths

• Based on a substantial evidence base of 308 studies and 3007 observations.
• Includes multiple measured variables: soil available phosphorus, phosphatase activity, and total phosphorus.
• Data is openly shared under a CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic or methodological bias inherent to the aggregated studies.
