Field Experiment Data on Nutrient Effects on Brown Patch Disease in Tall Fescue

Elizabeth Tracy Green's field experiment investigates how nutrient addition amplifies plant disease epidemics. The dataset includes results from an old field experiment on tall fescue (Lolium arundinaceum) and a re-analysis of a previous experiment, totaling 624.7 KB of R, CSV, and text files. Data was last updated on June 1, 2026.

Use Cases

• Modeling direct and indirect nutrient effects on disease based on field experiment results
• Analyzing pathogen species interactions, such as between brown patch and anthracnose
• Applying structural equation models to integrate individual- and population-level ecological hypotheses

Strengths

• Data from a controlled field experiment testing specific ecological hypotheses
• Includes a re-analysis of a previous experiment for framework expansion
• Files are provided in multiple formats (R, CSV, TXT) for reproducibility

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Description metadata is limited; actual data quality requires manual inspection after download
