Supplementary file 1_Global meta-analysis reveals soil, climate, and management drivers of

A meta-analysis dataset from figshare, last updated April 15, 2026, synthesizing global field studies on enhanced-efficiency fertilizers. The data likely contains aggregated results on crop yield and nitrogen use efficiency responses to different fertilizer types under varying climate, soil, and management conditions. The dataset was created by author Xinping Zhang and is licensed under CC-BY-4.0.

Use Cases

• Modeling crop yield response to enhanced-efficiency fertilizers based on climate variables like mean annual temperature and precipitation.
• Predicting nitrogen use efficiency gains from fertilizer types like nitrification inhibitors or controlled-release urea based on soil properties.
• Analyzing the interaction effects of combined nitrification and urease inhibitors on crop performance across different management practices.
• Identifying optimal fertilizer strategies for specific crops like wheat, maize, and rice based on the meta-analysis results.

Strengths

• Quantifies specific average improvements: enhanced-efficiency fertilizers increased crop yield by 8.32% and nitrogen use efficiency by 25.90%.
• Reports effect magnitudes by fertilizer type, such as NI+UI improving NUE by 34.00% and CRU increasing NUE by 25.60%.
• Analyzes modulating factors including climate, soil organic carbon, total nitrogen, pH, crop type, and nitrogen application rate.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is a 232.4 KB DOCX file, indicating a small-scale, likely summary-level dataset rather than raw experimental data.
