About the Database
Disclaimer – Alpha Release
This is a working version of the enhanced effiency fertilizer Emission Factor Database, released for feedback and review purposes only. While we have applied rigorous data collection, quality control, and validation procedures, errors or omissions may still exist.
The data included in this database has been extracted from publicly available, peer-reviewed scientific publications. We do not take responsibility for the accuracy, interpretation, or conclusions of the original studies, nor for how the data is used or interpreted by users of this platform.
If any data points appear relevant to your research, analysis, or decision-making, it is your responsibility to consult the original source material via the DOI or reference provided. This ensures the data is appropriate, complete, and correctly interpreted for your specific context or use case.
We strongly encourage users to provide feedback, corrections, or suggestions using the contact form or by emailing us at efdatabase@proba.earth. Your input is essential in helping us improve the reliability and value of this resource.
The Enhanced Effiency Fertilizer Emission Factor Database was developed to provide reliable, peer-reviewed emission factors for enhanced effiency fertilizers used in agricultural systems. This database supports more accurate greenhouse gas (GHG) inventories and research by compiling data from field experiments that specifically quantify the impact of stabilizers on N2O emissions from agricultural soils.
Data collection follows strict inclusion criteria, focusing on studies with clear experimental design, appropriate control treatments, and comprehensive metadata. Each study must provide sufficient information on location, crop type, fertilizer application rates, stabilizer type, and measured N2O emissions. The database extracts key variables including soil properties, climate conditions, and experimental parameters to ensure data quality and reproducibility.
Quality assurance involves rigorous cross-referencing, consistency validation, and expert review of all included studies. The resulting database serves researchers, policymakers, and agricultural practitioners seeking reliable emission factors for enhanced effiency fertilizer technologies. This standardized approach ensures that users can confidently apply these factors in their GHG accounting and environmental impact assessments.
