A Multi-site Field Dataset of Ammonia Volatilization and Associated Soil and Environmental

High-frequency chamber-based measurements of daily ammonia fluxes from fertilized upland soils across multiple sites, years, and fertilizer treatments. The dataset integrates derived cumulative emissions and emission factors with detailed soil properties, environmental conditions, and crop management data. Seong Min Moon published this structured framework on figshare to support the development of country-specific emission factors.

Use Cases

• Estimating country-specific ammonia emission factors based on cumulative emissions data.
• Analyzing the relationship between ammonia volatilization and controlling factors like soil moisture and air temperature.
• Evaluating process-based agroecosystem models using a standardized reference dataset.
• Linking nitrogen management practices to ammonia emissions and crop yield information.

Strengths

• Measurements were conducted using a standardized static acid-trap chamber system consistently across three field sites.
• Dataset integrates high-frequency daily NH3 flux measurements with detailed ancillary data on soil, environment, and management.
• Intensive sampling following fertilizer application allowed accurate capture of short-term emission dynamics.
• Analytical reliability was confirmed through calibration procedures, blank corrections, and consistent laboratory protocols.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data reflects geographic bias inherent to its collection in South Korean cabbage cultivation.
