Residual Soil Nitrogen Estimates for Canadian Agricultural Lands

Agriculture and Agri-Food Canada provides the Agri-Environmental Indicator Residual Soil Nitrogen (RSN) dataset. It estimates the annual amount of nitrogen remaining in soil after harvest on Canadian agricultural lands. The dataset was last updated on 2026-04 09.

Use Cases

• Modeling nitrogen leaching and environmental impact based on post-harvest soil estimates.
• Assessing agricultural sustainability and nutrient management practices based on annual residual nitrogen.
• Analyzing regional trends in soil nutrient balance across Canadian agricultural lands.

Strengths

• Data is provided by the authoritative national agency Agriculture and Agri-Food Canada.
• Offers multiple file formats including FGDB/GDB, GEOJSON, and CSV for flexibility.
• Annual estimates provide a time-series perspective on soil nitrogen.

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 bias inherent to its focus on Canadian agricultural lands.
