Seven annual maps from 2015 to 2021 detail predicted application rates of nitrogen, phosphorus, and potassium fertilizers across England. The data provides estimates and uncertainty values at a 1 km x 1 km spatial resolution for each year and chemical type.
Use Cases
- Model nitrogen (N) application rates against land cover data to assess agricultural nutrient runoff
- Analyze temporal trends in phosphorus (P) and potassium (K) application from 2015 to 2021 at 1 km resolution
- Incorporate annual fertilizer uncertainty estimates into environmental risk assessments for water quality
- Compare predicted fertilizer application maps for N, P, and K to identify regional usage patterns
Strengths
- Seven consecutive years of annual data from 2015 to 2021 provides a temporal series
- Data is provided at a standardized 1 km x 1 km spatial resolution across England
- Includes separate predicted application maps and uncertainty estimates for three key fertilizer types (N, P, K)
Limitations
- Data is limited to England, not covering other UK nations or broader regions
- Relies on predicted application rates which may not reflect ground-truth measurements
- The 1 km resolution may be too coarse for field-level or hyper-local analysis
