## In brief

- Study published online in Nature Sustainability on 10 November 2026 (doi:10.1038/s41893-026-01992-8).
- Authors Bhaduri and colleagues argue that the choice of agricultural data source is a dominant control on uncertainty in nitrogen surplus estimates.
- Excess nitrogen from agricultural regions has environmental impacts, which is why the nature and drivers of nitrogen surplus matter.

## Why it matters

Nitrogen surplus estimates used in environmental assessments may differ substantially depending on which agricultural dataset is used, so readers should consider data source choice when interpreting such results.
