Nitrophilous Plant
Definition
A plant species that grows preferentially on nitrogen-rich soils. Examples include stinging nettle (Urtica dioica), broad-leaved dock (Rumex obtusifolius), and elder (Sambucus nigra). Their presence in an otherwise nitrogen-poor sward can signal localised organic enrichment.

- Stinging nettle, broad-leaved dock, elder
- Preference
- Nitrogen-rich soils
- Forensic relevance
- Clandestine grave detection via localised enrichment
Common questions
Why does a clandestine grave attract nitrophilous plants?+
Decomposition releases substantial nitrogen into the surrounding soil, and species favouring nitrogen-rich conditions colonise or grow more vigorously in that enriched patch, creating a visible or spectral anomaly against the surrounding vegetation.
Does a nitrophilous plant patch alone confirm a burial site?+
No, nitrogen enrichment can also result from manure, fertiliser or septic leakage, so a nitrophilous plant patch is an investigative lead requiring ground-truthing, not standalone proof of a grave.
