Summary

This 2025 study demonstrates that environmental DNA analysis is a more effective method than traditional hand sorting for evaluating earthworm biodiversity recovery in regenerative agricultural systems. The findings suggest eDNA offers enhanced sensitivity and efficiency for soil fauna monitoring, as suggested by the title's emphasis on eDNA superiority. The work contributes to improved protocols for assessing soil health indicators in farming system transitions.

UK applicability

These findings are directly applicable to UK regenerative and organic farming monitoring programmes, where earthworm communities serve as key soil health indicators. The methodology could inform UK soil health assessment standards and support monitoring requirements under environmental land management schemes.

Key measures

Earthworm species richness and abundance detected via eDNA versus hand-sorting; biodiversity recovery metrics under regenerative agriculture

Outcomes reported

The study compared environmental DNA (eDNA) analysis with hand sorting as methods for detecting earthworm species diversity and assessing biodiversity recovery under regenerative agricultural practices. The research evaluated the effectiveness and practicality of eDNA as a monitoring tool for soil fauna in farming system evaluations.
