GoKawiilResearcher proposes building a device to map earthworm movements at paddock scale
A soil researcher writing on worm phenomics describes plans to develop a 'worm detector' capable of tracking the in-situ movements of individual and community earthworm populations across farmland. The author notes that while abundance and diversity of worms in agricultural ecosystems are well documented, almost nothing is known about how they move underground, and no existing method can capture such data. The post cites a 1988 Danish study by Mather and Christensen on Lumbricus terrestris as the closest prior attempt at tracking earthworm movement.
