A researcher discusses the need for developing worm detectors to map earthworm movements in agricultural paddocks, noting that while their abundance and diversity are well-studied, little is known about their individual and collective movements. The only prior in-situ studies mapping worm movements were conducted by Mather and Christensen in 1988 and 1994, and the author explores potential technologies like ground-penetrating radar or microwaves to advance worm phenomics research.
