Listening to the Underground: Ecoacoustics and Soil Health

Ecoacoustics, a new field of science, uses sound to monitor soil health. Researchers have developed a technique to capture and analyze the sounds produced by soil-dwelling organisms, offering a non-invasive way to assess soil biodiversity. This could help improve soil health globally by providing valuable insights into ecosystem dynamics.

Adelaide, Aug 18 (The Conversation) -- A new frontier in soil health monitoring, ecoacoustics, is emerging. Astonishingly, 59% of Earth's species live in soil, playing crucial roles in maintaining ecosystem health. However, 75% of soils are damaged due to destructive practices, posing risks to biodiversity and food production.

Ecoacoustics studies the sounds produced by soil organisms, offering a non-destructive alternative to traditional monitoring methods. Researchers developed a technique using soundscapes, the amalgamation of distinctive underground sounds, to assess soil health. Healthy soils, rich in biodiversity, emit a lively array of crackles, clicks, and pops.

Initial trials, published in the Journal of Applied Ecology, show ecoacoustics effectively indicates soil health and restoration success. The promise of ecoacoustics lies in its potential to transform our understanding of soil biodiversity, aiding global conservation efforts.
