Healthy soil may be easier to detect by sound than by sight

Ever thought about listening to the soil under your feet? New research reveals that the sounds of soil-dwelling critters can indicate the health of the land, offering a new way to monitor and restore ecosystems.

Ayurella Horn-Muller reports for Grist.

In short:

Ecoacoustics, the study of environmental sounds, can be used to monitor soil health by detecting the presence and diversity of underground organisms.
Researchers found that soils with richer soundscapes, indicating more biodiversity, are healthier and less degraded.
Scientists are exploring whether playing recordings of healthy soil sounds can aid in the restoration of degraded lands.

Key quote:

“You can actually use sound to listen to the soil, and get an indication of soil health, based on the little critters moving around.”

— Jake Robinson, microbial ecologist at Flinders University

Why this matters:

This method is groundbreaking, not just for the science community but for anyone concerned about the environment. Healthy soils are the bedrock of agriculture, climate stability, and even human health. Read more: Growing veggies in the city this year? You may want to check your soil.
