How Can You Tell If Soil Is Healthy? Just Listen to It.
Ground-breaking "ecoacoustics" use underground critter concerts to monitor a hidden ecosystem.
Scientists have, in recent years, started experimenting with using ecoacoustic tools to capture the full range of sounds in healthy ecosystems—such as in coral reefs, caves, and oyster beds —and applying those recordings to restoration efforts in damaged and degraded areas. Degradation causes significant biodiversity decline, hampering soil’s vital ecosystem services, such as water cycling, and results in colossal consequences for the world’s agricultural productivity, curbing crop yields and livelihoods.
