Overview

• Studies show that healthy soils emit complex soundscapes, indicative of diverse invertebrate communities.
• Acoustic monitoring has proven as effective as traditional methods for assessing soil health, but is less invasive and costly.
• The research highlights the critical state of global soils, with 75% currently degraded.
• Eco-acoustics could democratize soil health monitoring, making it accessible for wider use in conservation and farming.
• Future applications may include using sound frequencies to enhance soil health and promote beneficial microbial growth.
