Sounding Soil – Listening to the soil

By

Biovision is one of those listening carefully as it is using the installation “Sounding Soil” to raise the public’s awareness of the importance of our soils.

Sounding Soil is an inter and trans-disciplinary research project to increase our understanding of soil ecosystems. To date more than 20 soil areas in Switzerland have been recorded, including intensively and extensively used agriculture land, Alpine meadows and woodland soils. The sound recordings include the animals that live in the soil, such as springtails

Climate change and the world’s growing population is further increasing the importance of food security. Healthy soils are crucial as they underpin food security and biodiversity. This was why special recording and measurement techniques were developed for the Sounding Soil project in order to provide a quick and simple way to measure and analyse soil activity and biodiversity in future.

“In contrast to air pollution or clean (drinking) water, people have little understanding of the soil on or in which their food is grown,” says Sabine Lerch, Project Manager at Biovision Foundation for Ecological Development. In fact, the amount of healthy soil in Switzerland has dramatically declined in recent decades. Intensive cultivation, the use of mineral fertilisers and chemical pesticides together with developments that seal off soils are all reducing soil fertility. The initial results from Sounding Soil demonstrate a difference between extensively and intensively cultivated soils. Whereas recordings from organic soils with their countless living organisms produce a diverse soundscape, there is a silence from a field of conventional sugar beet or industrial-scale potatoes. 

Sounding Soil is a cooperation between the Zurich University of the Arts (ZHdK), the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL), the Swiss Soil Monitoring Network (NABO) at Agroscope, ETH Zurich and the Biovision Foundation.

Healthy soil is life!

Soil is the fundament for life on Earth, provides food and feed for all creatures above and below ground and plays a major role in climate protection! Soils bind atmospheric CO2, absorb rain water while prevent flooding, store water in long dry seasons, and buffer the extreme adverse impacts of the fast changing climate.

Soil – The voice of biodiversity

The research of Marcus Maeder, main initiator of the Biovision project Sounding Soil, shows scientifically for the first time: the biodiversity and intensity of underground life can be measured acoustically.

It creaks and hums, slurps and scratches

Our soil is alive! This was the experience of around 200 participants in Biovision’s Citizen Science Sounding Soil project last year. The evaluation of the recordings resulted in some surprising findings.

“Sounding Soil sparked my curiosity!”

Regula Gutierrez, a piano teacher at Kantonsschule Uster in Zurich, and her partner Branko Previti, a retired organic farmer, tried Biovision’s Sounding Soil project – and for the first time in their lives, they heard the sound of the soil in their garden.
