2,000 Underpants Reveal Soil Quality Secrets

Swiss researchers and citizen scientists have devised an original method to reveal the crucial, yet often hidden, processes occurring beneath our feet. By burying over 2,000 cotton underpants in the soil, they made the invisible world of soil quality tangible.

Soils are essential ecosystems, storing water and carbon, nourishing plants, and hosting a significant portion of the planet's biodiversity. Despite their importance, soils frequently receive little public attention. This neglect is concerning, as soil biodiversity is declining in many regions, with serious implications for agriculture, food security, and the overall stability of ecosystems.

The project aimed to bring soil health into public awareness, highlighting its critical role in supporting life on Earth. The buried underpants, acting as a visual indicator, demonstrated the dynamic biological activity within the soil, emphasizing its role in nutrient cycling and water retention.
