More than 1,000 volunteers in Switzerland buried cotton underwear to measure soil biological activity, with gardens showing the fastest decomposition and lawns the least.

The experiment highlights how land management practices significantly influence underground ecosystems, showcasing the varying levels of microbial activity across different types of terrain.

This study underscores the importance of understanding soil health for sustainable agriculture and ecological balance, revealing that garden soils are more biologically active compared to those in lawns.
