Why did 1,000 Swiss citizens bury their underpants?
Summary
A group of 1,000 Swiss volunteers buried cotton underpants for two months to study soil health across Switzerland. Scientists analyzed how soil life breaks down the cotton to learn about soil quality and how it changes with land use.Key Facts
- The study used cotton underpants buried in soil to measure decomposition, a sign of biological activity in soil.
- Volunteers dug holes and buried two pairs of organic cotton underpants alongside teabags, which are also used to measure decomposition.
- After 30 and 60 days, participants dug up the underpants and teabags, recorded their state, and sent them for analysis.
- Decomposition rates show how active soil organisms are, which affects soil fertility and ecosystem health.
- The project involved 1,000 citizens, with 240 volunteers named as co-authors on the research paper.
- The research showed that how land is used has the biggest impact on soil health and biological activity.
- Healthy soil is important for farming, food security, and maintaining the environment.
- This citizen science project improved on previous methods by using underpants as an easier way to measure soil decomposition.
