GoKawiilSwiss study buries 2,000 cotton underpants to map national soil health
Agroscope researchers enlisted about 1,000 citizen scientists to bury more than 2,000 pairs of organic cotton underwear and 12,000 tea bags at 1,000 sites across Switzerland. After one and two months, participants dug up the items and returned them so scientists could measure how much material had been eaten away by soil organisms, using decomposition as a proxy for biological activity. Private gardens showed the highest soil activity of any land type tested, while lawns showed the lowest.
GoKawiil's interpretation of the reporting above, not reported fact.
Soil degradation is a global threat to food production, water quality and biodiversity, yet most people have no easy way to gauge the health of the ground beneath them. This low-cost, citizen-run method shows that a simple garment can generate usable scientific data at national scale, potentially opening soil monitoring to non-experts and policymakers alike. Findings tying decomposition to nutrient and organic matter levels also give land managers a rough diagnostic tool for spotting struggling soils.
- Private gardens had the most biologically active soil; lawns had the least among land types studied.
- Underwear decomposition correlated strongly with soil nutrient and organic matter levels.
- The buried-underwear method offers a cheap, accessible way for anyone to get a first read on local soil activity.
Luster Leaf Rapitest Soil Test Kit — If the buried-underwear experiment made you curious about what's happening under your own garden, this classic at-home kit lets you check pH plus nitrogen, phosphorus and potassium without waiting two months for cotton to rot. It's a great companion to the study's finding that nutrient and organic matter levels drive soil biological activity — and an easy way to see why private gardens outperform lawns.
