In Switzerland, farmers and garden owners are burying 2,000 pairs of underwear in various parts of the country, as part of a soil quality study.
The Agrosco Research Institute will send a pair of cotton underwear to volunteer participants for burial on farmland.
These clothes will be examined at a later time to determine how they have been degraded by microorganisms in the soil.
"This is an indicator of soil quality," said the project manager, Marcel Van Geer Hegden.
The environmentalist, in an interview with the German News Agency, referred to similar experiences that were carried out using underwear in Canada, but not on this scale.
The pants will be buried in the soil, then a pair of them will be photographed in lawns and ponds after a month, and a second pair after a second month. Later, how the natural fibers degraded will be digitally analyzed, and the more holes, the healthier the soil.
