Private gardens, cultivable lands, permanent grass areas, and lawns were each given a uniform object in 2021: white organic cotton underwear, buried eight centimeters below the surface with the waistband exposed. After two months, briefs from private gardens lost approximately 58% of their material, while those from lawns lost 40%, arable fields 51%, and permanent grassland 47%. Research conducted by Agroscope and the University of Zurich, released on 26 August 2026 in *Plants, People, Planet*, concluded that land use was the most significant factor influencing fabric breakdown. The study comprised 1,100 packs with 780 viable site returns; degradation was assessed by area, which was considered more accurate due to soil particles adhering to the fabric. The findings reveal that soil fertility has a profound impact on decomposition, indicating that undergarments could serve as an uncomplicated indicator of soil health.<\/p>\n
Among the primary land uses, private gardens displayed the highest rates of decomposition, attributed to elevated concentrations of soil nutrients and organic carbon. Lawns, although maintaining stable conditions, exhibited the least degradation, potentially a result of limited plant diversity and management practices. Decomposition diminished at greater altitudes and peaked where compost was applied. Over-application of phosphorus fertilizers in gardens raises environmental issues. Soil organic carbon on its own was not a major predictor of decomposition, highlighting nutrient availability as more critical than carbon presence. The study employed the Tea Bag Index as a benchmark, revealing analogous trends and reinforcing the notion of underpants as a sensitive indicator of soil fertility.<\/p>\n
Private gardens showed excessive phosphorus levels, indicating problems associated with over-fertilization. The research proposes the “underpants index” as a useful tool for evaluating soil fertility but urges additional studies to uncover the factors driving decomposition. Despite certain limitations, the study illustrated a clear relationship between land use and decomposition, advocating for this approach as a viable preliminary evaluation of soil health.<\/p>\n","protected":false},"excerpt":{"rendered":"
