Bury and wait
- Bury a pair of new cotton underwear, about 6 inches deep with the waistband showing above the surface. Wait for 60 days.
- Dig up the underwear and take a photo, upload to the Vidacycle app.
- The more degraded the pants are, the more biological activity there is likely to be in the soil.
