We soiled our undies for science!
The Soil Your Undies Challenge is a simple way to test soil biology/microbial activity.
Just bury a pair of 100% cotton underwear for 60 days and then dig it up to see how much has decomposed. If just the elastic remains you have healthy soil!
You can also bury 2 pairs in different spots and compare the results.
How does it work?
McLean County Ag in the Classroom sponsored a friendly competition among local FFA Chapters for the #SoilYourUndiesMcLeanCounty Challenge. Ag students buried 2 pairs of undies in 2 locations on their school grounds & then dug them up 60 days later.
Thanks to Olympia, Heyworth, Tri-Valley & Lexington FFA Chapters for participating! Check out the results of our experiments in the photos below.
