Soil your Undies

Healthy soil contains billions of microscopic organisms. Just one teaspoon of healthy soil contains more microbes than there are people on the planet! Soil microbes are constantly feeding on organic matter, like cotton underwear. 

The Soil Your Undies Challenge started in Oregon as a way to bring awareness to soil health. Simply bury a pair of cotton briefs for 60 days. When dug up, what’s left is an indicator of soil health, based on microbial activity in the soil that breaks down the cotton undies. Try it and become the first school in North Carolina to get on the map!
