Healthy soil supports sustainable food production, enhanced biodiversity and cleaner air and water for present and future generations. Simply bury the underwear in the soil and check back 60 days later – if nothing is left but the elastic band, the soil is healthy. Soil Your Undies is a fun, hands on way to test soil biological health. However, tillage, excessive fertilizer and pesticide use, soil acidity, and other factors can destroy microbial communities, resulting in unhealthy soil. These microorganisms play a critical role in developing soil structure, making nutrients available for plant uptake, and decomposing plant residues. One teaspoon of healthy soil contains more microbes than there are people on the planet. By burying pairs of 100% cotton underwear in different kinds of soil and comparing decomposition rates, students can draw inferences about the rate of soil biological activity. Soil Your Undies is a campaign developed by the Innovative Farmers Association of Ontario and spread nationwide by the Soil Conservation Council of Canada. Soil your Undies meets Grade 3 and 7 learning outcomes but can be adapted for any grade level. Students learn the biology of different soils by burying 100% cotton underwear. Soil your Undies is an experiential test of microbial activity in soil. ![]()
