Who knew soiling your undies could be so much fun? …April 15 kicks off National Soil Conservation Week and the Soil Conservation Council of Canada wants you to bury a pair of cotton undergarments to check the health of the soil under your care. …The Soil Your Undies test shows just how biologically active your soil is. After a couple months buried, there shouldn’t be much left of your knickers if there is abundant life in your soil. To get started, all you need is a pair of new, 100 per cent cotton white briefs, a shovel, and a flag to mark the site. A helpful step-by-step guide on how to properly Soil Your Undies is available at www.soilcc.ca.
