The 2020 Soil Your Undies challenge was a huge success, with over 200 pairs of undies being buried around Australia. In case you missed the excitement last year, the Soil Your Undies Challenge is a collaboration between Dr Oliver Knox, CottonInfo, UNE SMART Farms and UNE Discovery with the goal to increase awareness and understanding of soil health. To do this, participants of the challenge buried a pair of cotton undies for 8 weeks to see how much they broke down. Cotton is made of type of sugar called cellulose which the decomposers living in soil love to eat, so by analysing how much the undies broke down soil scientists like Oliver are able to see how healthy the soil is! Undies were excavated in December and sent back to UNE for analysis, but what exactly do we do with all these soiled undies?...
