The Soil Your Undies Challenge is back again in 2021 and bigger than ever! This year we want to send out 300 undies to be soiled all across Australia. Register your class now to be a part of this Australia wide citizen science project and test your soil health with us.

One pair of undies, 8 weeks in the ground, how much do you think will be left? Register now for your free challenge pack by clicking on the second link below! Registrations close July 23^rd unless we run out of undies first.
