Calling all farmers, students and gardeners alike! The Murraylands and Riverland Landscape Board invite you to bury your find out just how active hyour soil biology is.

Biology within the soil is responsible for consuming all kinds of organic materials and breaking them down as a part of the nutrient cycle. This simple experiment asks you to bury your undies to provide a tasty meal for soil biology; the quicker the undies are consumed the more active your soil biology is.

Burying your undies is an easy way to compare the biological activity in different soil types, at numerous locations on the farm, in various crop types, in garden beds, under a variety of watering regimes or even in different environments. Just remember to let us know where you have them buried when you send back the soiled undies.
