How much do you think about the world beneath your feet? Soil is essential for life on earth and provides many ecosystem services, including carbon storage and providing habitats for billions of organisms. But one third of our global soils are already degraded and are at risk of further degradation from human activities, such as unsustainable farming practices, industrial activities, mining and other non-environmentally friendly practices. In 2002, the International Union of Soil Sciences (IUSS) marked the 5th December as World Soil Day, to celebrate the importance of soil as a critical component of the natural system and as a vital contributor to human well-being.

To mark this World Soil Day, I’m going to be highlighting my recent study, which used DNA metabarcoding as a method to investigate soil microbiomes for evaluating the success of forest restoration in Costa Rica.
