There’s a hidden world beneath your feet, the world of earthworms, springtails, fungi, and bacteria. We hardly ever see these little creatures, but their impacts are huge.


Episode 1: Living Soil – a Habitat Hidden from View

Soils and their inhabitants play a big role for the overground world, from food security to climate change. It’s a special habitat, full of surprises. In this episode, host Anja Krieger learns more from co-producer Matthias Rillig and soil scientist Johannes Lehmann. Published on World Soil Day, December 5, 2020.


Episode 2: Fungi – the Kingdom of Mushrooms, Spores, and Networks

Hundreds of millions of years ago, plants started to colonize the land. But amazingly, they did this without roots. So how on Earth did these early plants feed themselves? It looks like they found some helpful friends: The so-called mycorrhizal fungi. How does the plant-fungi relationship work? Is it love or just a deal? And how do fungi travel? In this episode, Anja learns more from Katie Field, Toby Kiers, Bala Chaudhary and podcast co-producer Matthias Rillig. Published December 18, 2020.


Episode 3: The Soil Food Web – A Jungle in Tiny Dimensions

In this episode, Anja and Matthias go on an underground safari through the hidden jungle of the soil. We hear from Diana Wall about a tiny worm that is so tough it survives in Antarctica. Richard Bardgett introduces us to collembola, also known as springtails. Stefan Scheu and Maddy Thakur reveal which animals are considered the “wolves of the soil”, and Kate Scow delves into bacterial communities. How do all these organisms work together as a system?

Episode 4: Methods – How to Explore a Microscopic World 

If you dig out a handful of soil, what do you see? Really, not that much? That’s one reason the study of soil is such a challenge. It’s a lot of stuff mushed together, crumbs, roots, dead stuff, critters. How do you map that complex landscape and ecosystem? In this episode, scientists share their methods and challenges, and dream of new technology to improve the understanding of soil in major ways – if it just existed! Meet Asmeret Asefaw Berhe, Kate Scow, Marcel van der Heijden and Maddy Thakur. Publication: February 19, 2021.
