Living Soil – a Habitat Hidden from View

Soil is full of amazing life with its own intrinsic value. Just like many other species, we humans benefit from it: Healthy soil not only provides food, feed, fiber and fuel, it also contributes to the stability of the whole Earth system. But living soils are at risk all around the world. So, in this episode, podcaster Anja Krieger and soil ecologist Matthias Rillig take a look into the sustainable future: How can we, as individuals and societies, nurture and restore the ecosystems of the soil?

The list of how humans are causing trouble in the soil is pretty mind-blowing, kind of overwhelming. It’s connected to all that is central to our modern human societies - industrial agriculture, synthetic chemistry, city sprawl, global mobility and so on and on. In this episode, Matthias Rillig, Anja Krieger and their guests Maddy Thakur and Asmeret Asefaw Berhe explore the human impacts on soil and their cascading effects.

If you dig out a handful of soil, or a whole bucket full, what do you see? Really, not that much? Well, yes, 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. Soil is a very complex, intensely 3D-structured environment. How do you map that landscape? In order to look at the fine structures of a root, scientists have to painstakingly lay them bare. If they want to catch a critter, they have to lure it into a trap. And with very tiny organisms, it’s sometimes just impossible to get that sample. In this episode, scientists share their challenges and methods, and dream of new technologies to improve our understanding of soil in major ways - if it just existed!

In this episode, Anja and Matthias take you on an underground safari through the hidden jungle of the soil. And they’ve won some excellent scientists as tour guides. You’ll hear from Diana Wall about a tiny worm that is so tough it even lives in Antarctica or hot deserts. Richard Bardgett introduces you to collembola, also known as springtails - tiny insect-like animals that can jump like crazy! 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, and why does this soil food web matter greatly to us as well?

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: A group of fungi provided them with nutrients from the ground, fossils suggest. Today, the vast majority of plants team up with these so-called mycorrhizal fungi, which live in their roots. In return for nutrients, the plant provides the fungi with carbon in the form of sugar and fats. It’s an age-old symbiosis, and one that continues to fascinate soil scientists. How does the plant-fungi relationship work? Is it love or just a deal? In this episode, Anja learns more from Katie Field, Toby Kiers, Bala Chaudhary and podcast co-producer Matthias Rillig, and explores the world of fungi: How do they travel the world, and what would the world look like from a fungal perspective?

There’s a crazy place beneath your feet, a jungle of sand, silt, and clay, of solids and pores. Some of the most diverse and overlooked communities on Earth live here, in a world unlike anything we know - completely dark, of tiny proportions, and full of surprises. Even the air and water aren’t the same. Soils and their inhabitants play a huge role for the overground world, from food security to climate change. What do scientists know about them, and how are they exploring soils? In this first episode of the Life in the Soil podcast, host Anja Krieger learns more about the soil habitat from soil scientists Matthias Rillig and Johannes Lehmann.

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. In fact, the world just wouldn't be the same without them. Soil stores more carbon than the atmosphere and all plants together, filters water, is pivotal for biodiversity and at the center of agriculture and food security. Welcome to Life in the Soil, a podcast series by the plant, fungal and soil ecology lab at Freie Universität Berlin, supported by the BiodivERsA research network. Tune in to our series to hear more from some of the world’s best soil scientists. We'll launch World Soil Day, December 5, 2020.
