The ground beneath us is a complex, breathing biological system
In short: Far from being inert dirt, soil is a dynamic ecosystem. This documentary explores the hidden biological activity that shapes our world, from the surface down to the deep roots.
The film examines how soil forms through the continuous breakdown of organic matter, such as leaf litter and humus. It reveals the essential roles played by worms, bacteria, and fungi in creating a living system that stores vital nutrients and water. By looking at the interactions between deep roots and mycorrhizal fungi, the episode demonstrates how this hidden life makes plant growth possible.
