In the world above ground, there's plants, insects, mammals and birds, but most importantly, a lot of people. Below us, there's a whole underground world of moles, larvae, worms, fungi, bacteria, woodlice, spiders, centipedes and much more.  Most soil animals are small, but they do great things for nature. In Onder het maaiveld - junior editie, a group of children discover the spectacular world on the other side of the soil, step by step.
