Soil is the thin outer layer of the earth's crust in which plants can grow. It is literally the basis of all terrestrial ecosystems and through the great biogeochemical cycles it is connected to life anywhere else on the planet. At the same time, it is one of the least talked about spheres of Earth, mainly because we do not really see with the naked eye what goes on in it. It's all hidden in the microcosmos of the soil.
