Embracing the dynamic nature of soil structure: A paradigm illuminating the role of life in critical zones of the Anthropocene
Soils form the skin of the Earth’s surface, regulating water and biogeochemical cycles and
generating production of food, timber, and textiles around the world. Changes in soil and its …
