English: Schematic representation of where soil carbon, nutrient, and water cycles, and soil biota underpin ecosystem services (adapted from Smith et al., 2014). Role in underpinning each ecosystem service shown by C, soil carbon; N, soil nutrients; W, soil water; and B, soil biota. Only soil carbon, nutrient, and water cycles, and soil biota are considered, so the figure does not represent a comprehensive overview of soil ecosystem services, which have been reviewed recently elsewhere.
