Figure 1.1 depicts the soil system and its connections to the other terrestrial spheres. It serves to illustrate the various concepts about the soil system that have appeared since Hans Jenny first suggested that soil could be usefully conceived in that manner. Jenny’s earliest ideas seem to have been first set down in 1930 when he approached soils from a general theory of state, in which “soil properties, soil processes, and soil‐forming factors are united into a comprehensive system” (Jenny, 1930, 1053). Later, in his classic book Factors of Soil Formation (1941), he treated soil as a physical system to underline its status as a natural body. He also recognized that the soil system is an open system to which substances may be added or removed, a point taken up by later pedologists.
