(b) soil horizon (“Horizonthauptsymbol”), (c) soil region (“Bodenregion”), and (d) pedo-climatic zone (“Bodenklimaraum”). Colours illustrate normalised values, which describe depth gradients. Sample numbers are characterized by dot size and numbers...
Photosynthesis is P, R is respiration, structure refers to leaf biomass, and the symbols are those of the energy language of Odum [10]: bullet symbol represents photosynthesis, hexagons are consumer compartments, tanks are storages, the circle represents external energy inputs, the heat sinks ...
