Terrestrial ecosystem functioning

1 step

Decomposition

Aggregate formation and pore structure

1 step

Earthworm casts and burrows create stable aggregates and macropores

Roots and rhizosphere

1 step

Root channels and biopores left by dead roots

Terrestrial carbon uptake and release

1 step

Soil microbes decompose organic matter

Soil gas exchange and redox

1 step

Roots and microbes consume Oxygen and release CO2 in pores

Organic matter decomposition

1 step

Physical fragmentation by fauna, freeze-thaw and wetting-drying

Macroaggregate turnover and microaggregate formation

1 step

Macroaggregate breaks down and releases stable microaggregates

Bioturbation: fauna remodel soil structure

1 step

Net effect on structure depends on species, soil and management

Pedogenesis and soil horizon development

1 step

Organic matter accumulates at the surface forming the O and A horizons

Springtail and mite grazing of fungi: stimulation, defence and dispersal

1 step

Grazing mineralizes nitrogen held in fungal biomass; fauna as a whole contribute roughly a third of N mineralization in studied agroecosystems (estimate)

Energy channels in the soil food web

1 step

Fauna temporarily store carbon, then microbial necromass accumulates

Trophic efficiency and top-down control

1 step

Detrital energy channel

Nitrogen and phosphorus supply and limitation

1 step

Organic nitrogen is depolymerised to amino acids

Soil state factors and the erosion-formation balance

1 step

Topsoil (0-20 cm) concentrates organic carbon and roots

Organism-environment interactions

1 step

Ecosystem engineering and plant-soil feedback

Plant-soil feedback via litter quality

1 step

Nutrient-rich litter decomposes faster and releases more nitrogen
