Start: Fauna fragment, graze and condition litter
End: Fauna fragment, graze and condition litter
Fungi and bacteria colonise the fresh surfaces and soften the litter
and 1 more in this process

Temperature and moisture control microbial decay rate

4 steps

Aggregate formation and pore structure

3 steps

Biological weathering by roots, mycorrhizal fungi and microbes (plants speed weathering about 2-10 fold)

3 steps

Ocean carbon exchange and burial

2 steps

Living soil system

1 step

Aggregate formation and pore structure

Terrestrial ecosystem functioning

1 step

Decomposition

Roots and rhizosphere

1 step

Microbial loop releases nitrogen near roots

Saprotrophic fungi

1 step

Competition and antagonism among fungi and bacteria

Soil food web energy transfer

1 step

Bacterial energy channel (bacteria to bacterivores)

Organic matter decomposition

1 step

Fast phase: high-quality litter decays quickly

Nitrogen cycling

1 step

Coastal eutrophication and hypoxic dead zones

Mineral weathering and parent material

1 step

Organic acids and siderophores from roots and fungi chelate metals and dissolve minerals

Macroaggregate turnover and microaggregate formation

1 step

Microbes decompose the enclosed organic matter; their products coat it with clay

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

1 step

Grazers fragment litter and produce faecal pellets with high surface area that bacteria colonize

Rhizosphere phosphorus mobilization: phosphatases, organic acids and fast re-sorption

1 step

Low Phosphate induces plant and microbial phosphatases and phytases that hydrolyse organic P (about 30-65% of total soil P in many soils)

Nutrient limitation of net primary production

1 step

Free-living bacteria fix atmospheric nitrogen when molybdenum or phosphorus allow

Energy transfer through food webs

1 step

Energy channels in the soil food web

Trophic efficiency and top-down control

1 step

Detrital energy channel

Phosphorus decline and rescue across soil ages

1 step

Plants and microbes mobilise P with phosphatases and cluster roots

Hydraulic redistribution by roots (0.04-1.3 mm per day)

1 step

Redistributed water keeps topsoil roots, hyphae and microbes active in dry spells

Weathering

1 step

Biological weathering by roots, mycorrhizal fungi and microbes (plants speed weathering about 2-10 fold)
