Chemical weathering: CO2-driven dissolution and CO2 consumption

8 steps

Humification and SOM stabilization

3 steps

Weathering

2 steps

Phosphorus decline and rescue across soil ages

2 steps

Weathering, erosion and sediment transport

1 step

Show 6 more processes

Nutrient availability and leaching

1 step

Nutrient pools: mineral, organic matter, exchangeable, and soil solution

Mineral weathering and parent material

1 step

Which weathering reaction dominates

Viral shunt: phage lysis recycles bacterial carbon and nitrogen

1 step

Surviving microbes take up the lysate and mineralize part of it; the rest sorbs to minerals or becomes necromass (the viral shunt)

Litter quality, climate and fauna control decay

1 step

Microbial residues stabilise on minerals as soil organic matter

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

1 step

Ectomycorrhizal hyphae bore tunnels 3-10 micrometres wide into feldspar and hornblende

Soil state factors and the erosion-formation balance

1 step

Subsoil below 40 cm holds old, mineral-bound carbon
