Terrestrial nutrient cycling

Weathering, erosion and sediment transport

1 step

Chemical weathering dissolves silicates and carbonates, consuming Carbon dioxide

Photosynthesis and respiration (biosphere metabolism)

1 step

Respiration returns Carbon dioxide and releases energy

Soil food web energy transfer

1 step

Trophic cascades alter decomposer biomass

Progressive nitrogen limitation under rising CO2

1 step

Mineral nitrogen available to plants declines

Chemical weathering: CO2-driven dissolution and CO2 consumption

1 step

Soil CO2 (0.3-3 percent, 10-100 times air) dissolves to carbonic acid and lowers pH to 4.5-6

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

1 step

Root and microbial respiration lifts soil CO2 to 10-100 times air

Soil formation

1 step

Mineral surfaces accumulate and protect organic carbon as soil ages
