Show 11 more processes

Evaporation and transpiration

1 step

Roots draw soil water that leaves through leaf pores (transpiration)

Land water: infiltration, runoff and groundwater

1 step

Water soaks into soil, refilling soil moisture and aquifers

Soil food web energy transfer

1 step

Root energy channel (roots to herbivores)

Humification and SOM stabilization

1 step

Occlusion in aggregates

Mineral weathering and parent material

1 step

Carbonic acid forms from CO2 dissolved in soil water

Soil disturbance (fire, tillage, drought) and recovery

1 step

Aggregates and structure rebuild through roots, fungi and organic binding

Methane cycle: methanogenesis and methanotrophy

1 step

Methanotrophs oxidize Methane with methane monooxygenase in oxic layers and the rhizosphere, consuming roughly 20-80% of the methane produced (midpoint about 50% in paddies)

Infiltration and surface partitioning of rain (rain intensity vs 1-1000 mm/h soil capacity)

1 step

Macropores and root channels bypass the matrix and move water below 30-100 cm within minutes

Water movement

1 step

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

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

Soil state factors and the erosion-formation balance

1 step

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