Soil respiration

Soil respiration

Soil respiration normally refers to the total CO2 efflux at the soil surface.

It comprises a combination of processes:

* Biotic processes, which include respiration of the rhizosphere, microbes and fauna
* Chemical processes including oxidation of soil minerals, which can be pronounced at high temperature
* Physical processes, which include carbon dioxide degassing of the soil and transport of carbon dioxide to the soil's surface
