It is well known that all biological processes are regulated to some extent by environmental processes. The role of temperature, water and the supply of energy in the form of readily available substrates all have key roles in regulating soil organic matter transformations. However, these factors frequently interact and the soil microbial community which drives the processes may adapt to the conditions. This makes predicting the effects of environmental changes of soil organic carbon stocks particular difficult. Research in this area is addressing these themes.
