stores ~3000 Pg C, about four times the amount of carbon as is currently in
Earth’s atmosphere. As rising temperatures increase microbial activity, some of
this carbon is at risk of being respired to the atmosphere, creating a positive
feedback to climate change. To estimate the magnitude of this feedback we need
to understand how mechanisms controlling soil carbon decomposition change
throughout the soil profile and how these mechanisms respond to warming. Here I
present results from several experiments examining how mechanisms controlling
soil carbon decomposition change with depth. The understanding from these
experiments is then applied to one of the first experiments warming a whole
mineral soil profile <i>in situ</i>.</span><br></p>
