<span style="font-size: 9.5pt;" class="">Soil organic matter 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 class="">in situ</i>.</span><br class="">
