Global warming effects on soil carbon dynamics of forests
On 2. March 2016 by JoergSoil warming leads to increased microbial respiration, the depleation of soil C and a transfer of carbon from the soil to the atmosphere. To simulate responses of soil systems to Climate Change, we studies a long term soil warming experiment in the Austian alps.
At the long term soil warming site in Achenkirch in the Austrian alps, Andreas Schindlbacher, Wolfgang Wanek Werner Borken and I have examined adaptations of microbial physiology and soil respiration to warming and the effects of soil warming on organic matter chemistry.

In many forest soils, nitrogen deposition can slow decomposition, leading to increased carbon storage. Manganese limitation may be an important mechanism! Great paper by a colleague and friend, @EmilyDWhalen @NRESSPhD @unhresearchnews https://t.co/9fTxFKGsgK
Great work and really important for interpreting CUE measurements and the role of microbial physiology in C cycling in soil. #CUE #soil #soilC
