Soil nitrogen turnover and N₂O emissions in permafrost landscapes of Northern China in a changing climate

The NIFROCLIM project is jointly funded by DFG and NSFC. The central goal of NIFROCLIM (soil nitrogen turnover and nitrous oxide emissions in permafrost landscapes of Northern China in a changing climate) is to gain a holistic, process-based and functional understanding of the gross nitrogen turnover as well as associated nitrous oxide (N2O) emissions for the main ecosystems present in the permafrost region of Northeast China by using an interdisciplinary approach involving biogeochemists, soil scientists, atmospheric physicists, biologists and molecular ecologists. Thus, NIFROCLIM aims at a strong contribution towards closing the large knowledge gaps on permafrost nitrogen biogeochemistry. Furthermore, NIFROCLIM is seen as a platform for international research on permafrost carbon and nitrogen biogeochemistry in China and beyond.




Ongoing work around Mohe

This summer, Prof. Bin Hu and a small team will return to the Mohe field site and choose another representative sampling area for a second set of samples. The aim is to test the influence of alders and their root nodules on the...[mehr]


Alder root nodules

We saw the importance of alders in fueling permafrost nitrogen cycling (Ramm et al. 2022) – but which bacteria exactly are there in the root nodules in the alder forest of Mohe? Alder (Alnus sp.) is commonly in symbiosis...[mehr]


Fire experiment on Disko Island

One of the most pressing research needs is the effect of arctic fires on the soil microbiome in permafrost soil as fires are increasing in the permafrost region due to climate change. Also concerning our study site in NE China, a...[mehr]


The second campaign in Mohe

Despite the Covid-19 pandemic, a field campaign at the Mohe permafrost site took place at the end of the growing season in 2020, supported by extraordinarily warm temperatures. Within the campaign, Prof. Liu was working on a...[mehr]
