The new publication in the journal Geoderma, authored by Laurel ThomasArrigo and Ruben Kretzschmar, explores iron geochemistry in Icelandic peat soils.

In soils, transformations between iron mineral phases are dependent on soil conditions. A new research article, published today in the journal Environmental Science: Processes and Impacts, follows the transformation of ferrihydrite in flooded rice paddy soils. The article authored by Andrew Grigg, Laurel ThomasArrigo, Katrin Schulz, Katherine Rothwell, Ralf Kaegi (EAWAG) and Ruben Kretzschmar, is part of the ERC IRMIDYN project.

Why do some product phases form preferentially to others during iron mineral transformation in soil? A new paper, published in Environmnetal Science & Technology by Luiza Notini (ETH Soil Chemistry), Laurel ThomasArrigo (ETH Soil Chemistry), Ralf Kaegi (EAWAG) and Ruben Kretzschmar (ETH Soil Chemistry), demonstrates that products of Fe(II)-catalysed transformation of ferrihydrite depend on the pre-existing mineralogy of the system.

Congratulations to Xu Fang, who yesterday defended his doctoral thesis.

Members of the ERC IRMIDYN team have returned to field sites along the Elbe estuary, northern Germany, to conduct a new round of field experiments.

The annual Soil Chemistry hiking excursion was a two-day event this year, hiking from St Jakob in Uri to Engelberg, and staying at the Bannalpsee.

We are very pleased to welcome Pierre Lefebvre to the Soil Chemistry team as a new postdoctoral researcher.

Worachart Wisawapipat, Associate Professor of Soil Chemistry and Biogeochemistry at Kasetsart University in Thailand, is joining the Soil Chemistry group for six months during his Sabbatical.

A new publication, co-authored by Danielle Rushworth (former guest of the ETH Soil Chemistry group), Iso Christl (ETH Soil Chemistry), Kevin Hoffmann (ETH Soil Chemistry alumnus), Ruben Kretzschmar (ETH Soil Chemistry) and colleagues from the Univeristy of Vienna, Univeristy of Wageningen and University of Basel, has recently been released online. The work, published in the journal Geomicrobiology, explores the mobilisation of Cu from Cu sulfide by methanobactin.

Laurel ThomasArrigo and Ruben Kretzschmar are co-authors of a new study that simulates the iron mineral cycling that might have occured in ancient oceans. The article has been published in Geochimica et Cosmochimica Acta and is available online now.
