When soils are flooded, they are lacking oxygen. Then, some microorganisms “breathe” iron, causing mineral transformations. This science communication film introduces a novel research approach for investigating iron mineral transformations in soils directly in the field, which has previously been possible only in the laboratory. It demonstrates the new method step-by-step and shows how the scientists apply it in the field. The viewer also learns about the relevance of iron mineral transformations for the environment. The research is part of an ERC-funded project (IRMIDYN) conducted by the Soil Chemistry Group at D-USYS, ETH Zurich, Switzerland.
