Micropedology to understand Technosol functioning: technogenic substrate structures on thin sections
Abstract
Micropedology contributes to provide a better understanding of soil processes. Technosol micromorphology may so improve the knowledge about the evolution and future management of such soils (Adderley et al., 2010). Large sources of technogenic substrates and diversity of soil processes justify the importance to identify anthropogenic microstructures and to specify their formation and evolution in terms of mineral weathering, organic matter degradation or aggregate formation. Such qualitative information may also be correlated to porosity quantification by images analysis of thin sections (Jangorzo et al., 2013). Here, we studied two contrasted Technosols: (1) a 10- year constructed one for which we characterized the parent materials (paper mill sludge, green waste compost and thermally treated material) and the micromorphology at several different times after the set up of the soil (Séré et al. 2010) and (2) a 60-year Technosol developing on iron industry deposits where a forest has established (Huot et al., 2014) for which thin sections of the different layers were morphologically characterized and some analysed by SEM-EDS. Regarding the specificity of the Technosol constituents (e.g. hydrophobicity, coarse texture), the preparation of soil thin sections has been adapted. Such various anthropogenic features as paper-mill sludge, thermally treated material, droplets or laminar structures of iron industry deposits were identified as specific microstructures. Biological activity was underlined by evidences of the progressive degradation of the organic matter brought by the constructed Technosol’s parent materials, but also by new associations formed with organic constituents coming from the spontaneous colonising plants. Organo-mineral associations were also described showing the aggregation genesis due to the impact of pedological factors. Micropedology has to be developed in the study of Technosol pedogenesis. It can so be considered as a relevant tool to study the evolution of man-made soils, as it is well-adapted to consider the diversity of the Technosol constituents, their large heterogeneous spatial localization and the specific intensity of soil processes.
