In recent decades, novel techniques of synchrotron-based X-ray spectroscopy and spectromicroscopy have emerged as powerful methods to study the biogeochemistry of nutrient as well as toxic elements in environmental samples, such as soils and sediments. The evaluation of element-specific or species-specific X-ray fluorescence or absorption patterns [X-ray Fluorescence Spectroscopy, XRF; X-ray Absorption Near-Edge Spectroscopy, XANES] enables environmental scientists to reveal patterns of element distribution and element speciation in environmental samples (e.g. soils) at different scales (from the m- or km-scale in landscapes or watersheds down to the micron- or submicron-scale in soil aggregates. Even spatial correlations between elements and/or element species can be addressed by analyzing the same sample at different element specific X-ray energies. The application potential of synchrotron-based spectroscopy and spectromicroscopy in soil science will be demonstrated by several examples. Furthermore, technical limitations as well as future prospects of the application of XAFS and (mu)-XAFS techniques for the analysis of soils and important biogeochemical interfaces in soils will be addressed.
