A session devoted to molecular and isotopic techniques as used in soil organic matter research, including:
• Paleo-environmental and archaeological reconstructions,
• Organic matter dynamics (transformation, preservation, sequestration),
• Pedogenesis
All living species, be it animals, plants or microorganisms contain unique combinations of organic molecules and as such, each provide a unique input of organic matter into soils, both during life and after their demise. While a large proportion of such organic matter input in soils is rapidly degraded under normal circumstances, a significant proportion of more persistent organic molecules remain recognizable. The input of organic matter into soils is a prerequisite for soil formation and as such the dynamics of organic matter transformations in soils plays a crucial role in pedogenesis. In addition, it influences the fate of pollutants associated with the organic matter fraction, and determines to what extent a soil functions as a carbon sink or source. However, when the original organic molecules inputted in soils persist, they may serve as molecular proxies for historic organic matter input and serve as a tool in reconstructions of historic vegetation and/or archaeological reconstructions. At the same time the degradability of the organic molecules helps elucidate past and present soil conditions. All the research lines mentioned here have in common that they need a detailed examination of the original organic matter and its transformation products at a molecular level. This session aims to provide a platform for researchers, both fundamental and applied, working in any of the research lines focusing on molecular level examination of soil organic matter.
