Soil chronosequences shed light on the silicon soil-plant cycle
As soils age, geochemical weathering becomes less important for supplying silicon to the biosphere while terrestrial vegetation plays a greater role. Félix de Tombeur and Jean-Thomas Cornelis of the University of Liege (Belgium) visited the University of Western Australia to study two rare dune soil chronosequences spanning 2 million years. The impoverished soils of these dunes support biodiverse ecosystems. Their […]
