Phosphorus (P) stands out as a central element for the functioning of terrestrial ecosystems, with its speciation being a key factor for bioavailability. This work aimed to develop, optimize, and apply novel synchrotron-based X-ray (micro)spectroscopy methods for soil P analysis at the macro- and micro-scale. A novel approach for the speciation of P using XANES spectroscopy was developed. The shifts in soil C, N, P and S speciation in mountain forest soils across a temperature gradient were revealed. At the microscale, P speciation modulates tree´s root functional traits.
