Short summary
The overall aim of this project was to investigate how the P cycling and speciation are affected by forest management, ash fertilization and climate change.
The specific objectives were as follows:
- To examine the speciation and solubility of P in representative Swedish forest soils, from the surface to 1 m depth.
- To investigate how the speciation and solubility of P in the O, E and upper B horizons are affected by whole-tree harvesting (WTH) and by ash fertilization.
- To elucidate the reactivity of the soil apatite in the mineral soil of Swedish forest soils.
- To produce scenarios on how P availability and leaching may change due to forest management and climate change.
The project constituted the core of a PhD thesis (Tuyishime, graduated in December 2022) and was part of a post-doc project (Adediran).
