This study investigates how land use and Enhanced Rock Weathering (ERW) influence phosphorus (P) stabilization, availability, and coupled carbon-nitrogen-phosphorus (C-N-P) cycles. Particle-size fractionation, stoichiometric analysis, NanoSIMS, and basalt-based ERW are employed. Results show grassland soils have higher OM stocks and high OP-derived available P, whereas arable soils are dominated by inorganic P-complexes for P availability. Basalt addition increases soil pH, promotes OC stabilization, and enhances P availability, supporting climate-smart management in temperate soils.
