The Quantifying the effects of interacting nutrient cycles on terrestrial biosphere dynamics and their climate feedbacks (QUINCY)
project is an ERC grant of Sönke Zaehle
and aims at clarifying the role of the interacting terrestrial nitrogen and phosphorus cycles and their effects on terrestrial C allocation and residence times as well as terrestrial water fluxes. We contribute to soil model development and have set up a greenhouse ecotrone experiment where we are now studying the effects of elevated CO2
on belowground carbon allocation, soil carbon and nitrogen mineralization, microbial activity and soil carbon storage.
