Forest Floor: Carbon cycling in forest floors https://www.wsl.ch/de/projekte/carbon-cycling-in-forest-floors/
The project quantifies carbon fluxes in forest floors along gradients in climate and bedrock in Switzerland and Germany. The approach is to measure radiocarbon contents in C pools and fluxes, and tracing isotopically labelled (13C, 15N, 2H) litter in the forest floor and in the mineral soil beneath.
