Bedrock Nitrogen Weathering Stimulates Biological Nitrogen Fixation [PDF]

The Bulletin of the Ecological Society of America, 2019
AbstractGlobal ecosystem models suggest that bedrock nitrogen (N) weathering contributes 10–20% of total N inputs to the natural terrestrial biosphere and >38% of ecosystem N supplies in temperate forests specifically. Yet, the role of rock N weathering in shaping ecological processes and biogeochemical fluxes is largely unknown.
