From: Future nitrogen availability and its effect on carbon sequestration in Northern Eurasia
Temporal trends in annual N availability and annual net C sequestration in Northern Eurasia projected by TEM based on the RCP8.5 and RCP4.5 scenarios during the 21st century. a Trends in total N availability are partitioned by the contributions of net N mineralization, biological N fixation, atmospheric N deposition, and the application of N fertilizers for all ecosystems. b Same as a, but for all forests. The contribution of net N mineralization for ecosystems and forests underlain by permafrost in 2000 are also shown in a and b, respectively. c Trends in net C sequestration for all ecosystems. d Same as c, but for all forests. Net C sequestration in ecosystems and forests underlain by permafrost in 2000 are also shown in c and d, respectively
