From: Future nitrogen availability and its effect on carbon sequestration in Northern Eurasia
Characteristics of future C sequestration and N availability for Northern Eurasian ecosystems under the RCP8.5 and RCP4.5 scenarios. a Forest ecosystems include young forests (stand age <120-years-old) and old forests (stand age at least 120-years-old). b Non-forested ecosystems (combination of tundra, grasslands, shrublands, deserts, wetlands, croplands, and pastures). c All ecosystems. Positive values in the graphs represent cumulative C sequestration over the 21st century and negative values represent C losses. Circles represent the partitioning of N availability among net N mineralization, biological N fixation, atmospheric N deposition and N fertilizer application. Values within circles represent total N availability over the 21st century
