Figure 1From: Contributions of nitrogen deposition and forest regrowth to terrestrial carbon uptakeChanges in land carbon uptake in response to increasing nitrogen deposition and both nitrogen deposition and forest regrowth. The presented values are differences in net carbon uptake modelled with and without increasing atmospheric nitrogen deposition for mature, young and middle-aged forests. The bars show global carbon uptake averaged for 1980's and 1990's.Back to article page
