Growth of mature boreal Norway spruce was not affected by elevated [CO 2 ] and/or air temperature unless nutrient availability was improved
The growth responses of mature Norway spruce (Picea abies (L.) Karst.) trees exposed to elevated [CO 2 ] (C E 670-700ppm) and long-term optimized nutrient availability or elevated air temperature (T E +3.9 C) were studied in situ in northern Sweden in two 3 year field experiments using 12 whole-tree...
