The objective of this investigation was to quantify the differences in soil carbon stores after exposure of birch seedlings (Betula pendula Roth.) over one growing season to ambient and elevated carbon dioxide concentrations. One-year-old seedling of birch were transplanted to pots containing ‘C4 soil’ derived from beneath a maize crop, and placed in ambient (350 μL L−1) and elevated (600 μL L−1) plots in a free-air carbon dioxide enrichment (FACE) experiment. After 186 days the plants and… CONTINUE READING
