| Abstract/Contents: | "Leaf and root tissue of Lolium perenne L., Agrostis capillaris L. and Festuca ovina L. grown under ambient (350Ī¼1 1 Ā¹ COā) and elevated (700 Ī¼1 1 Ā¹) COā in a continuously Ā¹ā“C-labelled atmosphere and at two soil N levels, were incubated at 14Ā°C for 222 days. Decomposition of leaf and root tissue grown in the low N treatment was not affected by elevated [COā], whereas decomposition in the high N treatment was significantly reduced by 7% after 222 days. Despite the increased C/N ratio (g g Ā¹) of tissue cultivated at elevated [COā] when compared with the corresponding ambient tissue, there was no significant correlation between initial C/N ratio and Ā¹ā“C respired. This finding suggests that the COā-induced changes in decomposition rates do not occur via CO^D2-induced changes in C/N ratios of plant materials. We combined the decomposition data with data on Ā¹ā“C uptake and allocation for the same plants, and give evidence that elevated [COā] has the potential to increase soil C stores in grassland via increasing C uptake and shifting C allocation towards the roots, with an inherent slower decomposition rate than the leaves. An overall increase of 15% in Ā¹ā“C remaining after 222 days was estimated for the combined tissues, i.e., the whole plants; the leaves made a much smaller contribution to the C remaining (+6%) than the roots (+26%). This shows the importance of clarifying the contribution of roots and leaves with respect to the question whether grassland soils act as a sink or source for atmospheric COā." |
