Increasing levels of atmospheric CO 2  may change C and N dynamics in pasture ecosystems. The present study was conducted to examine the impact of four years of CO 2  enrichment on soil and root composition and soil N transformation in natural pastureland. Plots of open-top growth chambers were continuously injected with ambient CO 2  (350 µL L –1 ) and elevated CO 2  (625 µL L –1 ). Soil cores exposed to ambient and elevated CO 2  treatment were incubated and collected each year. Net N-mineralization rates in soil (NH 4 + -N plus NO 3 ˉ – -N), in addition to total C and N content (%) of soil and root tissues were measured. Results revealed that elevated CO 2  caused a significant reduction in soil NO 3  (P &lt; 0.05), however, no significant CO 2  effect was found on total soil C and N content (%). Roots of plants grown under elevated CO 2  treatment had higher C/N ratios. Changes in root C/N ratios were driven by changes in root N concentrations as total root N content (%) was significantly reduced by 30% (P &lt; 0.05). Overall, findings suggest that the effects of CO 2  enrichment was more noticeable on N content (%) than C content (%) of soil and roots; elevated CO 2  significantly affected soil N-mineralization and total N content (%) in roots, however, no substantial change was found in C inputs in CO 2 -enriched soil.
