Abstract
The objective of this study was to investigate the effect of elevated (550±19μmolmol−1) [CO2] on uptake and utilization of nitrogen (N), phosphorus (P) and potassium (K) by soybean (Glycine max (L.) Merr) at the free-air carbon dioxide enrichment (FACE) experimental facility in northern China. The above-ground biomass and root biomass were significantly increased under elevated [CO2]. Elevated [CO2] significantly decreased the N concentration of the above-ground part at the beginning bloom (R1) stage, but had no effect at the beginning pod (R3), beginning seed (R5) or harvest stage. The concentration of ureide in the upper most fully-expanded leaf was not significantly affected by elevated [..
