Abstract | The objective of this study was to investigate the effect of elevated (550 ± 19 µmol mol−1) [CO2] on uptakeand utilization of nitrogen (N), phosphorus (P) and potassium (K) by soybean (Glycine max (L.) Merr) atthe 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] significantlydecreased the N concentration of the above-ground part at the beginning bloom (R1) stage, but had noeffect at the beginning pod (R3), beginning seed (R5) or harvest stage. The concentration of ureide inthe upper most fully-expanded leaf was not significantly affected by elevated [CO2] at any growth stage.Elevated [CO2] increased P concentration of the above-ground plant parts at the R1 and R5 stages, butdid not affect P concentration at the R3 stage or at harvest. However, K concentration of the above-ground plant parts and root was not affected by elevated [CO2] at any growth stage. At harvest, elevated [CO2] significantly increased N, P and K uptake in soybean seed. Results indicate that more N, P and Kfertilizers may be required to maintain the availability of these elements in the soil for soybean underfuture elevated [CO2] environments. |
