- •
Elevated [CO2] just decreased the N concentration of the above-ground part at R1 stage.
- •
Elevated [CO2] increased P concentration in soybean at R1 and R5 stages.
- •
K concentration of the above-ground part was not affected by elevated [CO2].
- •
Elevated [CO2] significantly increased N, P and K uptake in soybean at harvest.
