- Association Productivity and nitrogen acquisition responses to elevated CO2 were positively related.
- Association Plant nitrogen acquisition decreased by 10% when productivity changed little.
- Intervention effect Plant nitrogen concentration was lower under elevated CO2.
- Association The productivity effect of elevated CO2 did not diminish over time.
- Association The nitrogen acquisition effect of elevated CO2 did not diminish over time.
- Association The elevated CO2 related decrease in plant nitrogen concentration diminished over time.
