Title
Influence of Elevated Atmospheric CO2 Concentrations on Plant Nutrition
JP Conroy Australian Journal of Botany 1992. doi:10.1071/bt9920445
Other claims from this paper (7)
- Mechanism Elevated CO2 is expected to increase biomass production of C3 species through higher photosynthesis.
- Association The greatest productivity increase is expected at high soil nitrogen and phosphorus availability.
- Association Low nitrogen does not prevent a growth response to high CO2.
- Association Some C3 species fail to respond to high CO2 when phosphorus is low.
- Association CO2 enrichment reduces nitrogen requirement.
- Intervention effect Foliar, root and grain nitrogen concentrations are lower under elevated CO2 regardless of soil nitrogen availability.
- Recommendation Critical nutrient concentrations should be reassessed as atmospheric CO2 rises.
