Other claims from this paper (5)
- Intervention effect Elevated CO2 gave positive responses of tobacco biomass and nitrogen use efficiency.
- Observation A large amount of fertilizer-derived 15N was partitioned to tobacco stems at the expense of leaves.
- Intervention effect The non-fertilized root had an N concentration equal to that of the partially fertilized root.
- Intervention effect PRN increased root exudates of sugar and organic acid compared with CRN.
- Intervention effect Increased root biomass from nutrient patchiness did not enhance plant total N uptake.
