Psuedo ANOVA results showing percentage of explained variation attributed to the treatments for each traits. Shoot dry weight (SHOOT DW, g); root dry weight (ROOT DW, g); ratio of root to shoot dry weight (R:S); shoot % N (%N); vegetative NUE (NUE, %N/g DW); net N uptake to shoot (N UPT., gN); net N uptake to shoot relative to root dry weight (N UPT./R, gN.gDWroot⁻¹); ${\text{NO}}_3^{-}$ flux (NO3 FLUX, nm.gDW⁻¹.h⁻¹); ${\text{NH}}_4^{+}$ flux (NH4 FLUX, nm.gDW⁻¹.h⁻¹).
