Rot nodule biomass, and seedling biomass and growth were examined for 2-year-old Robiniapseudoacacia and Amorpha fruticosa seedlings following fertilization treatments. Organic fertilizer, solid com-bination fertilizer, and organic fertilizer plus solid combbiomass (g/plant) ranged from 3.00 to 7.06 for R. pseudoacacia and varied from 1.52 to 2.32 for A. fruticosa, respectively. In all treatments, root nodule biomass of R. pseudoacacia was significantly higher than those of A. fruticosa. Fertilization significantly increased root nodule biomass for only R. pseudoacacia, however, there were no significant differences in root nodule biomass among fertilization treatments. Root nodule biomass was not influenced by soil nitrogen (N) and phosphorous (P) concentrations following fertilization treatments. Seedling biomass (components and total) and growth (diameter at root collar and height) were strongly correlated with root nodule biomass for the two N fixing tree species.
