The effects of increasing the availability of soil ammonium on the growth rate of nodulated M. truncatula was examined. Simulations were run allowing either the N2-fixation efficiency to vary while the rate of nodulation remained constant at 2% (blue) or allowing the rate of nodulation to vary while the N2-fixation efficiency remained constant at 150 µmol h−1 (g nodule dry weight)−1 (red). The dashed lines indicate the maximal rate of plant growth with exogenous ammonium (upper) and the maximal rate of plant growth when relying on N2-fixation (lower).
