Figure 1

Cumulative shoot biomass production (a, b), N (c, d) and P uptake (e, f) by wheat (a, c, e) and faba bean plants (b, d, f).
Each symbol represents a single harvest and is the mean of three replicates. Curves are derived from Eqn 1 using mean parameter estimates. NM-SW, uninoculated sole wheat; NM-MW, uninoculated wheat mixed with faba bean; Fm-SW, inoculated sole wheat; Fm-MW, inoculated wheat mixed with faba bean. Similar symbols are also used for faba bean plants.
