only marginally significantP = 0.0574
The local response in nodule number tended to differ between functional groups: nodulation in legume soil was lower than in soil conditioned by non-legumes, but this effect was only marginally significant and probably due to the strong response to V. cracca soil inoculum (interaction between functional group and compartment, F 1,54 = 3.77, P = 0.0574).
