Summary

In our study we investigated the effect of soil phosphorus (P) status on legume occurrence and on phytodiversity of organically managed permanent grassland sites. Therefore, we realized screenings on 2 m x 2 m plots with a clear spatial
differentiation between the functional groups ‘legumes’ and ‘non-legumes’ on five mown pasture sites under organic management in north-eastern Germany. We found no significant difference between the phosphorus content of aboveground biomass of legumes and the associated non-legume group. However, we detected a significant difference between the soil PDL contents of these two groups with lower contents in
soils of the legume patches whereas the different P fractions and thus different P availability on the mineral site could not explain the occurrence of legumes. Contrary
to reports by many ecologists, we could not confirm a clear relationship between soil phosphorus and species number.
