We used an ad-hoc designed biodiversity experiment, with sown meadow plant communities forming independent combina- tions of FD and PD (low/low, low/high, high/low, high/high values, plus monocultures) and used ion- exchange membranes to monitor changes in soil N (i.e. NH4+-N and NO3−-N) availability through time (four sampling times per year, i.e. seasonality). Results Our results showed a positive diversity effect for soil NH4+-N, with mixture communities yielding higher levels of NH4+-N than the corre- sponding monocultures. Within mixtures, commu- nities with combinations of both high FD and PD showed the highest NH4+-N availability. Most impor- tantly, although seasonality strongly affected soil N availability, diversity effects were generally consist- ent through time in the case of NH4+-N. In addition to these diversity effects, communities with higher pro- portion of nitrogen-fixing species also showed higher soil N availability.
