      abstract     = {Increasing plant species richness decreases soil NO3-
                      concentrations in experimental plant mixtures, but the role
                      of particular plant functional groups has remained unclear.
                      Most analyses have focused on particular times of the year
                      or were restricted to NO3-. We tested whether plant species
                      richness or particular plant functional groups affect the
                      size of plant-available N pools in soil (KCl-extractable
                      N03, dissolved inorganic N and organic N [DON] and total
                      dissolved N [TDN] in soil solution) and N concentrations and
                      pools in aboveground biomass. Furthermore, we assessed
                      seasonal variations in the effects of plant species richness
                      and plant functional groups. The experimental grassland site
                      had 86 plots with different combinations of numbers of
                      species (1, 2, 4, 8, 16, and 60) and numbers of functional
                      groups (1, 2, 3, and 4, being grasses, small nonlegume
                      herbs, tall nonlegume herbs, and legumes). In the second
                      year after establishment, increasing species richness
                      reduced soil N03 concentrations (ANOVA, $11\%$ of sum of
                      squares [SS]). The presence of legumes correlated positively
                      with soil N03 concentrations $(17\%$ of SS). The presence of
                      grasses significantly decreased soil N03 concentrations
                      $(11\%$ of SS). Seasonality had no influence on the
                      relationships between N03 concentrations and species
                      richness. Volume-weighted mean DON and TDN concentrations in
                      soil solution correlated negatively with species richness.
                      Nitrogen pools in plant mixture biomass correlated
                      positively with species diversity $(14\%$ of SS), indicating
                      that total N uptake increased with increasing diversity. We
                      conclude that both diversity (either in species or
                      functional groups) and functional composition of grassland
                      mixtures are significant controls of soil and plant N pools.
                      Plant communities with more diverse mixtures are liable to
                      use limiting resources such as N more effectively.},
