Summary
Plants can affect N2O emissions by enhancing nitrogen (N) uptake and other below-ground interactions. However, the specific effect of the root systems of different plant species on the production and accumulation of N2O within the soil profile remain largely unknown. The aim of this study was to investigate how plant species from different functional groups, their productivity and root traits affect N2O emissions and N2O concentrations within the soil profile in a fertilised grassland. We conducted a field experiment with two grasses (Phleum pratense, Lolium perenne), two legumes (Trifolium repens, Trifolium pratense), two forbs (Cichorium intybus, Plantago lanceolata), and the six-species mixture in a fertilised grassland. The effects of these plant communities on N-cycling processes were
