| Aim of the presented study was the comparison of the specific emissions of CO2 equivalents of a legume based and a mineral N fertilised grassland considering the N2O emissions caused by N fertilisation and soil compaction. The field trial was set up on the experimental station “Hohenschulen” in northern Germany with the factors soil compaction, N fertilisation and experimental year. The N2O emissions were affected by an interaction of soil compaction and N fertilisation, especially under moist spring conditions. The specific CO2-equivalent emission per unit energy yield was 67 % higher for the mineral N-fertilised grassland compared to the legume based grassland. |

| An Experiment to examine the nitrogen fluxes after ploughing up and resowing grassland was conducted on the organic experimental station “Lindhof” in northern Germany. The trial was implemented on a uniform grassland site (since 1993) focussing on the factors grassland resowing, fertilisation with organic cattle slurry (0/230 kg ha-1) and year of renovation (2005, 2006, 2008). The factor grassland resowing further involved the following treatments: 1. undisturbed control, 2. ploughing up and resowing grassland in late summer, 3. ploughing up of grassland in autumn followed by winter wheat and grassland resowing the year after, 4. ploughing up of grassland in spring followed by spring wheat and grassland resowing the year after. Ploughing up in autumn... |
