Abstract:
Semi-natural grassland often has a high biodiversity and is therefore of great interest for nature conservation. As the produced biomass is often no longer usable for animal nutrition, mulching without removal of biomass or utilization of the biomass for energy production are new management alternatives. Therefore the effect of cutting and mulching on botanical composition and biomass production of an unfertilized meadow was tested in a long term field experiment and compared with an uncut control where shrubs and trees established. Botanical composition and biomass production did not differ significantly between cutting and mulching treatments. Additionally the suitability of the biomass for heat generation by combustion was tested. Difficulties with ash hightemperature behaviour and with emissions due to the high mineral content of grassland biomass have to be resolved.
