“…The fact that no difference in legume cover was found between the unfertilized control and PK fertilization treatments contradicts the findings for montane grasslands, where legumes benefited from PK fertilization compared to unfertilized controls [91].…”

The Dessau Grassland Experiment—Impact of Fertilization on Forage Quality and Species Assembly in a Species-Rich Alluvial Meadow

Since alluvial meadows of river valleys of the Cnidion dubii are protected by the EU Habitats Directive, reconciling farmers’ demands for forage quality with the objective of maintaining them in good conservation status is an important issue in grassland research. In a long-term experiment from 2010 to 2018, we investigated the impact of fertilizing on forage quality and species assembly on a species-rich and twice-mown alluvial grassland in the Dessau Elbe floodplain (Germany). The experiment was composed of an unfertilized control, PK, N60, N60PK and N120PK applications. A significant improvement in forage quality was achieved by nitrogen fertilization only for crude protein, with higher feeding requirements for sheep met only in individual years. The legume cycle was inhibited by the application of nitrogen and high grass cover was maintained, but not increased, at the highest nitrogen application after an exceptional summer flood. The target forbs persisted in numbers over the study period in all treatments. For cover, the low-competitive target forbs responded neutrally to nitrogen fertilization, whereas detrimental effects were demonstrated for the competitive ones. Thus, we recommend not applying more than 60 kg year−1 of nitrogen and only in combination with phosphorus and potassium.

“…However, after four decades of utilization of these areas, the quantity and quality of forage had become key constraints to the development of the livestock sector (Maticic, ). A chronic deficit in high‐quality protein was caused by poor grassland management (Holúbek & Petrovič, ; Hrazdira, Koníček, & Tomka, ; Tomka & Šanta, ) and by a subsidy policy that made concentrate feeding more attractive than using grass.…”

Throughout Europe, grasslands are managed primarily for agricultural production but also provide a range of ecosystem services, the magnitude of which is influenced by their area, management and the abiotic properties of the ecosystem. The grassland area in Europe has been affected by significant changes in recent decades, including abandonment and conversion to arable land. This study presents an assessment of changes in the permanent grassland area with reference to Slovakia and provides an assessment of the bioenergy potential of permanent grassland surplus to agricultural needs. In 2015, of the total permanent grassland area (868,000 ha) 42% had ceased to be used as feed for milk or meat production and had been abandoned. Results from field experiments show that low-level improvement of permanent grasslands, e.g., by oversowing commonly sown agricultural grassland species and low-dose fertilization (up to 30 kg N ha À1 year À1) could provide herbage biomass of 1.7 million tonnes of herbage dry matter per year. This would be sufficient to generate an energy output of approximately 31.3-31.9 PJ/year (4.5% of the current gross inland energy consumption of Slovakia). Low-intensity use of the currently surplus permanent grassland is also considered to have potential beneficial outcomes in terms of delivery of ecosystem services. Results are also discussed in the context of countries beyond the case-study area.
