Última Futterwirtschaftliche Konsequenzen adaptierter Nutzungs- und Bestandesoptionen im Kleegras zur Förderung des Bruterfolges von Feldlerchen Organic Eprints Fricke, Thomas; Wolf, Ulrike; O'Halloran-Wietholz, Zita; Wachendorf, Prof. Dr. Michael. A field experiment was conducted to evaluate forage parameters of cutting regimes and species mixtures in grass-clover swards adapted to the breeding behaviour of the skylark (Alauda arvensis) as a representative of ground-nesting birds. We investigated options of a three weeks delayed cut in the second growth period to offer an adequate breeding period and an exalted cut at 14 cm height to motivate a preterm nestbuilding. Both regimes were conducted on swards of a standard seeding mixture and a species rich mixture, respectively. The levels of dry matter yield and forage quality did not always match common trends because of an extraordinary sward development based on early spring drought and partly high weed contents. In this study we present the... Tipo: Conference paper, poster, etc. Palavras-chave: "Organics" in general; Biodiversity and ecosystem services; Farm economics.

Felix; Kuschnereit, M.sc. Sara; Graß, Dr. Rüdiger; Fricke, Dipl.-Ing. agr. Thomas; Wachendorf, Prof. Dr. Michael. As a new utilisation concept for the conservation of ecologically valuable habitats the integrated generation of solid fuel and biogas from biomass (IFBB) was tested on five semi-natural grasslands from typical German mountain areas. Through hydrothermal conditioning and mechanical dehydration grassland silage was separated into a press cake and a press fluid. In anaerobic digestion experiments with press fluids methane yields of 304 to 522 normal litre per kg organic dry matter were obtained within 13 days. The specific methane production was higher and went faster compared to the fermentation of the untreated grassland silage. Elemental analyses of the press cakes showed a significant reduction in compounds detrimental for combustion. The ash...
