| In two agricultural systems with and without animal husbandry the potential to produce renewable energy by digesting slurry and organic residues to biogas were assessed. In comparison to some other methods of energy production by biomass biogas production has the advantage of keeping the nutrients of the substrates within the agricultural system. They can be used as fertilisers. In the investigated system with milk production (0,8 cows ha-1, 8 crops, among them 4 cereals, peas, potatoes and 2 clover grasses with catch crops after winter cereals and peas (see DEUKER et al. 2005), it is possible not only to ferment slurry, but also catch crops and straw of peas and cereals. The methan production potential by digesting only slurry is the equivalent of around... |

| The influence of biogas production in organic farming systems on different agricultural aspects is being researched in a field trial on the research station Gladbacherhof of the University of Giessen. The investigations took place within a whole crop rotation including 7 different crops in 8 years: two years clover grass followed by winter wheat, potatoes, rye, peas, spelt and at last summer wheat with undersown clover grass. Intercrops were sown after winter cereals and peas. This crop rotation is able to feed an average livestock husbandry in organic farming (0.8 cows ha-1). Four different fertilizing systems are being compared: 1) solid manure ploughed under before seeding of crops, 2) slurry spread out in emerging winter cereals or ploughed under to... |

| Elektrogesponnene, organische Nanofasern sind neuartige Träger für flüchtige Signalstoffe zur biotechnischen Regulierung von Schadinsekten im integrierten und ökologischen Landbau. Der Einsatz von Pheromonen im Pflanzenschutz ist als eine umweltverträgliche Alternative zur Verwendung von chemisch-synthetischen Insektiziden oder als dessen Ergänzung bekannt. Die pheromonbeladenen Nanofasern wirken als Dispenser und sollten vom Konzept her eine möglichst kontinuierliche, räumlich und zeitlich gleichmäßige Abgaberate der flüchtigen Signalstoffe ermöglichen. Anforderungen sind, dass die Fasern wetterstabil sind, lang anhaltend funktionieren, einfach und kostengünstig ausgebracht sowie rückstandsfrei abgebaut werden können. Es werden Ergebnisse von... |
