| The content of sulphur (S) in grassland on 27 Norwegian organic farms with dairy or sheep production was investigated in 2001 and 2002. The forage content of S was below the norms (2 g S kg DM-1) for both plants and animals in a large proportion of the samples. The average S content in forage at dairy farms was 1.4 g S kg DM-1 and at sheep farms 1.5 g. Even on grasslands with low plant S content (<1 g S kg DM-1), S-fertilization did not increase yields and increased the plants’ S content only very slightly. No indications of S deficiency were observed on the dairy farms. For one sheep farm with a forage S content of 1.1 ± 0.1g S kg DM-1, brittle and short winter wool was reported. |

| The extraction of proteins from leaves, integrated in a green biorefinery, may represent an attractive solution to the increasing demand for protein-rich animal feeds while decreasing the dependency on soybean imports. Thereby such green biorefineries could contribute to the development of more self-sufficient and sustainable agricultural systems in Europe. The framework of this PhD study is a green biorefinery concept for the production of protein concentrate, biogas and fertilizer from organic and locally grown green crops like alfalfa, clover or grass. After the screw pressing of the fresh crops, lactic acid fermentation of the green juice with Lactobacillus salivarius BC 1001 was assessed as the key method for the recovery of proteins. A leaf protein... |

| The agronomic performance, biological nitrogen fixation (BNF) ability and self-establishment potential of seven species of annual self-reseeding legumes were investigated in Apulia region, Italy. For the first cropping cycle (2005-2006) preliminary results showed that Trifolium spp. performed better than Medicago spp. Among the seven species, five were more suitable to the site’s conditions. T. angustifolium and M. polymorpha gave the best results. T. angustifolium fixed 131.7 kg ha-1 year of nitrogen (15N isotope dilution method), produced 1976 kg ha-1 of seeds and 8.7 t ha-1 of dry matter (DM). M. radiata and M. rigidula were the less performing. During the second cropping cycle (2006-2007) results showed that Trifolium spp. self-established better than... |

| Intresset för åkerböna (Vicia faba L.) har ökat de senaste åren, både inom konventionell och ekologisk odling. För att nå ett uthålligt växtodlingssystem är ärter och åkerbönor intressanta genom sin kvävefixerande förmåga, inte minst i ekologiska system. Ärter kan drabbas av ärtrotröta om de förekommer för tätt i växtföljden, varför åkerböna är ett alternativ. Att nå mogen skörd med åkerböna kan vara ett problem, utom i de sydligaste delarna av landet. Alternativet är då att skörda den som helsädesensilage, gärna i samodling med spannmål. Syftet med forskningsprogrammet är att ge underlag till optimal skördetid för helsäd av spannmål och åkerböna. Projektet ska också utvärdera grödans fodervärde och avkastning, samt ensilerbarhet. Projektets huvuddel... |

| Effects of wilting, ensiling and type of additive on atocopherol and b-carotene contents in legume–grass mixtures were examined. Swards of birdsfoot trefoil + timothy (Bft + Ti), red clover + timothy (Rc + Ti) and red clover + meadow fescue (Rc + Mf) were harvested as a first regrowth in August 2005. Forage was wilted to a dry-matter (DM) content of 273 g kg)1 and ensiled without additive or with an inoculant or acid. Wilting decreased a-tocopherol concentration by 30% in the Bft + Ti mixture (P = 0x015). Untreated Bft + Ti silage had higher a-tocopherol content than red clover silages (56x9 vs. 34x2 mg kg)1 DM; P = 0x015). The a-tocopherol concentration of Bft + Ti silages increased during ensiling from 41x1 mg kg)1 DM in wilted herbage to 56x9, 65x2 and... |

| Ampfer breitet sich im ökologisch bewirtschafteten Grünland zunehmend aus. Das Institut für ökologischen Landbau der Bundesforschungsanstalt für Landwirtschaft in Trenthorst führte daher im Rahmen eines Projektes des Bundesprogramms Ökologischer Landbau Versuche zur Regulierung von Ampfer im Grünland durch (Direkte Kontrolle mittels manuellem Ampferstechen, maschinellem Ampferstechen mit der Wurzelziehmaschine WUZI und Abflammen jeweils mit und ohne Nachsaat sowie Auswirkungen des Beweidungsmanagements) und befragte bundesweit 156 ökologisch wirtschaftende Landwirte. Die Umfrage zeigte, dass fast die Hälfte der Betriebe Probleme mit Ampfer im Grünland haben, bei weiteren zwanzig Prozent sind diese Probleme sogar besonders gravierend. Jeder Betrieb hat auf... |

| This work studied the anaerobic digestion of brown juice, a liquid residual stream generated from biomass fractionation in a green biorefinery. Biomethane potential batch tests and inhibition studies of brown juice were performed during continuous processing in an upflow anaerobic sludge blanket reactor. Prolongation of the lag phase in the batch tests with increasing substrate/inoculum ratio suggested initial inhibition, which was, however, overcome by adaptation. This was indicated by high final methane yields, which were close to the theoretical maximum of up to 500 L-CH4 kg-VS−1, achieved after 15 days for most of the set-ups. Reactor operation at the organic loading rate of 13.9 g-COD L−1 day−1 and hydraulic retention time of 3 days revealed methane... |

| Soil fertility management is a major concern in organic farming. According to the EEC Regulation 2092/91, soil fertility must be maintained and/or increased by legumes cultivation. Native Mediterranean legumes ecotypes are more persistent than commercial varieties but their use in catch crop sequences is still limited. The N2-fixing legumes crops as a local resource can be considered as an alternative to improve nitrogen nutrition and to increase crop yields. This study aimed to investigate the agronomic performance of seven annual self-reseeding legumes and the short–term effect of nitrogen supply on the subsequent crops. Results are presented from field experiment on sandy-clay soil, pH 8.1 and 1.6% of organic matter, in the south of Italy, where the... |

| Lactic acid bacteria (LAB) have extensive industrial applications as producers of lactic acid, as probiotics, as biocontrol agents and as biopreservatives. LAB play a large role in food fermentation and in silage processes, where crops such as grass, legumes, cereals or corn are fermented into high-moisture feed that is storable and can be used to feed cattle, sheep or other ruminants. LAB also have great applications within green biorefineries, with simultaneous production of protein-rich feed for monogastric animals, silage or feed pellets for ruminants and production of lactic acid or specific amino acids. In green biorefineries, fresh or ensiled wet biomass is mechanically fractionated into green juice and solid residues (press cake), where the plant... |

| Die Kurzrasenweide ist ein geeignetes Weidesystem für die Low-Input Milchviehhaltung und daher auch für die Biologische Landwirtschaft interessant. Weidehaltung bietet nicht nur wirtschaftliche Vorteile, sondern passt auch ideal zu den Werten der Biologischen Landwirtschaft. Bei der Umstellung eines Milchviehbetriebes auf ein Weide basiertes Fütterungssystem müssen vorher als Mähwiesen genutzte Flächen beweidet werden. Durch die Bewirtschaftungsänderung von einer Schnittwiese zur Kurzrasenweide sind Auswirkungen auf den Pflanzenbestand sowie auf die Mengen- und Qualitätserträge zu erwarten. Um diese Hypothesen zu überprüfen, wurde ein 3-jähriger Feldversuch am Bio Lehr- und Forschungsbetrieb des LFZ Raumberg-Gumpenstein von 2007-2009 angelegt. In dieser... |

| The consequences of a late closing date in autumn on pasture performance in spring are mostly unknown under Mid-European climatic conditions. An experiment on two sites in the Swiss lowlands showed that a delay of the closing date from early October to late November reduced spring yield by 50% (238-821 kg DM/ha) in early April and 18% (556-986 kg DM/ha) in Mai. This reduction of spring yield was particularly high (up to 75%) if the residual herbage mass before winter was below 300-500 kg DM/ha. On the other hand residual herbage mass above this threshold did not increase spring yield considerably. Thus, the utilisation of pasture in late autumn is recommended, if conditions are favourable and if grazing does not reduce the residual herbage mass below... |
