| In order to produce high quality forages, the species composition of the grass sward is of special importance. A good measure for estimating the quality of grass swards is the so-called mean Futterwertzahl of the sward by Klapp (1965) which is further referred to as Sward Quality Index (SQI). On 56 organic farms the average SQI of the farm has been calculated and the yield proportion of different species of the sward has been calculated for different regions of Northwest Germany. Within 22 organic farms with grassland farming exclusively, a comparison of the milk yields (kg ECM/cow and year) and the mean SQI of the grassland has been calculated with special regard to the concentrate rates fed to the cows. In tendency the results show lower SQI in farms... |

| The knowledge about Lucerne as part of the grass sward in systems with intensive grazing is limited, therefore some additional registration has been made both in year 2007 when the sward was established and during the period of utilization in 2008 (Table 1). As seen, is the proportion of Lucerne in 4 of the farms both in May and August at a very low level. |

| In der ökologischen Grünlandbewirtschaftung werden artenreiche Bestände mit Standort angepassten und möglichst wertvollen Futterarten angestrebt. Dennoch sind in der Praxis oftmals stark Weidelgras betonte Bestände anzutreffen. Im Vergleich zur Neuansaat sind Nachsaaten deutlich kostengünstiger. Daher wurden im Sommer 2007 auf 8 ökologisch bewirtschafteten Betrieben Nord-Westdeutschlands Nachsaatversuche mit unterschiedlicher Technik (Schlitzsaat und Bandfrässaat) und ausgewählten Arten angelegt. Hierbei würden 5 Gramineen (Lolium perenne, Phleum pratense, Festuca rubra, Dactylis glomerata) und auf drei Standorten in Niedersachsen zusätzlich Festulolium, eine Neuzüchtung aus Festuca- und Lolium-Gattungen sowie eine Futterleguminose (Lotus corniculatus)... |

| Negativa K-balanser har rapporterats från vallintensiva ekologiska odlingssystem både i Sverige och andra europeiska länder. De rapporterade negativa kaliumbalanserna är oftast beräknade för hela växtföljden. Om en kaliumbalans för de enskilda grödorna beräknas så ser man att för vissa grödor som t.ex. spannmål är kaliumtillförsel och bortförsel i balans eller så finns ett överskott av kalium. Vallgrödorna däremot har ofta ett stort kaliumunderskott. I ekologiska odlingssystem är en kontinuerlig leverans av K genom mineralvittring av stor betydelse för en bevarad långsiktig produktionsförmåga. Detta studerar vi inom det Formas-finansierade projektet "Kvantifiering av mineralvittringens bidrag till grödornas kaliumförsörjning på olika typer av... |

| The main objective of the 4-year project was to provide both qualitative and quantitative information on the development of two contrasting organic dairy systems, including the benefits and limitations of each system and also the opportunities for improving the systems. The first system (SS system) was based on an extensive and sustainable system, with the objective of achieving a high level of self sufficiency and sustainability by minimising the importation of nutrients into the system. Therefore, the cropping rotation for the system included forage crops for grazing and conservation and also cereal crops to provide both grain (for feeding as a concentrate) and straw for bedding. The main objective of the second system (PC system) was to change from a... |

| In einem Feldversuch mit vier Nachsaatvarianten wurde der Einfluss der Faktorkombination Pflanzengesellschaft und Bodenbeschaffenheit auf den Ansaaterfolg der Arten Deutsches Weidelgras (früh, mittel und spätblühende Sorten) und Wiesenschweidel (früh blühend) geprüft. Parallel wurde ein Gefäßversuch im Gewächshaus durchgeführt, um die Anfangsentwicklung einer Nachsaat über Auflaufraten und Wuchshöhen besser dokumentieren zu können. Als Faktoren dienten hier die Art (Deutsches Weidelgras Lipresso, Wiesenschweidel Perun) und die Narbe (ohne bzw. mit Konkurrenz). Im Feldversuch konnte der signifikante Einfluss der Bodenbeschaffenheit und der daraus resultierenden Pflanzengesellschaft auf den Nachsaaterfolg nachgewiesen werden. Verfilzte Narben, Beschattung... |

| Herbs are established in many organic grasslands due to expected beneficially properties of nutritive value and biodiversity. However, knowledge about grassland herbs is limited. Three mixtures were therefore established at different grazing/cutting management and slurry application. The competitiveness of the species varied very much. Plantain (Plantago lanceolata) and lucerne (Medicargo sativa) competed best under cutting, opposite chicory (Cichorium intybus) that competed best under grazing. Caraway (Carum carvi), burnet (Poterium sanguisorba) and lotus (Lotus coniculatus) had a relative low competitiveness. Slurry application did not affect the proportion of non-leguminous herbs. The nutritive value differed very much. Caraway had the highest and... |

| Nitrous oxide (N2O) is a potent greenhouse gas with a high contribution from agricultural soils and emissions that depend on soil type, climate, crops and management practices. The N2O emissions therefore need to be included as an integral part of environmental assessment of agricultural production systems. A dynamical algorithm for N2O production and emission from agricultural soils was developed and included in the FASSET whole-farm model. The model simulated carbon and nitrogen (N) turnover on a daily basis. Both nitrification and denitrification was included in the model as sources for N2O production, and the N2O emissions were simulated to depend on soil microbial and physical conditions. The model was tested on experimental data of N2O emissions from... |

| En grøn foderration med brug af urter i græsblandingerne gør det muligt i højere grad at blive selvforsynende med vitaminer og mineraler. Et forsøg med to økologiske fodringsstrategier har vist, at køer der ikke får tilskud af mineraler, men derimod får en foderblanding med et højt indhold af naturlige mineraler og vitaminer, har samme foderoptagelse, mælkeproduktion og reproduktion, som køer på en mere traditionel foderration. Blodprøver viste desuden, at køer, der udelukkende fik mineraler og vitaminer naturligt indeholdt i de forskellige fodermidler, havde samme A- og E-vitaminniveau i blodet, som køer der fik tilsat mineralblanding til foderet. |

| Within a schedule of long-term organic forage crop rotations, two mixed stands of ryegrass-clover were evaluated as following crops after winter cereal-legume mixtures under different sowing and tillage methods in Asturias (N. Spain). Significant differences were found in productivity, sward components, chemical composition and in growth dynamics. The crop sequence perennial ryegrass-white clover established under a triticale-field bean canopy produced an additional 6 t DM/ha, compared with oat-vetch followed by Italian ryegrass-red clover under regular post-harvest sowing, thus being a promising method for improving organic forage productions with minimum tillage. Changes in productivity and feeding values observed for both these ryegrass-clover swards... |

| In many organic grasslands herbs are established due to their expected beneficial properties for nutritive value and biodiversity. However, knowledge about grassland herbs is limited. Three mixtures were therefore established at different grazing/cutting and fertilization managements to examine the growth potential and feeding value. The competitiveness of the different species varied greatly. Chicory, plantain and caraway were competitive in mixtures with traditional grassland species. Lotus and salad burnet were weak competitors and chervil and sainfoin were very weak. The feeding value was also highly variable. Caraway had high digestibility of organic matter, also compared with the traditional grassland species, whereas plantain and salad burnet had... |
