| Grain legume-cereal intercropping is a method to obtain greater and more stable crop yields, improve the plant resource utilisation (water, light, nutrients), increase the input of leguminous symbiotic nitrogen fixation (SNF) to the cropping system and reduce negative impacts on the environment. However, due to agricultural intensification of plant breeding, mechanisation, and fertiliser and pesticide use over the last 50 years, intercropping has disappeared from many European farming systems. Motivations for reintroducing grain-legume-cereal intercropping relate to the problems faced by intensive farming systems. During the 1980s it became evident that West European agricultural production systems (often characterised by monocultures, nutrient... |

| Differences in nutrient availability and methods of pest management may affect crop growth and product quality. The question is whether conventional and organic cropping systems, which differ clearly in strategies for nutrient and pest management, influence the harvest and sensory quality of the products? With the aim to elucidate this question, lettuce and onion were grown in a conventional and three organic cropping systems with increasing levels of nutrient re-cycling and use of intercrops for natural pest management in the period of 2007-2009. The conventional and first organic system relied fully on external inputs in the form of NPK or liquid manure for nutrient management, respectively. In the second organic system, low external inputs of liquid... |

| The improvement of organic fertilization practices is essential to increase organic potato production in the highland region of NW Portugal, with environmental benefits and better returns. For that reason, the response of organic potato was evaluated throughout a randomized block design experiment, with two cultivars (Raja and Virgo) and increasing rates of composted organic pig manure (0, 15, 30 and 45 t ha-1). These cultivars were also grown with mineral N fertilizer (120 kg N ha-1) under conventional practices to compare the results between crop systems, 30, 45, 60, 80 and 125 days after planting. Crop yield was not improved with increasing rates of compost application because the N mineralization rate of the compost was small and soil organic matter... |

| Grass-legume mixtures characterized by high productivity, efficient nitrogen (N) use and strong weed suppression were proposed to increase sustainability of grassland production. Adding competitive forbs to grassclover mixtures can be expected to further enhance the high productivity of grass-clover mixtures. This study investigates whether and to what extent adding forbs to a grass-clover mixture results in yield gains, and estimates the contributions of forb species (identity effect) and interactions with the grass-clover mixture (diversity effect) to these gains. It further examines the effectiveness of weed suppression in forb-containing grass-clover mixtures. Fifteen pure and mixed stands, all comprising the grass Lolium perenne L. and the legume... |

| In this project, located at Winklhof, a comparison between organic and conventional farming is done. The field trial combines a crop rotation with two levels of fertilisation intensities (one is 1.0 LU ha- and the other is 1.8 LU ha-1). The fertilisation-systems are stable-manure and liquid manure, the treatments were done organically. The aim of this project is to find out which production system is better for the environment in spite of crop yield, product quality and leaching losses. The last parameter was measured in lysimeters. A high amount of yearly precipitation could account the high amount of seepage water. Consequently the leaching losses of both production systems could be compared. |

| Agriculture has transformed over the past centuries dramatically to become highly dependent on non-renewable fossil fuels, synthetic fertilizers and plant protection agents. This often occurs at the cost of soil degradation and soil food web disturbance. Future agriculture must not only be productive but also provide ecosystem services such as carbon sequestration, pest and disease suppression, nutrient cycling and water storage to become sustainable in the long-term. Sustainability is especially fostered by reduced tillage and the presence of a permanent layer of plant residues. Under such conditions, soil compaction is reduced, soil structure improved, water infiltration enhanced, soil organic content increased and microbial activity stimulated. However,... |

| Im ökologischen Landbau stellen der Beikrautdruck, die N- und Humusversorgung zentrale Probleme der Fruchtfolge dar. Ertrag, Ertragssicherheit und der Pflegeaufwand werden davon direkt bestimmt. Leguminosenhaltige Grünbrachen in der Fruchtfolge mindern besonders den Unkrautdruck und verbessern die Humusbilanz. Ihre N-Wirkung fällt dagegen bisher unbefriedigend aus, da der oft kurzfristig hohe N-Bedarf der Gemüsepflanzen nicht gedeckt werden kann. Auch über Winter abfrierende Gründüngungspflanzen zeigen oftmals nur eine schwache Düngerwirkung, weil die Gemüsepflanzen nur ein geringes Wurzelsystem haben, das keinen Zugang zu dem tiefer im Boden verlagerten Stickstoff hat. Es soll deshalb untersucht werden, ob durch den Anbau einer Gründüngung in Verbindung... |

| Danish experiments with cereal-based organic crop rotations have shown that the short-term results (the first course, up to four years after conversion) are different from those obtained in the longer-term (the second course, fifth to eighth year after conversion). Yield gain from use of manure increased from the first to the second course on a sandy soil, but decreased on loamier soils. Yield gain from leguminous catch crops increased from the first to the second course in a crop rotation without grass-clover. Some of these effects were caused by buffering effects of the grass-clover, other effects were caused by changes in soil fertility over time. |

| This paper discusses some relevant agronomic aspects related to the productivity of organic farming systems (OFS). In a first step some key requirements to ensure the validity of comparative studies including the consideration of rotation yields and the use of representative amounts of organic inputs are defined. A main chapter is dedicated to the potential of biological nitrogen fixation to substitute mineral nitrogen, which currently covers an estimated third of the total nitrogen input to agricultural field with increasing tendency. To bring forward OA as a sustainable method of food production with high process quality, it is suggested to focus rather on a large scale organic vegetable and fruit production than on global supply of calories and protein. |

| Increasing plant diversity in grasslands may improve productivity and yield stability. This study investigates in a field experiment, yield and quality of two-species swards of ryegrass/white clover and three-species swards of ryegrass/white and red clover at five different managements representing cutting, grazing, combinations of cutting and grazing and different fertilizer treatments in 1 to 4-yr-old swards. Generally, the three-species mixture produced higher yields than the two-species mixture when swards were young and lower yields when swards were 3 and 4 years old. Fertilizer responses were similar in both mixtures and also rather independent of sward age. The overall mean annual yield increase by slurry application was 1.34 t DM corresponding to... |

| Im Feldversuchen wurde die Wirkung von Zwischenfruchtgemengen in Bezug auf das N-Bindungsvermögen des Aufwuchses, auf die N-Gehalte im Boden während der Winterperiode sowie den Ertrag und die Qualität nachfolgend angebauter Speisekartoffeln untersucht. Während unter den Zwischenfruchtparzellen nur eine vergleichsweise geringe Verlagerung des mineralischen Stickstoffs in tiefere Bodenschichten zu beobachten war, kam es in der Kontrollvariante zu teils deutlichen Verschiebungen. Die Variante ohne Zwischenfrüchte wies im dreijährigen Mittel den tendenziell niedrigsten Knollenertrag auf, während nach der Winterzwischenfrucht Landsberger Gemenge der signifikant höchste Ertrag gemessen wurde. Einflüsse der Zwischenfruchtgemenge auf Gesundheitsstatus oder... |

| Jordbearbetning är en effektiv kontrollmetod mot perenna ogräs, såsom kvickrot (Elymus repens L.), delvis på grund av att bearbetningen sönderdelar ogräsens underjordiska lagringsorgan (rhizom). Jordbearbetning ökar dock risken för näringsläckage, och det är svårt att kombinera jordbearbetning med en växande gröda. I denna studie använde vi oss av en prototyp med vertikala diskar för att fragmentera kvickrotens rhizomer med minimal störning av jord och gröda. Målet var att utveckla en metod för kvickrotskontroll i gräs-klövergrödor med en kombination av rhizomfragmentering och putsning. Experimenten utfördes 2014 och 2015 i Uppsala, med rhizomfragmentering utförd innan sådd (TRF), i den växande grödan (SRF) eller både och (TRF + SRF).... |
