| Biopores have been shown to be enriched with plant available nutrients as compared to the surrounding bulk soil and therefore are considered hot spots for the nutrient acquisition especially in the otherwise nutrient-poor subsoil. As a result of colonization of biopores by earthworms, pore walls are enriched with nutrients. In this study, a first attempt was made to assess the influence of earthworm abundance on both structural pore wall characteristics as assessed with in situ endoscopy and on pore wall C and N contents. Higher earthworm density resulted in higher N contents and significantly higher C contents in biopore walls as compared to the surrounding bulk soil, regardless whether they showed visible earthworm coatings. In the treatment with lower... |

| Senecio jacobaea is a poisonous weed in grasslands of various countries (e.g. Great Britain, New Zealand, Central European states), and the further spread of the species into farmland must be prevented. Due to strong restrictions of curative measures, the prevention of S. jacobaea’s spread is of primary importance for organic farming. To assess the influence of management practice and site conditions on the occurrence of S. jacobaea, we conducted an on-farm survey in the northern and central part of Switzerland. Botanical assessments were carried out on grassland plots with S. jacobaea occurrence and on neighbour plots without S. jacobaea. For these plots, we analysed the soil nutrients and the details of management practice such as type and intensity of... |

| A manutenção dos resíduos vegetais sobre o solo, o tipo de resíduo e sua velocidade de decomposição são de grande importância no estudo da ciclagem de nutrientes. Este estudo foi desenvolvido na área experimental do IAPAR - Pato Branco-PR, onde foram avaliados seis resíduos de coberturas de inverno: tremoço azul (Lupinus angustifolius L.), ervilhaca comum (Vicia sativa L.), aveia preta (Avena strigosa S.), nabo forrageiro (Raphanus sativus L.), centeio (Secale cereale L.) e trigo (Triticum aestivum L.), sob Sistema Plantio Direto (SPD) e Sistema Cultivo Convencional (SCC) em um Latossolo Vermelho aluminoférrico. Foi avaliado: velocidade de liberação de potássio (K), matéria seca remanescente (MSR) em bolsas de decomposição, teor de carbono orgânico... |

| Different strawberry varieties, available from organic propagation at that time were, planted in August 2004 and proofed about their suitability for organic cultivation, each variety was tested with and without biodegradable mulch film. Within the early ripening strawberry varieties ‘Clery’ had a middle yield and was susceptible for infections with leaf spot, losses of plants by Verticillium were seldom. This variety should be planted early to reach enough vigor in autumn. ‘Clery’ has an interesting potential in the phase of higher prices at the beginning strawberry season. ‘Darselect’ ripened shortly before ‘Elsanta’, the yield was lower, but the fruit-size bigger, so the picking could be done more quickly. ‘Elsanta’ showed in this trial under... |

| Cover or catch crops have beneficial effects for soil, water, erosion, etc. If harvested, they also provide feedstock for biogas without competition for arable land. The latter also applies to clover grass ley or other residues on organic farms without ruminants and for manure. With an explorative approach, combining field experiments and data collection of practical implementation, we investigated achievable yields and identified recommendations for practical use. Gross energy yields of cover crops varied between 700 and 2000 m³ methane (CH4) ha-1 in Austria. The energy return on energy invested (EROI) ranges from 4 to 7, if biogas is upgraded and com¬pressed for biofuel use. Therefore, about 1000 m³ CH4 ha-1 are remaining as net energy yield from 4.5 t... |

| Mit erheblichen finanziellen Mitteln fördert die Deutsche Forschungsgemeinschaft (DFG) zum ersten Mal eine Forschergruppe innerhalb der Landwirtschaftlichen Fakultät der Bonner Universität. Nach den Richtlinien der DFG ist eine Forschergruppe ein längerfristiger Zusammenschluss mehrerer, in der Regel an einem Ort wirkender Wissenschaftler zur Bearbeitung einer besonderen Forschungsaufgabe [...]. Trotz des bestehenden günstigen Images von Produkten des Organischen Landbaus muss davon ausgegangen werden, dass die Verbraucher verstärkt Fragen nach der Qualitätssicherung und deren Nachweis für diese Produkte stellen werden. Die Nachweise einer höheren Produktqualität von Erzeugnissen des Organischen Landbaus sind jedoch bislang in der Gesamtheit betrachtet... |

| In Finland, the Kiuruvesi municipality is the pioneer in use of local and organic food (LOF) in the statutory municipal catering services. The LOF strategy is based on territorial approach, and it was adopted as one means of enhancing the attractiveness of the remotely located municipality with unfavorable population development. The local policymakers have been fully committed to the strategy, and this has enabled the consistent development during nearly two decades. The Kiuruvesi case demonstrates the gradual shift of focus in the competitive bidding process from price-based tendering towards anticipatory dialogue and interaction between the suppliers and catering personnel. Over the years the LOF concept has brought about various kinds of food... |

| The effects of a fogging system on the control of the two-spotted spider mite (Tetranychus urticae) were studied in greenhouse cultivation of eggplant, cucumber and strawberry during the period 1999-2006. At the beginning the pest and the phytoseiid predator Phytoseiulus persimilis were released on the crops and then observations were made on the development of the populations of both mites. Fogging system effects were found in terms of lowering the T. urticae population and hindering the growth of powdery mildew fungus. Furthermore there was a yield increase in the cases of strawberry and cucumber in 2001 but no negative impact on pest management was ever detected, particularly on the biological control of the melon aphid (Aphis gossypii) achieved using... |

| A screening among more than 800 accessions, belonging to more than 100 species was performed in the frame of an international cooperative research program from 2012 to 2016. Aim of the screening was, to identify new species and suitableaccessions, suitable as cover crops and living mulches in Mediterranean, temperate and more continental climates. In this contribution, results obtained in southern Germany are reported, focusing on potential new cover crops. Several new cover crop species could be identified, which were characterized by high biomass production ad weed suppression, as well as by good seed production. Both species and accessions with early and late growth cycle could be identified. |

| Fifty spring barley varieties grown under organic as well as conventional growing conditions in experimental fields in four combinations of year and site were studied. The yield varied much within and between environments (years and sites) and systems. Further, the variation between varieties was substantially and it differed between different environments and systems. Associations between observed grain yield of these varieties and disease and growth characteristics assessed in the official conventional variety testing were compared between the organic and the conventional system. Using factorial regression analysis, the best model for predicting the observed grain yield each year from these characteristics the previous year was found. In this model, the... |

| In the regulation claims are divided into two main categories: nutrition and health claims. In the future only claims that are positively pre-evaluated by EFSA are allowed to be used in commercial communication (all means). Regulation will uniform the use of health claims also in berry production in EU and will hopefully increase the awareness on established health benefits of berries. |
