| Auf 32 Ökobetrieben in Deutschland wurden von 2009 bis 2012 insgesamt 128 Felder untersucht. Ziel war es wesentliche Faktoren für den Boden-Eindringwiderstand zu identifizieren und die Beziehung zwischen Eindringwiderstands-Parametern und dem Ertrag von Wintergetreide zu prüfen. Auf ca. einem Viertel der untersuchten Felder wurden häufig stark verdichtete Bodenschichten gefunden. Korrelationsanalysen ergaben als wesentliche Faktoren eines großen Eindringwiderstands im Untergrund einen hohen Sandanteil, Flachgründigkeit von Böden, warme Temperaturen, niedrige Kleegras- und Winterfruchtanteile sowie hohe Anteile an Kartoffeln in der Fruchtfolge, große Pflugtiefen und hohe Schleppergewichte. Partielle Korrelationsanalysen ergaben negative Beziehungen zwischen... |

| Legume foot and root diseases are influenced by complex interactions of site, soil properties, seed health, cropping sequence and climate. Crop rotation, cover crops and organic matter management are the key management tools in the dealing with the increase pathogen pressure. Application of high quality composts and other organic amendments is potential ecologically friendly alternative to fungicide application for control of soil-borne fungal pathogens. In order to evaluate the potential of Yard Waste Compost (YWC) to suppress foot rot disease of pea caused by Didymella pinodes (syn Mycospharella pinodes), Phoma medicaginis, Fusarium solani f. sp pisi and F. avenaceum, a pot experiment was carried out under controlled conditions. The susceptible spring... |

| Fertile soils are highly important for arable farming. To maintain soil fertility, crop rotation including legumes is applied, particularly in stockless farms. Yet, many commercial farms report yield reductions for legumes. The aim of the present study was to evaluate whether the causes for the observed soil fatigue can be narrowed down by a bioassay (modified differential diagnosis according to Bouhot) and whether this bioassay could be a useful tool to predict the suitability of a field to grow legumes. |

| Suppressive effects of composts have been demonstrated mainly by American scientists with composted hard-wood bark as a part of container media for ornamentals. In this paper we report about experiments with yard waste- (YWC), biogenic waste- (BWC) and cattle manure compost (CMC) towards the soil borne pathogen Pythium ultimum Trow. There are results included from model composting systems and from yard waste composts originating from two commercial composting plants (C-YWC). It was shown that, in comparison to the other tested composts, YWC from the model composting system was superior in reducing disease incidence caused by P. ultimum on peas. In fifteen cases out of eighteen experiments with addition of 15 % compost the amendment of YWC resulted in... |

| The project CO-FREE (2012-2016) aimed to develop strategies to replace/reduce copper use in organic, integrated and conventional farming. CO-FREE alternative test products (CTPs) were tested and integrated together with decision support systems, disease-tolerant varieties, and innovative breeding goals (ideotypes) into improved management strategies. CO-FREE focused on apple/apple scab (Venturia inaequalis), grape/downy mildew (Plasmopara viticola), and tomato and potato/late blight (Phytophthora infestans). Starting point of the project were ten CTPs with direct or indirect modes of action including Trichoderma atroviride SC1 and protein extract SCNB, Lysobacter spp., yeast-based derivatives, Cladosporium cladosporioides H39, the oligosaccharidic complex... |

| Potatoes are one of the most important crops in organic farming with respect to farmers’ income. Yields are often strongly influenced by regional and yearly diffe-rences. Despite the availability of detailed knowledge, it is only now that a crop growth model has been generated which allows for the estimation and prediction of potato yield under organic conditions. The aim of our study was to produce a highly elaborate prediction model based on the utilization and speed of nitrogen uptake as they relate to the yield dynamics of tubers and canopy in combination with late blight dynamics. Therefore, from 2005 to 2014, these parameters were assessed in up to 18 varieties of potatoes comprised of differing maturity groups. The data were ana-lyzed in R using... |

| Experiments were conducted to determine how tillage intensity, the use of biofumigation brassica cover crops and mixed cropping with oats affect the performance of organic peas with respect to weed pressure, diseases, and yield. Fields were either ploughed to a depth of about 15-20 cm or only to about 8 cm in late summer followed by either Sinapis alba (low glucosinolate (GSC) content), Raphanus sativus (medium GSC) or Brassica juncea (high GSC). Brassicas were mulched in fall right before flowering and incorporated in the top soil. In mixtures with oats seed rate for peas was as in pure stands, for oats it was 20 %. There was a dramatic spring drought in 2011 resulting in severe water stress for the peas in 2011. Weeds were significantly reduced by about... |

| Reduced tillage combined with about 10cm of fresh mulch of a mixture of green peas and rye was compared to a system with conventional tillage with a plow for its effects on disease development of Phytophthora infestans. Within tillage treatments the precrops for potatoes were weedy fallow, vetch (Vicia sativa), or a mixture of oilseed radish and black oats with or without compost application. The Area Under the Disease Progress Curve in the minimum tillage and mulched plots was on average 881 while in the plowed plots it was 1336, a highly significant difference. Yield data are currently being analyzed and will be presented. |

| The impact of soil type, long-term soil management, and short-term fertility input strategies on the suppressiveness of soils against soil-borne (Ocimum basilicum – Rhizoctonia solani, Lepidium sativum – Pythium ultimum) as well as air-borne (Lycopersicon esculentum – Phytophthora infestans, Arabidopsis thaliana – Hyaloperonospora parasitica) diseases was studied. Soils from field trials established in five European sites with contrasting pedo-climatic conditions were examined. Sites included (i) a long-term management field trial comparing organic and conventional farming systems (DOK-trial, Therwil, Switzerland) (ii) a short-term fertility input field trial comparing mineral and organic matter fertilisation regimes (Bonn (BON), Germany) (iii) two... |

| The EU project OSCAR (“Optimising Subsidiary Crop Applications in Rotations” [http://www.oscar-covercrops.eu]) aims to achieve comprehensive advances in conservation agriculture to improve sustainability of low-input, organic, and conventional farming systems. The research integrates living mulches, dead mulches, or cover crops with the main crops in rotations so as to simultaneously improve crop nutrition, health, and productivity. Coordinated field experiments in addition to three long-term experiments take place in different climatic regions in Europe and Brazil. Economic and ecological impacts including legume root health will be investigated. Private breeders and manufacturers of agricultural equipment are involved in finding adapted solutions by... |

| Three potato varieties – Nicola, Rosella, and Simone, differing in the time of initiation of tuber formation (early, middle, late, respectively) – were grown in a 3-factorial field trial for two years in 2 rotational positions i. e. after grass clover and winter wheat in order to induce a different fertility status. A copper control was included. Nitrogen supply after grass clover was between 26 to 32 kg higher than after winter wheat. Late blight severity was high in 2002 but almost nil in 2003 (Area under the curve 1100 versus 75, respectively). In both years, it was consistently but not significantly higher after grass clover. N-mineralisation rates in 2002 were below average due to unfavourable weather conditions in May and June. Thus, only in 2003 the... |

| In organic agriculture legumes build the basis of soil fertility. A diminution of the legumes´ performance not only restricts their own yield but also the yield of the whole crop rotation. However, legumes – especially peas – are strongly affected by soil-born diseases and react sensitively to soil compaction. Aim of the study is to gain knowledge about the interaction of differentiated soil compaction on soil physical parameters and the yield of peas in a sole- and mixed cropping system with oat. We conducted field trials at four different sites where plots were passed with a wheel load of 2.6 t and 4.6 t before seeding. Results show that bulk density in the topsoil increased significantly with increasing wheel load, while soil porosity decreased.... |

| Genetische Vielfalt und das Mikroklima innerhalb eines Feldes kann die Entwicklung von Epidemien massiv beeinflussen. In Kartoffelbeständen kann Vielfalt durch Sortenmischungen in der Reihe, alternierenden Reihen oder Streifen verschiedener Sorten (siehe Finckh et. al. 2003, dieser Band) oder im Streifenanbau abwechselnd mit anderen Kulturen erreicht werden. Beim Streifenanbau mit verschiedenen Kulturen sind eine große Anzahl Anbaufaktoren beeinflußbar wie Feldlänge und - breite, Ausrichtung zum Wind und die Art der Nachbarkulturen. Diese können, wenn sie höher als die Kartoffelbestände sind als Barrieren für Wind und Krankheitsinokulum dienen, eventuell aber auch die Bestandesfeuchte erhöhen. Niedrigere Kulturen dagegen können die Bestandesfeuchte... |

| In an EU CRAFT project (COOP-CT-2004-508458) running from March 2004 to March 2006, an international consortium of producers of environmen-tally benign crop inputs (BFPs: Biological Food for Plants), RTD performers and end users, evaluated the production and use of BFPs manufactured from differ-ent raw materials: bovine hides, trees, and herba-ceous species. At the manufacturing level, production methods and procedures were reviewed to establish possible relationships between processing steps and end-product quality. At the field level, the BFP prod-ucts were applied as solid pellets or liquids, as fertil-isers or sprays, respectively, on organically grown potatoes and tomatoes and conventionally grown watermelon, cauliflower, strawberries, black currant,... |
