| Field pea (Pisum sativum L.) and spring barley (Hordeum vulgare L) were intercropped and sole cropped to compare the effects of crop diversity on the use of nitrogen sources in European organic crop-ping systems. Across a wide range of growing condi-tions pea-barley intercropping showed that nitrogen sources were used from 17 to 31% more efficiently by the intercrop than by the sole crops. Intercropping technologies offers the opportunity for organic cropping systems to utilize N complementarity between component crops, without compromising total crop N yield levels |

| Vegetables with a high nitrogen demand such as cauliflower may cause intensive leaching of nitrate to the environment in conventional as well as in organic production. In organic cropping systems, the use of an in-season living mulch may decrease the risk of nitrate leaching after harvest when left growing in the field to the end of the leaching season in spring. The aim of this study was to investigate the effect of growing an in-season living mulch including legumes on the risk of leaching of inorganic nitrogen over winter, and soil nitrogen availability the following spring. Three field experiments were carried out in Slovenia, Germany and Denmark in the frame of the Interveg project (CORE organic II). Evaluation of soil inorganic nitrogen content was... |

| Group members came from 12 European countries, six from new (Bulgaria, Czech Republic, Estonia, Hungary, Poland and Slovenia) and six from old EU member states (Germany, Spain, Finland, Italy, The Netherlands, Portugal). The aim of the work was to analyze the role of the scientists in a dialogue between them and the practitioners within the organic production sector. Another important aim was to find the best practice models of such dialogue as the examples to be followed by others. In order to reach this aim the survey with the scientists has been conducted by all project partners; every partner has conducted the survey with 10 selected scientists from own country. Only the scientists possessing PhD level and actively working in the organic sector... |

| The aim of this study was to evaluate the effect of cover crops on pest/beneficial dynamics and to test the potential of living mulch on enhancing biological control against insect pests. The research, carried out in the frame of the InterVeg (Core Organic II) project, involved four European countries: Germany, Slovenia, Denmark and Italy. Three crops were tested: cauliflower, leek and artichoke. The preliminary results obtained in Italy on cauliflower, indicated that the living mulch did not affect the infestation of the cabbage butterfly, Pieris brassicae, showing no detrimental effect of this technique on pest dynamics. A very high level of parasitization against cabbage butterfly was detected either in the living mulch crop (88%) and in the sole one... |

| Das Core Organic II Projekt InterVegi zielt darauf ab, untersaatbetonte Anbausysteme im ökologischen Gemüsebau in Bezug auf Vor- und Nachteile zu untersuchen. Wesentliche Parameter sind dabei Schädling-Nützling-Interaktionen, Aspekte der Beikraut-Regulierung sowie des Nährstoffmanagements, Auswirkungen auf Pflanzenentwicklung, Ertrag und Produktqualität, Umwelteinflüsse sowie ökologische Leistungen auf Feldebene. Hypothese der Untersuchungen ist: Untersaaten in Gemüsekulturen ermöglichen vergleichbare Ertragsleistungen, bessere Produktqualitäten, weniger Einsatz externer Ressourcen wie Pflanzenschutzmittel und Dünger sowie reduzierten Energie-Verbrauch. Dies führt zu Anbausystemen mit weniger Umweltbeeinträchtigung und besserer Profitabilität aufgrund... |

| Within the EU-Project CHANNEL a status quo-analysis on organic agriculture practice was made for all new member countries, including Romania and Bulgaria as new accession countires and Austria and Germany as old member countries. Rotational and nutrient management in crop husbandry was evaluted through ques-tionnaires answered by experts of each country. Examples of typical rotations were proved with regard to duration, share of legumes and distribution of legumes. 21 of 93 rotations were shorter than 4 years and seemed to be very susceptible to unavoidable phytosanitary and compatibility problems. 20 of 93 rotations only con-sisted of non-legumes. Correspondingly the complete N management of these rota-tional systems has to be organised through... |

| A survey about common practice in organic vegetable production was carried out on 100 farms in 2002 and 2003 that ranged from small to big scale vegetable holdings and reflected all important growing regions in Germany. Aspects of structure and production techniques were considered. Evaluations were made by categorizing (a) into three regional groups – South (Bavaria and Baden-Württemberg) |S|, East (New Länder) |E| and North/West (other Old Länder) |NW| - (b) into seven groups of producer organisations and (c) into eight groups of cultivation area for vegetables. The visited farms were either pure market gardens or farms with agricultural and horticultural crops or farms with or without production in greenhouses. Farms with more UAA were located in |E|... |

| Organic agriculture can and should play an important role in solving future challenges in producing food. The low level of external inputs combined with knowledge on sustainablity minimizes environmental contamination and can help to produce more food for more people without negatively impacting our environment. Organic agriculture not only includes farming as a production practice but it also includes processing, trade and consumption. Nevertheless, Organic agriculture must always evolve to overcome emerging challenges. Science-based knowledge attained through dedicated research is required to strengthen organic food and farming as a means to solve future challenges. In 2010, a global discussion about Organic 3.0 was initiated to address current problems... |
