| Voraussetzungen für einen erfolgreichen Anbau von Verarbeitungskartoffeln sind außer einem hohen Ertrag vor allem die von der Kartoffel verarbeitenden Industrie geforderten produktspezifischen Qualitäten für Pommes frites und Chips. Für die Verarbeitung zu Pommes frites muss z.B. ein hoher Anteil großfallender Knollen realisiert werden oder bei Chipskartoffeln bestehen strenge Vorgaben für die Gehalte an reduzierenden Zuckern. Um hohe Zuckergehalte zu vermeiden, erfolgt die Kartoffellagerung bei 8°C, was erhöhte Ansprüche an die Lagerfähigkeit bedeutet. In dem gemeinsam von der Universität Kassel (FG Ökologischer Land- und Pflanzenbau, Projektleitung), der FAL (Institut für ökologischen Landbau), der Universität Kiel (Institut für Pflanzenbau und... |

| To follow the responsibility to preserve the creation, both the Protestant and the Catholic Church committed to the principle of sustainability. This also leads to a raising interest in both organic farming on agricultural property of the Church and organic food in church institutions. The first aim of the study was to get an overview of the current state of organic farming in both churches by means of a literature review. The second aim was to get insights into experience, obstacles and achievements of the churches regarding organic farming. This also included information on successful cooperation and future developments in this area. To achieve this second goal, expert interviews were conducted. |

| The effect of ploughing depth and mechanical soil loading on the performance of pea sole crops, oat sole crops and pea–oat intercrops was investigated in field experiments under organic farming conditions at two sites in Germany in 2009 and 2010. The two ploughing depths were short-term shallow ploughing to a soil depth of 7–10 cm and deep ploughing to 25–30 cm. Wheel loads of 26 and 45 kN, which correspond to typical rear wheel loads of field machinery used during sowing operations, were compared to an uncompacted control. Shallow ploughing resulted in a greater penetration resistance in the 14–28 cm soil layer compared to deep ploughing. An increase in mechanical soil loading intensity increased the bulk density and decreased the air capacity in the... |

| Winter peas have several agronomic advantages in comparison to spring pea, but the overwintering of winter peas are uncertain under the climatic conditions in Germany. Therefore, the winterhardiness of four genotypes (cvs. Assas, Cheyenne, EFB 33, Württembergische) was examined in two field trials in three growing seasons. In a first trial all peas were grown in pure and mixed stands with rye at the experimental farm of the University of Kassel and at the experimental farm of the University of Applied Sci-ence in Osnabrueck. In a second trial the impact of three sowing dates (mid of Sep-tember, end of September/begin of October and mid of October, respectively) was de-termined at the experimental farm of the University of Kassel only in pure stands. In... |

| In einer schriftlichen Umfrage wurden alle (1373) Luxemburger Landwirte, welche mehr als 5 ha Ackerland haben, zu ihrer Meinung zum Anbau von Körnerleguminosen als regionales Futtermittel befragt. Der Rücklauf war mit 29 % sehr hoch. 83 % der Landwirte bauen keine Körnerleguminosen an. Hauptgrund sind mangelnde Kenntnis und Information über diese Kulturen. 67 Betriebe bauen Körnerleguminosen an. 85.2 % der teilnehmenden Bio-Betriebe bauen Körnerleguminosen an und nur 11.8 % der teilnehmenden konventionellen Betriebe. Positive (z.B. Bodenfruchtbarkeit, Einsparung von Dünger und Erweiterung der Fruchtfolge)und negative (schwankende Ertragsleistungen, Probleme bei der Ernte und bei der Unkrautbekämpfung) Erfahrungen mit dem Körnerleguminosen-Anbau sind die... |

| The Aim of this study has been to evaluate in two two-year field trials the pre-crop effect of different grain legumes (e.g. soy bean, peas or lupines) in the same environment and to detect possible effects of grain legumes on the N-supply, the yield potential and the yield structure of the subsequent crop winter wheat. According to different pre-crop yields, a higher but different nitrogen supply for subsequent winter wheat was observed in all N2-fixing pre-crop treatments. In contrast to non-fixings control higher NO3-N contents in soil and higher yields in subsequent winter wheat (up to 24 dt*ha- 1 surplus) were observed. |

| Stoffeinträge aus der Landwirtschaft in das Grund- und Oberflächenwasser stellen ein hohes Umweltrisiko dar. In einer systematischen Literaturübersicht wurden ökologische und konventionelle Landwirtschaft hinsichtlich der jeweiligen Belastungen des Grund- und Oberflächenwassers im Vergleich untersucht. Insgesamt wurden 96 Vergleichsstudien mit 308 Vergleichpaaren evaluiert. 63% der Vergleichpaare zeigen Vorteile des ökologischen Landbaus in Bezug auf Nitratausträge, genauso 90% der Vergleichspaare in Bezug auf Pestizidbelastungen. Im Schnitt (Median) können unter ökologischer Bewirtsvchaftung 28% weniger Nitratauswaschungen festgestellt werden als in der konventionellen Landwirtschaft, zudem werden keine Pestizide und vermutlich auch weniger... |

| Conservation agriculture and organic farming are considered as promising sustainable agricultural system for producing food, while minimizing environmental impacts. Despite an increasing number of experimental data on organic conservation practices and various studies dealing with the adoption of conservation agriculture by farmers, none of those studies have specifically addressed conservation agriculture adoption under organic conditions in Europe. We carried out a survey with 159 farmers located in 10 European countries. These farmers had applied at least two of the following conservation practices: (i) no-tillage, (ii) reduced tillage and (iii) green manures. Each farmer assessed socio-economic, agronomic and environmental motivations and problems for... |

| Der Einsatz moderner Pferde gezogener Geräte stellt eine nachhaltige Alternative zum Schleppereinsatz dar, besonders im Ökologischen Landbau. Feldversuche zu den Leistungsdaten eines Vorderwagens in Kombination mit drei verschiedenen Doppelmesser-Mähwerken (Arbeitsbreiten 1,65 m, 1,90 m, 2,40 m) wurden durchgeführt. Bodenantrieb im Vergleich zum Motorantrieb der Zapfwelle führte zu einem mehr als doppelt so hohen Zugkraftbedarf und überstieg die Dauerzugleistungfähigkeit der 850 kg schweren Arbeitspferde. Die Arbeitsgeschwindigkeit war für alle Pferde gezogenen Variante in etwa gleich (ca. 4,9 km/h), die Flächenleistung nahm mit steigender Arbeitsbreite von 0,69 ha/h (1,65 m) über 0,78 ha/h (1,90 m) auf 1,00 ha/h (2,40 m) zu. Das 2,40 m-Mähwerk war das... |

| The evaluation of research beyond scientific impact is increasingly required, but has not yet been widely applied. One reason is that data necessary for the evaluation of the societal impact of science are often not available in sufficient quantities or suitable form. This paper describes first results from a research project that develops improved documentation to serve evaluation beyond scientific impact. Firstly, we refer to the need to do this, and to the specific challenges for data assessment in this area. Secondly, we describe the concept for documenting achievements of research beyond scientific impact with a research information system that integrates the relevant parts of research proposals and reports. This enables data to be provided without... |

| The nitrogen supply can be a yield-limiting factor in organic farming, especially when reduced tillage is applied. An organic field experiment was conducted from 2007 to 2013 to analyse the potential of the nitrogen supply through the efficient use of green manure crops in different tillage systems. Three farming systems were compared: a stubble cleaner system (SC) and a plough system (PL), both in a cereal-based crop rotation, and another plough system in a crop rotation that included alfalfa grass ley (PLALF). In the fifth year of the experiment, the experimental design was extended into a split plot design, and seven green manure treatments (Lolium perenne, Phacelia tanacetifolia, Sinapis alba, a mixture of Sinapis alba and Trifolium resupinatum,... |

| The Hessian state domain Frankenhausen near Kassel was converted to organic farming in July 1998 and serves as a research and demonstration farm of the univer-sity. Before that time the farm changed constantly by typical intensification of conven-tional farming: The landscape is a mirror of intense use: cleared and drained fields, canalised brooks and large fields with few structural elements. – Within the project “The Integration of Nature Conservation into Organic Farming” (supported by the German Federal Agency for Nature Conservation with funds from the Federal Envi-ronmental Ministry) and based on the analysis of the present situation using methods of landscape ecology. Measures to restore brooks, structural elements and biotopes are to be... |

| Das Ziel des Beitrags ist die Bestimmung der N-Aufnahme unterschiedlicher legumer und nicht-legumer Gründüngungsarten sowie deren Wirkung auf die N-Verfügbarkeit zur Hauptfrucht Hafer, der in verschiedenen Bodenbearbeitungssystemen nach der Gründüngung angebaut wurde. Besonders hohe und von den anderen Gründüngungsarten signifikant verschiedene N-Werte fanden sich im Aufwuchs von Vicia sativa. V. sativa war auch die Gründüngungsart, die zu den höchsten Nmin-Werten im Frühjahr in allen Bodenbearbeitungssystemen führte. Auch die Bodenbearbeitung hatte einen Effekt auf die N-Verfügbarkeit: nach Pflügen war sie tendenziell höher als nach Bearbeitung mit dem Grubber und signifikant höher als nach Mulch- bzw. Direktsaat. |

| The nitrogen supply plays an important role in achieving quality characteristics in organic potato farming. Different defoliation systems of ryegrass–clover may influence the amount of fixed nitrogen available to the tubers. In a field experiment, the effect of different defoliation systems (cutting, mulching and a combination of them) of the pre-crop ryegrass–clover on selected quality attributes of organically grown potatoes, destined for processing into French fries (cv. Agria) or crisps (cv. Marlen), were conducted in two consecutive years (2003 and 2004). Parameters studied included compounds related to the sensory properties of potato food (tuber dry matter, starch, reducing sugars) as well as nutritional quality (nitrogen,minerals). Selected... |
