| Die Zielsetzung des Forschungsprojektes war es, verschiedene Mischfruchtanbausysteme von Getreide oder Leguminosen mit Ölsaaten zu untersuchen. Es wurden zweijährige Parzellenversuche mit ökologischer Bewirtschaftung an vier Standorten in Deutschland durchgeführt. Bei den Sommersaaten wurden Gemenge aus halbblattlosen Erbsen (Pisum sativum L.) mit Leindotter (Camelina sativa L. Crantz), weißem Senf (Sinapis alba L.) oder Sommerraps (Brassica napus L.), Gemenge aus schmalblättriger (blauer) Lupine (Lupinus angustifolius L.) mit Leindotter oder Saflor (Carthamus tinctorius L.), Gemenge aus Sommerweizen (Triticum aestivum L.) mit Öllein (Linum ustitatissivum L.) oder Leindotter sowie Gemenge aus Öllein mit Leindotter untersucht. Bei den Winterungen wurden... |

| Grazing provides livestock better opportunities to act out their species specific behaviour compared to the restrictive stable conditions. Studies on the effect of grazing on animal welfare in dairy farming in Germany are rare and have not been conducted under the specific conditions of organic dairy farming. The aim of the present study was to examine the effects of grazing on animal welfare of dairy cows in organic and conventional farming based on the Welfare Quality® protocol for dairy cattle. In this paper, we present the initial evaluation of a comparison between zero grazing and summer grazing. The first results indicate an improvement in most welfare principles during the summer months for dairy cows with summer grazing, except for between... |

| While grain legumes can be regarded as highly valuable protein source for animal nutrition, certain drawbacks inhibit their use as sole foodstuff for livestock. The nutrient quality is reduced by low concentrations of tryptophan and sulfur amino acids. In the past substantial breeding effort has been invested in the reduction of antinutritional components and disease resistance while the protein quality has not been a focal point. To improve the protein quality the elevation of the low sulfur amino acid content is of prominent importance especially for organic production where high methionine feed components are rare. The present work tries to establish a method to select methionine enriched grain legumes for further breeding steps. Agronomical important... |

| In Versuchen zum ökologischen Mischfruchtanbau von Lein mit Sommerweizen (Triticum aestivum L.), Hafer (Avena sativa L.) oder Leindotter (Camelina sativa L.) wurden die Leinerträge stets deutlich gegenüber den Reinsaatvarianten reduziert. In Sommerweizen waren Leinsamenerträge zwischen 0,1 bis 3,7 dt ha-1 und in Mischung mit Leindotter zwischen 0,7 und 10 dt ha-1 (Trockensubstanz) möglich. In beiden Kulturen konnte der Anteil an Leinsamen im Erntegut durch Absenken der Saatmenge des Mischungspartners erhöht werden. Eine möglichst gleichmäßige Verteilung der Leinsaat als Drillsaat über die Fläche lieferte die höchsten Leinerträge im Mischfruchtanbau. Die Erträge von Sommerweizen oder Leindotter im Mischfruchtanbau waren überproportional hoch verglichen mit... |

| Local oil mills, processing organic oilseeds solely, suffer competitive disad¬vantages by lower workloads due to low organic yields. Organic rapeseed oil as sub¬stitute for diesel fuel is not economically justifiable due to its high production costs and opportu-nity costs in the food market. Only organic sunflower oil or oil of false flax (Camelina sativa) grown in mixed cropping systems have produc¬tion costs comparable to con-ventional rapeseed oil. An ecobalance showed that false flax oil from mixed cropping systems as substitute for diesel has clear ecological advantages compared to oil from single cropped oilseeds. But the use of false flax as fuel in engines is still not proofed in science and technology. |

| Mixed cropping systems with oil crops are of growing interest in organic farming. They can offer agricultural advances like competition against weeds, support against lodg¬ing and buffering of yield fluctuations. The aim of the cultivation method is to gain additional oil yields for energy or feed purposes. The reported higher land-efficiency-ratios of those mixed cropping systems should lead to higher nutrient requirements. But it is unknown if the different crops just compete for rare soil nutrients or if comple¬mentary effects in mixed cropping systems lead to higher nutrient efficiency. In a field study N-contents in plants and N uptake of diverse mixed cropping systems were compared to sole cropping systems. In linseed (Linum usitatissivum) or false... |

| Although the crop rotation is an essential element of organic farming, only few long-term trials exist which compare different crop rotations under temperate climate. The long-term monitoring Trenthorst was established in 2003 and comprises the different crop rotations of two cash crop farms and three livestock farms specialised in dairy, pigs and goats/oil seeds respectively. In addition to the comparison of crop rotations under practical farm conditions the long-term monitoring study aims to analyse the development of soil parameters, yields and crop qualities after the conversion to organic agriculture. On each arable field four monitoring points were established, where the relevant parameters are measured. The yields of the first three years are... |

| For reasons of animal health, milk yield and for environmental issues an optimal supply of protein and energy for dairy cows is essential. The aim of this study is to examine potential protein and energy malnutrition and surplus in dairy herds. We present a comparison of the protein and energy supply between 18 conventional and 16 organic dairy herds. Initial results indicate an undersupply on energy in the first one hundred days of lactation in both the organic and conventional feeding regimes. It is easier to provide an adequate protein supply in conventional conditions in the first one hundred days than in organic ones. A balanced supply is guaranteed for a mere 21,3 % of the organic cows. In the second one hundred days this increases to 26,5 %,... |

| Four organic dairy farms of a German farm network (www.pilotbetriebe.de) were described in detail with respect to average diets and feedstuff quality, and were compared to the mean results of the 22 organic and 22 conventional farms of the network. At milk yields between 4,469 and 6,769 kg energy corrected milk (ECM) a-1, rations of three farms almost completely depended on grass and grass clover from both grassland and arable land (96-100 %; mean organic approx. 75 %). The fourth farm was similar to the average conventional milk yield and diet (incl. maize silage and a high share of concentrates) hence it largely depended on arable land. Enteric methane (CH4) emissions per kg ECM were higher the more fibre rich feedstuffs were fed and, as expected, the... |

| In Deutschland ist die Milchviehhaltung für 30 % der gesamten Treibhausgasemissionen der Landwirtschaft verantwortlich. Zu den größten Verursacherbereichen der landwirtschaftlichen Emissionen in Deutschland gehören die landwirtschaftlichen Böden, die mineralische Düngung, die Emissionen aus der Fermentation aus der Verdauung der Tiere und die Lagerung und Anwendung von Wirtschaftsdüngern. Auf der anderen Seite steigert ein gezielter Einsatz von Wirtschaftsdüngern die Erträge und mindert die Notwendigkeit von Mineraldüngern, was zu einer Senkung der Treibhausgasbelastungen führen kann. Trotz der Bedeutung zu Klimawirkungen der Landwirtschaft, gibt es in der Literatur kaum aussagekräftige Datensätze von Wirtschaftsdüngern in Bezug auf Menge und Qualität und... |

| Mineral phosphorus (P) fertilizers from fossil reserves are finite which puts agriculture at risk of losing soil fertility. This study calculates P soil balances of an organic dairy farm in Northern Germany to focus on potentials and variations in the farm P cycle. P flows were different between the years because yield levels and amount of manure application varied. Different plant species showed different P export which depended mainly on biomass export. This can also be seen as their site specific mobilization potential. The highest mean P export between 2010 and 2012 was measured with maize (mean 30.4, range 17.7-38.2 kg P ha-1 a-1) and grass-clover (mean 23.7, range 17.3-29.5 kg P ha-1 a-1). By grazing, permanent grassland showed a mean P mobilization... |

| Eine Reihe von Untersuchungen zeigen, dass die Fruchtfolgegestaltung, die Bodenbearbeitung, die Sortenwahl sowie Pflanzenschutzmaßnahmen maßgeblichen Einfluss auf den Fusariumbefall von Kulturpflanzen haben. Als Folge von Fusariuminfektionen kann es insbesondere bei Getreide zu unerwünschten Kontaminationen mit Fusarientoxinen, wie z.B. dem Deoxynivalenol (DON), kommen. In den Jahren 2003 – 2005 wurden in den 3 Fruchtfolgen des ökologisch bewirtschafteten Versuchsbetriebes Trenthorst (Institut für Ökologischen Landbau, vTI) die Kulturarten Weizen, Triticale, Hafer, Gerste, Dinkel, Ackerbohnen, Erbsen, Blaue Lupinen, Raps, Öllein, Leindotter, die z.T. auch im Gemenge angebaut wurden, auf den DON-Gehalt untersucht. Parallel wurden von 4 benachbarten,... |

| Auf die in den 50er und 60er Jahren publizierten Theorien zur Bodenfruchtbarkeit von Hans Peter Rusch wird im organisch-biologischen Landbau heute noch Bezug genommen. Zu nennen sind hier der Rusch-Test zur Einstufung der biologischen Qualität der organischen Substanz und von Böden, die Systematisierung des Abbaus organischer Substanz im Boden und der Humusbildung sowie die Flächenkompostierung. Ruschs Lehren zielen auf eine Verbesserung der Bodengare durch effiziente Zufuhr organischer Substanz und Humusbildung sowie auf die Verbesserung der Ausnutzung von Nährstoffen. Gegen den Geist seiner Zeit grenzte sich Rusch von der Mineraldüngung ab und hebt die auch heute unbestrittene Rolle des Humus für die Bodenfruchtbarkeit hervor. Die tatsächliche Bedeutung... |
