| Collembolans, a widespread group of soil fauna, could potentially be used as indicators of management changes in (organic) farming systems. Therefore, we studied effects of reduced tillage compared with conventional tillage on collembolan communities in the short term. Results of a two-year field trial showed that collembolan communities are likely influenced by different tillage systems. However, these effects could not be statistically verified. Furthermore, annual variation seems to strongly influence the composition of collembolan communities. We tend to assign these effects to different crops cultivated during our study. |

| 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. |

| Manure samples from 194 farms with organic livestock production were analysed for their macro- and micronutrient contents. Guidance values for N, P, K, Mg and S concen¬trations given for conventional systems are within the range of values ¬determined here for organic farms. However, they can only be used for first estimations in fertilization planning, since – as demonstrated by the presented data – nutrient contents may vary over a wide range. This was also the case for the micronutrient concentrations (B, Cu, Zn, Mn, Mo and Se). Fertilization with 1t/ha dry matter of ma¬nure with higher micronutrient concentrations can cover the demand of organically produced crops in nutrient balances. Micronutrients applied with fertilizers or in feed additives are... |

| 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... |

| While grain legumes can be regarded as highly valuable protein sources for animal nutrition, ceratin drawbacks inhibit their use as sole foodstuff for livestock. The nutrient quality is reduced by low concentrations of tryptophan and sulfur amino acids. |

| Organic and conventional feeding practices of dairy cattle differ due to specific regulations that are in place for organic farming. E.g., dairy cows must have access to pasture, and soybean extract, a very common concentrate in conventional dairy feeding, may not be fed. The joint project “Climate Effects and Sustainability of Agricultural Systems – Analyses in a Network of Pilot Farms” determined feeding practices and feed qualities on a total of 44 dairy farms (22 organic and conventional, each) in four German regions for 2008, 2009 and 2010. The average diets of the dairy cows differed considerably between organic and conventional dairy farms. Organic farms with a high percentage of hay in the diet were found in East and South Germany. The low... |

| 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... |

| The long-term monitoring Trenthorst, situated near Lübeck in a temperate maritime climate on loamy soils, was established in 2003 and compares two cash crop and three livestock farming systems. We studied the soil mineral nitrogen contents of one cash crop and two livestock farms, specialised in dairy cows and goats/oilseeds resp., with the hypothesis that the livestock farms show a more even course of Nmin in the rotation and a higher rotation mean. The rotation average of Nmin in the cash crop farm was not lower than the ones in the livestock farms. But in the course of the rotations differences became evident: compared to the livestock farms the cash crop farm showed higher Nmin-values after the first rotation year (mulched vs. cut grass clover) but... |

| 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... |

| Die bedarfsgerechte Versorgung von Monogastriern mit den essentiellen und limitierenden Aminosäuren ist von großer Bedeutung. Im Ökologischen Landbau wirft dies aufgrund von unbefriedigenden Aminosäureprofilen der zur Verfügung stehenden Getreide- und Körnerleguminosenarten sowie der fehlenden Verfügbarkeit alternativer Einzel- und Ergänzungsfuttermittel Probleme auf. Durch die Differenz zwischen Aminosäurebedarf und –versorgung entsteht die sog. Aminosäurelücke. Um diese zu füllen, ist es nach EU Öko-Verordnung (EG 834/2007, EG 889/2008 und EU 505/2012) gestattet, die Ration für monogastrische Nutztiere aufzuwerten, indem 5 % der landwirtschaftlich erzeugten Proteinfuttermittel konventioneller Herkunft sein dürfen. Diese Ausnahmegenehmigung läuft zum Ende... |

| 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... |

| Im ökologischen Landbau ist der Anbau von Raps aufgrund des Schädlingsbefalls mit einem hohen Risiko behaftet (Petterson et. al. 2002; Haas u. Kramer, 1995). Weiterhin stellt Raps als stark stickstoff- (N) -zehrende Kultur hohe Ansprüche an die Vorfrucht und an die organische Düngung (Gruber, 2001; Mayer et. al., 2001; Loges u. Böhm, 2001). Er konkurriert aus diesem Grund im ökologischen Landbau mit Weizen um den Platz in der Fruchtfolge. Für die N-Versorgung der Nachfrucht erscheint es daher günstig, im Raps eine Kleeuntersaat zu etablieren. Es wurden verschiedene Verfahren des Rapsanbaus erprobt. Eine Weisskleeuntersaat zwischen den Reihen trug im ersten Versuchsjahr weder meßbar zu einer Verbesserung der N-Versorgung von Winterraps bei, noch konnte... |

| 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 %,... |
