10 Jahre differenzierte Grundbodenbearbeitung im Ökologischen Landbau. Auswirkungen auf die Besiedlung mit Collembolen Organic Eprints
Bassemir, Ursula K..
During 10 years a crop rotation schedule consisting of different crops (green fallow; intercrop: winter wheat; peas; intercrop: winter rye; summer barley) was combined with three different tillage techniques (plough, inverting to 30 cm depth, intensive; two-layer plough, inverting to 15 cm depth and loosening to 30 cm depth, reduced inverting; layer cultivator, loosening to 30 cm depth, conservation tillage). First results show a significant effect of crop on springtails. There is no significant effect of tillage techniques, although there is a tendency in slightly increased population density of springtails by using plough and layer cultivator. Further detailed results will be reported elsewhere.

100% local and organic: closing the protein gap for poultry in the ICOPP Project Organic Eprints
Nelder, Rebecca; Smith, Jo; Clements, Ruth; Pearce, Bruce.
A key challenge in improving the sustainability of organic poultry production is meeting the required levels of nutrients from locally sourced organic feeds. 100% organic diets for monogastrics will become compulsory in the EU from 1st January 2015. The ICOPP project brings together knowledge, from 10 EU countries, of local feeds for monogastrics and their wider impact on growth, health and welfare and the environment to identify feeding strategies which comply with organic principles. This poster will report on feeding trials carried out with broilers in the UK by FAI and ORC to investigate the impact of algae, peas and lupins on broiler performance and welfare.

100% Organic Feed for Pigs – Results of Feed Trials in the UK Organic Eprints
Smith, Jo; Gerrard, Catherine L.; Nelder, Rebecca; Clements, Ruth; Pearce, Bruce; Zaralis, Konstantinos.
Current regulations for organic pig and poultry production systems permit feed ingredients of non-organic origin, primarily due to concerns that a 100 % organic diet would be unable to meet the demand for the essential amino acids lysine and methionine. 100 % organic diets for monogastrics will become compulsory in the EU from 1st January 2015, and so there is an urgent need to develop economically profitable feeding strategies based on organic feed across Europe. Feeding trials carried out with Gloucester old spot pigs in the UK found that there was no significant difference in the weight gains across the diets until the last week of the trial when there a significant difference in weight increase for the male pigs on the bean diet. This suggests that a...

100% Organic Feed for Poultry – Results of Feed Trials in the UK Organic Eprints
Gerrard, Catherine L.; Smith, Jo; Nelder, Rebecca; Clements, Ruth; Pearce, Bruce; Bright, Ashleigh.
Current regulations for organic monogastric production systems permit feed ingredients of non-organic origin, primarily due to concerns about meeting the demand for the essential amino acids methionine and lysine. However, 100 % organic diets will become compulsory in the EU from 1st January 2015, so there is a need to develop feeds which will supply the required level of nutrients and support high animal health and welfare. This paper reports on feeding trials carried out with broilers in the UK to investigate the impact of three 100 % organic diets: a control diet with globally sourced ingredients, a diet based on locally sourced (i.e. within Europe) organic ingredients, and a diet based on locally sourced organic ingredients and algae. The results of...

100%-Biofütterung mit Rapskuchen und heimischen Körnerleguminosen bei der Fütterung von Legehennen verschiedener Herkünfte Organic Eprints
Rahmann, Gerold; Holle, Romana; Andresen, B; Andresen, C.J..
Rations of 100% organic and local origin were tested. Up to 18% of thermally proc-essed rape cake was fed in different rations to two groups of laying hens. Faba beans, Vicia sativa and blue lupines were used as protein supplements to create a feeding ration. High vicine and covicine contents, especially in Vicia sativa, led to a refusal of some food rations. No ration has been found suitable for daily use. Chicken fed with a rape cake ration laid eggs with a positive fatty acid pattern, which is favourable for human diets.

10-year interdisciplinary monitoring of organic stocklass, vegetable rotations at Warwick-HRI, Kirton, South Lincolnshire, UK Organic Eprints
Schmutz, U; Rayns, F; Sumpton, P.
Interdisciplinary monitoring of an organic stockless farming system has been carried out over ten years on a fertile silty clay loam in the main vegetable production area of the UK. The results draw together economic outcomes with agronomy, soil science and agro-ecology. Organic management has been used at the Kirton research site since conversion of a 3.2 ha unit in 1997. There is great variability in crop yields and marketing results but overall a successful ongoing vegetable production system has been established. Soil fertility, weeds, pests and diseases have been managed successfully without imports of animal manures or green waste compost. Production costs are well controlled and marketable yields are good. However, because the site is a research...

15 years of research in organic food systems in Denmark – effects on the sector and society Organic Eprints
Rasmussen, Ilse A.; Halberg, Niels.
The Danish government has funded research in organic agriculture and food systematically since the establishment in 1996 of the Danish Research Centre for Organic Farming (DARCOF, now ICROFS, International Centre for Research in Organic Food Systems). A recent analysis of the effects of the first 3 organic research programs (DARCOF I-III, 1996-2000) (Halberg et al. 2012) was carried out with the objective to determine not only the impact of the research on the sector from farmers and advisors to industry and retail but also on society from government and regulation to NGO’s.

15 years of research in organic food systems in Denmark – effects on the sector and society Organic Eprints
Rasmussen, I.A.; Halberg, N..
An analysis of the effect of 15 years of research in organic food systems in Denmark showed that it has had a high impact on the development of the sector. There are three main reasons: First of all, the content of research programs and the funded projects have been closely aligned with the needs of the industry as expressed by farmers, advisors and organizations. Second, many of the projects have had close contact to advisors and farmers securing continuous dissemination resulting in rapid application of results. Third, due to the close contact between researchers and users the research design has been adapted to ensure that treatments to be tested are as relevant and practical as possible, without compromising the scientific standards. Besides the...

15Nitrogen transfer from legumes to neighbouring plants in multi-species grassland Organic Eprints
Pirhofer-Walzl, K.; Høgh-Jensen, H.; Rasmussen, J.; Rasmussen, J.; Søegaard, K.; Eriksen, J..
This study investigates the N transfer from legumes to neighbouring plants, grasses, legumes and herbs in a temperate grassland. In a field experiment white clover (Trifolium repens), red clover (Trifolium pratense) and lucerne (Medicago sativa) were leaf-labelled with 15N enriched urea. The 15N tracer was measured in above-ground plant tissue of eight neighbouring plants in two subsequent harvests in 2008. The three legumes donated 15N to all neighbouring plants, of which grasses, white and red clover were strong receivers. Results show that N transfer increases with N application and from the 1st to the 2nd cut.

15Nitrogen uptake from shallow- versus deep-rooted plants in multi-species mixtures and monoculture grassland Organic Eprints
Pirhofer-Walzl, K.; Høgh-Jensen, H.; Rasmussen, J.; Rasmussen, J.; Søegaard, K.; Eriksen, J..
Only few studies have explored the importance of functional diversity in temperate agricultural grasslands in relation to nitrogen (N) uptake. This study investigates the consequence of growing deep-rooted plants together with grass-clover mixtures in terms of N uptake efficiency from deep soil layers. The objective was to compare the N uptake of the shallow-rooted grassland species Lolium perenne and Trifolium repens; and the deep-rooted species Cichorium intybus and Medicago sativa in monocultures and mixtures. We hypothesized that growing deep-rooted plant species in mixture with shallow-rooted species increases the N uptake from deep soil layers partly through competition. A 15N tracer study was carried out with 15N enriched ammonium-sulphate placed at...

20 Jahre ‚Gäa e.V. - Vereinigung ökologischer Landbau’ Organic Eprints
Wolf, Dipl.-Ing. agr. D.; Hirte, Dr. K.; Schüler, Dr. C.; Heß, Prof. Dr. J..
For the understanding of ecological agriculture, knowledge of its roots is essential. Actual literature about this topic does not cover the history of ecological agriculture in East Germany especially if chronological development and individual motivation are seen as mutual dependent. The ecological organisation Gäa e.V. was founded in the GDR in 1989. Its origins were oppositional environmental groups working within the East German church. It developed own principles based on individual experience with unique aspects. It has established and integrated well in the German ecological agriculture structure after the reunification and the changed political background as an authentic representative of and for the East German ecological agriculture scene.

20 Jahre Modellbetrieb für Ökolandbau in Müncheberg. Teil 1: Entwicklung von Humus- und Nährstoffgehalten Organic Eprints
Bachinger, Johann; Bloch, Ralf; Reckling, Moritz; Stein-Bachinger, Karin.
Acht Felder der Versuchsstation des ZALF in Müncheberg in Nordostdeutschland wurden 1993 als Modellbetrieb mit einer Leguminosen-betonten Fruchtfolge auf Ökologischen Landbau umgestellt. Je Feld wurde 1995 ein Monitoringversuch mit je 5 Ernte- bzw. Beprobungsparzellen angelegt. Neben Ernteerhebungen erfolgte eine jährliche Krumenbeprobung zur Untersuchung der Entwicklung der Gehalte an organischem Kohlenstoff (Corg) und Stickstoff (Norg) sowie der P- und K-Verfügbarkeit. Eine deutliche Zunahme der Corg-Gehalte zeigte sich nur auf den Flächen mit Texturklasse Sand. Dagegen stiegen die Norg-Gehalte auch auf den besseren Böden, allerdings in geringerem Maße, an. Die P-Verfügbarkeit pegelte sich nach einem anfänglichen Rückgang auf Werte der Versorgungsstufe...

20 Jahre Modellbetrieb für Ökolandbau in Müncheberg. Teil 2: Wie ertragslabil sind Körnerleguminosen im Vergleich zu Getreide und Mais? Organic Eprints
Reckling, Moritz; Döring, Thomas F.; Bloch, Ralf; Stein-Bachinger, Karin; Bachinger, Johann.
Auf dem Modellbetrieb für Ökolandbau in Müncheberg wurden von 1993 bis 2013 Feldversuche zur Ermittlung der Ertragsstabilität von zwei Körnerleguminosen (Schmalblättrige Lupine und Futtererbse), Wintergetreide (Roggen und Weizen), Hafer und Silomais durchgeführt. Zwei orthogonale Datensätze wurden genutzt um die temporären Ertragsschwankungen der Einzelkulturen zu vergleichen. Beide Körnerleguminosen zeigten die geringste Ertragsstabilität von allen untersuchten Kulturen. Dies war sowohl für varianzbasierte als auch für regressionsbasierte Stabilitätsparameter der Fall. Gründe für die geringe Ertragsstabilität sind unzureichend bekannt. Es müssen Strategien für das Management entwickelt werden, um mit den großen Schwankungen umzugehen.

2011 Approaches for organic food and feed authentication Organic Eprints
van Ruth, S.M.; Alewijn, M.; Tres, A.; van der Veer, G..
People’s growing awareness of health, environment and animal welfare has led to an increased public interest in the quality of foods and food production systems. This in turn boosted organic production. Due to higher production costs, organic produce tends to retail at a higher price than their conventional counterparts. As a consequence of the premium price, organic produce is susceptible to fraud. Fair competition between producers and sustained consumer confidence favour organic production, and it requires regular confirmatory assessments of the identity of organic produce in addition to administrative controls. Traditional analytical strategies for guaranteeing quality and uncovering adulteration have relied on the determination of the amount of a...
