Neues Biomittel schaltet Kirschenfliege weitgehend aus Organic Eprints
Daniel, Claudia.
Die Kirschenfliege trat in den letzten Jahren verstärkt auf und verursachte hohe Ertragsausfälle. Ab 2009 ist nun das Mittel «Naturalis-L» zur Bekämpfung zugelassen. In Versuchen wurde ein Wirkungsgrad von 70 Prozent erreicht. Das sieht nach einem Durchbruch für den Biokirschenanbau aus. Für den erfolgreichen Einsatz gilt es jedoch einige Stolpersteine zu umgehen.

Diversity of mitochondrial large subunit rDNA haplotypes of Glomus intraradices in two agricultural field experiments and two semi-natural grasslands Organic Eprints
Börstler , Boris; Thiéry, Odile; Sýkorová, Zuzana; Berner, Alfred; Redecker, Dirk.
Glomus intraradices, an arbuscular mycorrhizal fungus (AMF), is frequently found in a surprisingly wide range of ecosystems all over the world. It is used as model organism for AMF and its genome is being sequenced. Despite the ecological importance of AMF, little has been known about their population structure, because no adequate molecular markers have been available. In the present study we analyse for the first time the intraspecific genetic structure of an AMF directly from colonized roots in the field. A recently developed PCR-RFLP approach for the mitochondrial rRNA large subunit gene (mtLSU) of these obligate symbionts was used and complemented by sequencing and primers specific for a particularly frequent mtLSU haplotype. We analysed root samples...

Antiparasitic activity of chicory (Cichorium intybus) and its natural bioactive compounds in livestock: a review Organic Eprints
Peña-Espinoza, Miguel; Valente, Angela H.; Thamsborg, Stig M.; Simonsen, Henrik T.; Boas, Ulrik; Enemark, Heidi L.; López-Muñoz, Rodrigo; Williams, Andrew R..
Increasing drug resistance in gastrointestinal (GI) parasites of livestock and concerns about chemical residues in animal products and the environment are driving the development of alternative control strategies that are less reliant on the use of synthetic drugs. An increasingly investigated approach is the use of bioactive forages with antiparasitic properties as part of the animal’s diet (nutraceuticals) or as potential sources of novel, natural parasiticides. Chicory (Cichorium intybus) is a multi-purpose crop and one of the most promising bioactive forages in temperate regions, and numerous in vivo trials have explored its potential against parasitic nematodes in livestock. However, it is unclear whether chicory can induce a direct and broad activity...

In vitro compatibility of microbial agents for simultaneous application to control strawberry powdery mildew (Podosphaera aphanis) Organic Eprints
Sylla, Justine; Alsanius, Beatrix W.; Krüger, Erika; Becker, Dorit; Wohanka, Walter.
Biological control of plant pathogens on strawberries may be improved by the simultaneous application of different biological control agents (BCAs). Therefore, the compatibility of various BCAs which had previously shown to be effective against powdery mildew (Podosphaera aphanis (Wallr.) U. Braun & S. Takam) under laboratory conditions was examined in vitro. Inhibitory effects between fungal and bacterial BCAs were demonstrated in dual culture tests on two solid nutrient media. Leaf disc assays with single and multiple strain treatments demonstrated either unaffected or significantly improved control of P. aphanis for many multiple strain treatments, even if antagonistic interactions previously occurred in dual culture tests. Highest inhibition of...

Die Öko-Zertifizierung in Deutschland aus Sicht der Produzenten: Handlungsvorschläge zur politischen Weiterentwicklung Organic Eprints
Schulze, Holger; Jahn, Gabriele; Neuendorff, Jochen; Spiller, Achim.
Um den veränderten Anforderungen des ökologischen Marktes gerecht zu werden (z.B. zunehmende Internationalisierung) hat sich der Agrarrat im letzen Jahr (28. Juni 2007) auf eine neue Verordnung zur Produktion und Kennzeichnung von ökologischen Produkten verständigt (VO (EG) Nr. 834/2007). Die Öko-Kontrolle soll zukünftig europaweit durch staatliche Behörden durchgeführt werden, die nur „genau beschriebene Aufgaben“ an private Öko-Kontrollstellen übertragen dürfen. Insgesamt kann die Neuregelung als deutlicher Schritt zu einem vermehrt staatlichen und formalen Kontrollsystem betrachtet werden. Dieser institutionelle Wechsel bildet die Ausgangsbasis dieses Beitrages, der auf eine Befragung von 126 deutschen Öko-Landwirten beruht. Im Mittelpunkt der...

Soil fertility after 10 years of conservation tillage in organic farming Organic Eprints
Peigne, Joséphine; Vian, Jean François; Payet, Vincent; Saby, Nicolas.
It has become commonplace to consider ploughing as an agricultural practice that destroys soil fertility. Organic farmers have traditionally used the plough to till their soil and control weeds. However, there is a growing interest in adopting tillage practices without ploughing to preserve long-term soil fertility and in the hope, subsequently, of increasing crop yields. The aim of this paper is to assess if conservation tillage treatments in organic farming did in fact improve long-term soil fertility, wheat rooting and yield in a long term field experiment (2004–2015). We compared the effects of conservation tillage treatments (superficial tillage – ST- with chisel at 15 cm depth and very superficial tillage – VST- at 5–7 cm depth) and conventional...

Ikke så mens du høster Organic Eprints
Koesling, Matthias.
Dagens treskere har nådd et høyt teknisk nivå når det gjelder for eksempel renhet av korn i tanken, lite tresketap og vedlikeholdsbehov. Likevel må treskere ta en del av skylden for at det fortsatt vokser en god del frøugras i kornåkrene.

Vegetation in Danish field boundaries: A comparative study related to effects of agricultural practise Organic Eprints
Petersen, Sune.
Enrichment of biological diversity is often assumed to reflect good ecosystem integrity. Thus this variable has for some time been a key factor of management strategies and environmental programmes. The aim of the study presented here was primarily to observe, whether organic farming increases the biological diversity of field boundary vegetation when compared to conventional farming. Secondly, the aim was to consider, if increasing duration of the organic farming period also increases diversity. Finally, ecological interpretations of the data were given by comparing different agricultural practises in terms of general vegetation community patterns. The results documented that diversity of plant species was significantly higher within the organic...

Henry Shoobridge, Tasmania's Pioneer of Organic Farming Organic Eprints
Paull, John.
Henry Shoobridge (1874-1963) was the pioneer of organic farming in Tasmania. He was the founder and the president of the island’s earliest organics advocacy group, the Living Soil Association of Tasmania (1946- 1960). The Shoobridge family had emigrated from Kent, England in 1822 bringing with them the hops cuttings with which they established hops as a successful primary industry in Tasmania. Henry Shoobridge was schooled at The Friend’s School, the Quaker school in Hobart. The Shoobridges pioneered the farming of hops in Tasmania, and Henry followed his forebears in this work. At the age of 71 years, Henry Shoobridge founded the Living Soil Association of Tasmania (LSAT) at a public meeting in Hobart on 30 August 1946. The LSAT affiliated with the...

Absence of both glutathione perioxidase activity and glutathione in bovine milk Organic Eprints
Stagsted, J..
Glutathione peroxidases are selenium-dependent, antioxidant enzymes that catalyse the removal of hydroperoxides using the tripeptide glutathione as reducing substrate. The presence and importance of glutathione peroxidase for the oxidative stability of bovine milk is unclear. We failed to detect any specific activity in bovine milk using careful and comprehensive assay conditions. The apparent activity in milk that has been ascribed previously to glutathione peroxidase was shown to be independent of added hydroperoxide, completely inhibited by >6 mM EDTA, and could not be immunoprecipitated with a specific antiserum against the extracellular form of glutathione peroxidase. These results are incompatible with activity of glutathione peroxidase in bovine...

Hürden-Kombination bringt Sicherheit - Sichere und angepasste Herstellung von Öko-Fleisch- und -Wurstwaren ohne bzw. mit reduziertem Einsatz von Pökelstoffen Organic Eprints
Beck, Alexander; Dylla, Renate.
Bei der ökologischen Herstellung von Fleisch- und Wurstwaren werden vielfach auf die in der konventionellen Wurstherstellung verwendeten Konservierungsstoffe E 250 (Natriumnitrit) bzw. E 252 (Kaliumnitrat) verzichtet oder reduzierte Zugabemengen der Zusatzstoffe verwendet. Der Einsatz dieser Pökelstoffe in Öko-Fleisch- und Wurstwaren ist umstritten, da Nitrit toxikologisch nicht unbedenklich ist und es sich um eine chemisch-synthetisch hergestellte Verbindung handelt, die dem Grundsatz der Öko-Bewegung zur Minimierung des Einsatzes von Zusatzstoffen widerspricht. Jahrelange Diskussionen um die (Nicht-)Notwendigkeit des Einsatzes von Pökelstoffen und die zögerliche Haltung des Gesetzgebers führten zu Rechtsunsicherheiten in der ökologischen Fleisch- und...

Organic versus GMO farming: Contamination, what contamination? Organic Eprints
Paull, John.
A landmark case against the planting of GMO crops in Australia has delivered a big win for GMO farmers and produced no protection for organic farmers. The case pitted farmer against farmer. An organic farmer, Steve Walsh, initiated the legal action against his GMO growing neighbour, Michael Baxter in the Supreme Court of Western Australia. The Marsh and Baxter farms (477 hectares and 900 ha. respectively) are adjacent to each other and located in Kojonup, 260 km south east of the capital city of Perth in the wheat belt of Western Australia (WA) - and coincidentally nearby Broomhill was one of the earliest sites in the development of the organic movement in Australia (from 1930). Just before Baxter's first crop of Monsanto’s genetically modified (GM)...

Asian Spring for organic agriculture: Korea takes a lead Organic Eprints
Paull, John.
Korea’s Organic World Congress (OWC) was a milestone for Korea, for Asia, and for the world. It perhaps signals an Asian Spring for organics where Korea, in particular, and Asia, in general, are set to make rapid progress in meeting their aspirations and goals for reclaiming food and agriculture as organic. Korea’s OWC can serve to reinvigorate the momentum of organics in Asia where the organic statistics are dominated by the ‘organic giants’ of China and India. One remarkable enduring legacy of the OWC is the Namyangju Organic Museum. It is the world’s first museum dedicated to organic agriculture and was launched to coincide with the OWC. It is housed in a bold and strikingly modern new building. The museum presents a timeline of the history of organic...

Lite nitrogentap fra mjølkegarder som baserer seg på egen fôrprodukjson Organic Eprints
Steinshamn, Håvard; Bleken, Marina Azzaroli; Hansen, Sissel.
Tap av nitrogen (N) er et stort problem i landbruket, og i Europeiske direktiver blir det krevd forandring i landbrukspraksis for å redusere avrenningen. Ekstensiv mjølkeproduksjonen basert på heimeprodusert fôr er den mest effektive måten å bedre N-effektiviteten på. N-effektiviteten på gardsnivå reduseres dersom innkjøpet av fôr er høgt i forhold til planteproduksjonspotensialet på garden.

Bioraps: Erfolg auch in Finnland Organic Eprints
Hokkanen, H.; Menzler-Hokkanen, I.; Daniel, C..
In Finnland gibt es schon länger einen nennenswerten Anbau von Bioraps als bei uns. Nach einigen Startschwierigkeiten sind Finnlands Biobäuerinnen und Biobauern bei einer Anbaufläche von gegen 3000 Hektaren angelangt. Lernen können wir aus der finnischen Erfahrung vor allem zu den Themen Rapsglanzkäfer und Untersaaten. Seit etwa 10 Jahren werden in Finnland jährlich 2000–3000 Hektaren Biosommerraps angebaut. Einheimisches kalt gepresstes Biorapsöl ist nicht nur in Bioläden, sondern auch in den meisten Supermärkten erhältlich. Auch in Finnland übersteigt die Nachfrage immer noch das Angebot; die Ölpressen nehmen zurzeit nur noch Bioproduzenten neu unter Vertrag.

Effects of strip intercropping concept with perennial diversified grass-clover strip and annual winter rye-winter vetch intercrop as energy crops Organic Eprints
Hauggaard-Nielsen, Henrik; Johansen , Anders; Carter, Mette S.; Ambus, Per; Jensen, Erik Steen.
The combination of perennials and annuals in a strip cropping system is challenging primarily because the interspecific competitive ability of the perennials towards the annuals seems to be too dominating. Especially at the first harvest (tillering) closest to the adjacent grass-clover strip severe total dry matter production reductions was found ranging from 25%, 5% and 20% in the vetch SC, rye SC and vetch-rye IC, respectively. Rye in particular was suffering from the grass-clover interspecific competition with a SC yield of 700 g DM m-2 (0-25 cm) at maturity as compared to 1025 g DM m-2 when grown > 150 cm away. When grown >150 cm away from the grass-clover strip rye accumulate 8 g soil mineral N m-2,which is in the range of the expected according...

Quality of organic foods – a model for comparative analysis Organic Eprints
Vasileva, Elka; Ivanova, Daniela; Tipova, Nina; Stefanov, Stilian.
The quality and safety of organic products has been the subject of lively debate in the scientific community in recent years. The growing demand for organic food is based primarily on consumers’ concerns about the quality and safety and the perception that organic foods are healthier and safer than conventional foods. This paper identifies and makes analyses of comparative research studies on the quality of organic and conventional foods conducted over the last fifteen years. Based on the food quality science fundamentals a conceptual model for comparative testing of product quality is proposed. The model examines the dynamic relationship between its three basic components: "Designed Quality", "Perceived Quality" and "Achieved Quality". The proposed model...
