Alleanze tra Agricoltori e Consumatori – Come comunicare con successo il valore degli alimenti biologici ai consumatori Manuale pratico Organic Eprints
Zander, Katrin; Hamm, Ulrich; Freyer, Bernhard; Gössinger, Katharina; Hametter, Monika; Naspetti, Simona; Padel, Susanne; Stolz, Hanna; Stolze, Matthias; Zanoli, Raffaele.
Il risultato principale della nostra ricerca ha confermato che la comunicazione degli attributi etici addizionali offre a molte aziende biologiche una reale opportunità di differenziazione dei propri prodotti nel più vasto mercato biologico. Molti consumatori e produttori sono d’accordo sul fatto che la produzione biologica in conformità al regolamento UE sull’agricoltura biologica (834/2007) non rappresenta la ‘fase finale’ in riferimento a una produzione alimentare sostenibile ed etica. Un numero crescente di consumatori acquista prodotti che siano realizzati secondo standard ‘etici’ non attualmente ricompresi nelle norme previste dal regolamento UE sull’agricoltura biologica o che – in ogni caso – vanno al di là degli standard minimi ivi previsti....

Anbauverfahren „Weite Reihe“ von Winterweizen unter den kontinentalen Anbaubedingungen Ostösterreichs Organic Eprints
Wagentristl, Helmut; Pietsch, Gabriele; Freyer, Bernhard.
Problemstellung und Ziele: Winterweizen mit 12% Protein wird in der Regel gesichert nur nach kleinsamigen Leguminosen wie Rotklee oder Luzerne mit einem hohen Stickstoffangebot aus den mineralisierten Ernte-Wurzelrückstanden erreicht. Um dieses Qualitätsziel auch im viehlosen Anbau in niederschlagsarmen Regionen zu erreichen, wurden anhand von Feldversuchen verschiedene Saatstärken und Reihenabstände geprüft.

ARBUSCULAR MYCORRHIZA OF WINTER WHEAT UNDER DIFFERENT DURATION OF ORGANIC FARMING Organic Eprints
Gollner, Manfred; Friedel, Jürgen; Freyer, Bernhard.
The effect of continuous organic farming (OF) on the arbuscular mycorrhizal fungi (AMF) of winter wheat (Triticum aestivum) was investigated in a greenhouse pot trial. Representative soil samples were taken from 5 farms in the “Weinviertel” region, northeast of Vienna, Austria. On each farm three sites with a different duration of OF were selected for soil sampling; wheat was used as test plant. The mycorrhizal colonization (MC), root length density (RD) and the mycorrhizal colonized root length density (MD) were evaluated for the wheat roots. The majority of the wheat plants indicated an increasing MC and MD with increasing duration of OF. Based on our results we assume that a conversion period from conventional to OF of approximately 15 years is needed...

Auswirkungen unterschiedlicher Haupt- und Zwischenfrucht-Kombinationen auf Ertrag und den Schaderregerbefall der Folgefrucht Kartoffel Organic Eprints
Surböck, Andreas; Schiessendoppler, Elisabeth; Ledermüller, Johann; Friedel, Jürgen; Freyer, Bernhard.
Infections with diseases like black scurf (Rhizoctonia solani) and common scab (Strep-tomyces scabies) cause tuber blemishes. In addition, black scurf has an adverse impact on tuber yield, size and shape. The aim of the study was to assess the effect of combinations of main and catch crops on tuber yield, quality and sanitary status. The tested variants were: var. 1: pea without a catch crop apart from volunteer peas, var. 2: pea with a catch crop consisting of white mustard, California bluebell and volunteer peas, var. 3: oat without a catch crop, var. 4: oat with an underseed of white clover. Although in the variants tested no significant difference was achieved for tuber yield, disease occurrence and degree of infection with black scurf and common scab,...

Auswirkungen unterschiedlicher Luzerneanteile in der Fruchtfolge auf Humus- und Stickstoffhaushalt Organic Eprints
Surböck, Andreas; Heinzinger, Markus; Schmid, Harald; Friedel, Jürgen K.; Freyer, Bernhard.
Fodder legumes, like lucerne, make a significant contribution to a positive humus balance and nitrogen supply on organic farms. To determine the required lucerne percentage to meet these targets, several shares of lucerne were modelled on the basis of empirical data of an eight-field crop rotation. The lower limit for ensuring optimum humus and nitrogen supply in this rotation was approximately 17 % lucerne. The calculation of the data was performed with the agricultural software REPRO.

Auswirkungen unterschiedlicher Vorfrüchte und Düngungssysteme auf Ertrag und Qualität von Winterweizen Organic Eprints
Surböck, Andreas; Friedel, Jürgen K.; Heinzinger, Markus; Schweinzer, Agnes; Freyer, Bernhard.
The effect of different preceding crops and fertilisation systems on winter wheat yieldand quality was assessed in a long-term field experiment in Eastern Austria. Winter wheat following a 2-years lucerne crop had lower yield but higher protein content than winter wheat following peas. Lucerne green manure use in a stockless system increased yield and protein content of a subsequent wheat crop compared to a livestock-keeping system with removal of the lucerne crop for fodder use. Wheat following peas that had received farmyard manure in the livestock-keeping system only, showed higher yield than in the stockless system but no differences in protein content. Likewise, an additional compost fertilisation in the stockless system increased yield of wheat...

Auswirkungen verschiedener Bodenbearbeitungsvarianten auf den Besiedelungsgrad von Winterroggen (Secale cereale) durch arbuskuläre Mykorrhizapilze (AMP) unter den Bedingungen des Ökologischen Landbaues Organic Eprints
Gollner, Manfred; Friedel, Jürgen; Freyer, Bernhard; Hampl, Ulrich.
Problemstellung/Ziele:Die arbuskuläre Mykorrhiza ist eine Symbiose zwischen dem Grossteil der landwirtschaftlichen Kulturpflanzen und bodenbürtigen Pilzen. Der heterotrophe Pilz erhält Assimilate von der autotrophen Pflanze, als Gegenleistung fördert der Pilz die Nährstoffaufnahme in die Pflanze und erhöht die Resistenz gegenüber phytopathogenen Mikroorganismen, die in einer Wachstumssteigerung der Pflanze resultieren können. In zahlreichen Untersuchungen wurde festgestellt, dass mechanische Bodenbearbeitung das Besiedelungspotenzial von landwirtschaftlichen Kulturpflanzen durch arbuskuläre Mykorrhizapilze (AMP) vermindert und die Effizienz des Myzels der AMP bei der Aufnahme von Phosphor mit steigender Intensität der Bodenbearbeitung abnimmt.

Biodiversität – eine komplexe zeit-räumliche agrarökologische Herausforderung für den Ökolandbau Organic Eprints
Freyer, Bernhard; Surböck, Andreas; Heinzinger, Markus; Friedel, Jürgen K.; Bernhardt, Karl-Georg; Bruckner, Alexander; Straka, Ulrich; Reiter, Andreas.
One year after the conventional farm started the conversion process in 2002, a long term farming system monitoring was established in the Eastern region of Austria. The goal was to evaluate the performance of organic arable farming and its biotopes (flowering stripes, hedges and tree rows), and specifically their impact on biodiversity. After nine years organic farming we note a considerable increase of biodiversity in the arable fields and accompanying biotopes. Indicators applied were soil fauna, breeding birds as well as weeds. Space-time aspects, rotation and management measures as well as crop specific characteristics were influencing the development of species diversity. The development of diversity however is limited due to the intense farming in...

Communication of ethical activities going beyond organic standards in European organic enterprises Organic Eprints
Gössinger, Katharina; Freyer, Bernhard.
In times of rapid growth of the organic market and differentiation processes within the sector, efforts are made on different levels to (re)define and strengthen organic values. The normative part of this process is the reformulation of IFOAM-principles, which form the basis for ethical commitment within the organic movement, without being fully integrated into organic regulations. This article addresses the question of which ethical activities are practised on organic farms and by organic companies that go beyond the organic regulations (referred to as "organicPlus" in this study), with what arguments these activities are communicated to consumers and how they are related to the dimensions of sustainability. The survey encompasses 100 small and...

Consumer concerns regarding additional ethical attributes of organic food Organic Eprints
Zander, Katrin; Hamm, Ulrich; Freyer, Bernhard; Goesssinger, Katharina; Naspetti, Simona; Padel, Susanne; Stolz, Hanna; Stolze, Matthias; Zanoli, Raffaele.
In a world where more and more organic products are mass produced, and where most consumers have little – if any – contact with the organic farmers who have produced their food, many people feel that the underlying principles of the organic movement are coming under threat. According to our research consumers are mostly interested in additional ethical attributes like “higher animal welfare standards”, “regional/local production” and “fair producer prices” and they are willing to pay more for organic products which are produced following these higher standards. This gives producers the opportunity to differentiate their products in the organic market. When communicating these additional ethical attributes of organic food producers must take care to use a...

Corporate Social Responsibility and Organic Farming –Experiences in Austria Organic Eprints
Gössinger, Katharina; Freyer, Bernhard.
Although the market for organic products has been growing in Austria for a few years, the rising competition of so called regional, natural or sustainable products should be taken seriously. One solution in times of “conventionalisation” of organic farming could be higher ethical standards in organic farming and more effective communication of ethical values, as it has already been practised by a great number of medium-sized and large enterprises under the name of “Corporate Social Responsibility” (CSR). CSR refers to all services that are beyond legal requirements, performed on a voluntary basis. This article discusses the topic CSR and similar approaches in the Austrian organic sector on the basis of 30 interviews with Austrian organic farmers and...

Corporate Social Responsibility: oft gelebt - selten kommuniziert. [Corporate Social Responsibility: often praticed - rarely communicated] Organic Eprints
Gössinger, Katharina; Freyer, Bernhard.
Corporate Social Responsibility (CSR) gewann in den letzten Jahren in Mitteleuropa enorm an Bedeutung und wird heute bereits von zahlreichen österreichischen Unternehmen in ihre Firmenstrategie miteinbezogen. Doch was steckt hinter dem Konzept, das seinen Ausgang im angloamerikanischen Raum nahm? Ist CSR ein bloßer Marketinggag, oder gelebte Verantwortung? Wie werden CSR-ähnliche Leistungen der Landwirtschaft in der Gesellschaft wahrgenommen? Welche Rolle spielt CSR in der österreichischen Lebensmittelbranche? Welche Bedeutung haben CSR und ähnliche Ansätze im Biobereich?

Der biologische Landbau in Österreich – Entwicklungen und Perspektiven Organic Eprints
Freyer, Bernhard; Eder, Michael; Schneeberger, Walter; Darnhofer, Ika; Kirner, Leopold; Lindenthal, Thomas; Zollitsch, Werner.
In den Jahren 1994 bis 1998 hatte der biologische Landbau in Österreich bisher seine stärkste Entwicklung. Die frühe Verankerung von Richtlinien für biologische Produkte pflanzlicher und tierischer Herkunft im österreichischen Lebensmittelbuch, die staatliche Förderung der Umstellung bzw. der Biobetriebe, günstige Bedingungen im Absatz durch den Einstieg der Supermarktketten, die Gründung einer Vermarktungsgesellschaft, eine aktive Verbandspolitik und der Ausbau der Beratung haben dazu beigetragen, dass Österreich in Europa den höchsten Anteil an Biobetrieben erreichte. Ende der neunziger Jahre hat sich diese dynamische Entwicklung nicht fortgesetzt. Ob die Krisen in der konventionellen Landwirtschaft einen neuerlichen Aufschwung durch eine anhaltend...

Die Soziale Innovationskraft des Ökologischen Landbaus – zwischen Main Stream und Gesellschaftlichem Wandel Organic Eprints
Fiala, V.; Freyer, Bernhard.
In this article we present a conceptual framework to describe and assess how conversion towards organic farming can qualify as a social innovation (SI). For that we critically analyze the current concepts on SI and add insights from Practice Theory (PT) to create an instrument to apply the idea of SI within the context of organic agrofood-systems. We introduce an example and conclude with a summary of the added value of an extended concept of SI using insights from PT.

Effect of plant biomass and their incorporation depth on organic wheat produc-tion in Kenya Organic Eprints
Birech, Rhoda; Freyer, Bernhard.
Intensive agricultural technologies introduced in Africa some six decades ago paved the way for extensive land clearing and destruction of organic materials, development of high yielding crop varieties under monoculture and replacement of landraces. Si-multaneously, pesticides and antibiotics for use in agricultural pest and disease control were being developed and soon the face of agriculture was transformed by what was termed the Green Revolution. However, the apparent success accruing from such heavy investment was short-lived since the system would easily succumb to soil erosion, reduced soil organic matter, environmental pollution and pest and disease outbreaks. The inevitable result is the inability of land to sustain food productivity and worsening...

Einfluss von Luzernebeständen auf den mikrobiellen Kohlenstoff und Stickstoff in der Ackerkrume und im Unterboden im pannonischen Klimaraum Ostösterreichs Organic Eprints
Friedel, Jürgen K; Farthofer, Renate; Pietsch, Gabriele; Freyer, Bernhard.
In ostösterreichischen Ackerbaugebieten ist auch im Ökologischen Landbau die viehlose Bewirtschaftungsform üblich. Der Hauptanteil des Stickstoffbedarfes wird über den Einsatz von Futter- und Körnerleguminosen sowie Leguminosen im Zwischenfruchtanbau gedeckt. Die Nutzung von Futterleguminosen erfolgt als Gründüngung, bei der der Aufwuchs am Feld verbleibt (Mulch). Die Leguminose wird als Reinkultur oder im Gemenge mit Gras angebaut. Es sollte geklärt werden, ob durch die Wurzelmasse und das tiefreichende Wurzelsystem unter Futterleguminosenbeständen die mikrobielle Biomasse bereits nach einmaligem, überjährigen Anbau von Leguminosen, v.a. im Unterboden, gefördert wird. Weiters wurde untersucht, ob Unterschiede aufgrund der Art des Nutzungsregimes (Mulch...
