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...

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...

The interest of organic farmers for adopting conservation agriculture practices is currently growing. But, there are few technical and scientific references available for organic farmers when they start applying conservation agriculture practices. The main objectives of this study are (1) to explore the diversity of crop management practices using conservation agriculture methods among European farmers, and (2) to identify main farmers’ strategies. We carried out a survey of 159 farmers located in 10 European countries with a questionnaire with closed-ended questions. Data were analysis with a multi factor analysis followed by clustering to identify groups of farmers that share the same type of spring and winter crop managements. Organic farmers in Europe,...

Energieeffiziente Bodenbearbeitung im biologischen Ackerbau Organic Eprints
Theurl, Michaela Clarissa; Hörtenhuber, Stefan Josef; Surböck, Andreas.
Soil management techniques require both in conventional and organic agricultural systems high amounts of energy which are related to the emissions of greenhouse gases and climate change as well as an increasing dependence on fossil fuels. This paper examines ecological and economic effects of reduced tillage techniques and ploughing over two years with the crops winter wheat and sugar beet. The tillage trial was carried out on a Chernozem soil in a semi-arid region in Austria. The results show 31 % lower energy consumption for reduced tillage over both crops. Interestingly, the ploughing variant resulted in 12 % higher sugar beet yield, but showed 12 % lower wheat yields per hectare. An economic evaluation of both variants did not identify differences over...

Erhöhung der Klima-Resilienz in einem ökologischen Ackerbausystem: auf die Kombination von Strategien kommt es an! Organic Eprints
Friedel, Jürgen K.; Gollner, Gabriele; Surböck, Andreas; Freyer, Bernhard.
Die Klimawandel-bedingte Zunahme von Trockenperioden in Gegenden mit geringen Niederschlägen erfordert Anpassungsstrategien im ökologischen Ackerbau. Außer trockenheitstoleranten Sorten wurden in einem Langzeitversuch auf einem viehlosen Ackerbaubetrieb in der semi-humiden Region im Osten Österreichs vier hauptsächliche Strategien gemeinsam angewandt: eine Futterleguminosen-basierte Fruchtfolge mit Zwischenfruchtgemengen, organische Düngung mit Luzernemulch, Biokompost oder Stallmist, reduzierte, nicht-wendende Bodenbearbeitung und Gehölzstrukturen. Mit diesen kombinierten Strategien waren die Humusgehalte stabil bis ansteigend, die Wasserinfiltration und pilzliche Biomasse im Oberboden wurden gefördert, die Erträge der Marktfrüchte waren...

How organic farmers practice conservation agriculture in Europe Organic Eprints
Peigne, Joséphine; Casagrande, Marion; Payet, Vincent; David, Christophe; Sans, F. Xavier; Blanco-Moreno, José M.; Cooper, Julia; Gascoyne, Kate; Antichi, Daniele; Bàrberi, Paolo; Bigongiali, Federica; Surböck, Andreas; Kranzler, Andreas; Beechman, Annelies; Willekens, Koen; Luik, Anne; Matt, Darja; Grosse, Meike; Heß, Jürgen; Clerc, Maurice; Dierauer, Hansueli; Mäder, Paul.
The interest of organic farmers in adopting conservation agriculture principles, including minimal soil disturbance, permanent soil cover and crop rotation has been growing since the early 2000s. However, currently there is no network for organic farmers practicing conservation agriculture, and a lack of knowledge on how organic farmers implement conservation agriculture in practice. Consequently, few technical references are available for organic farmers when they start applying conservation agriculture practices, in particular on controlling weeds without the use of herbicides. The main objectives of this study were: (1) to explore the diversity of conservation agriculture techniques (i.e., reduced tillage, no-tillage and green manures) practiced among...

Conservation agriculture and organic farming are considered as promising sustainable agricultural system for producing food, while minimizing environmental impacts. Despite an increasing number of experimental data on organic conservation practices and various studies dealing with the adoption of conservation agriculture by farmers, none of those studies have specifically addressed conservation agriculture adoption under organic conditions in Europe. We carried out a survey with 159 farmers located in 10 European countries. These farmers had applied at least two of the following conservation practices: (i) no-tillage, (ii) reduced tillage and (iii) green manures. Each farmer assessed socio-economic, agronomic and environmental motivations and problems for...

One of the objectives of the TILMAN-ORG Project is to improve weed management under conservation agriculture (reduced tillage and/or cover crops) in organic arable systems. The shift from ploughing to conservation agriculture should not only maintain crop yield but possibly improve weed community diversity. This paper summarises the results on (1) weed abundance, (2) weed diversity and (3) crop yield obtained in the first year of the project (2012) in 13 trials scattered across Europe.

Soil quality changes in field trials comparing organic reduced tillage to plough systems across Europe (TILMAN-ORG Session) Organic Eprints
Fliessbach, Andreas; Hammerl, Verena; Antichi, Daniele; Barberi, Paolo; Berner, Alfred; Bufe, Cornelia; Delfosse, Philippe; Gattinger, Andreas; Grosse, Meike; Haase, Thorsten; Heß, Jürgen; Hissler, Christophe; Koal, Phillip; Kranzler, Andreas; Krauss, Maike; Mäder, Paul; Peigné, Joséphine; Pritsch, Karin; Reintam, Endla; Surböck, Andreas; Vian, Jean François; Schloter, Michael.
Field trials on reduced soil tillage under organic farming conditions across Europe were used to compare the soil quality changes over time. Soil organic carbon fractions, soil carbon stocks and microbial community structure were analysed. Most severe differences between plough and reduced tillage were found in the top ten cm of the soil profile. Differences became less or not significant in deeper layers. Analyses are still ongoing and will only be ready to be presented at the conference.
