Effects of landscape agricultural intensification and management on weed species richness in the edges of dryland cereal fields. Organic Eprints
Romero, Albert; Chamorro, Lourdes; Blanco-Moreno, José Manuel; Armengot, Laura; Jose María, Laura; Sans, Francesc Xavier.
An extensive survey of weed vegetation was conducted in the crop edges of 180 organic and conventional dryland cereal fields in nine localities of NE Iberian Peninsula to assess the effect of landscape agricultural intensification and management on weed diversity. This preliminary results show that averaged weed species richness per edge (alpha-diversity) and floristic homogeneity among edges are higher in organic than conventional fields. Only in conventionally managed fields, elevated landscape intensification is associated to higher weed alpha-diversities and floristic homogeneity among crop edges. The expression of high-quality weed flora is higher in organic than in conventional crop edges but, conversely, it is only sensitive to landscape...

Long-Term Management Affects the Community Composition of Arable Soil Seedbanks Organic Eprints
Rotchés-Ribalta, Roser; Armengot, Laura; Mäder, Paul; Mayer, Jochen; Sans, Francesc Xavier.
The intensification of farming practices has reduced weed infestations, but it has also led to a reduction in weed diversity and changes in species composition. These effects are well described for aboveground flora; however, it is less clear how these effects might be expressed in the soil weed seedbank. We evaluated the effects of different long-term farm management strategies on the weed seedbank abundance, diversity, and community composition in the DOK (bioDynamic, bioOrganic, and Konventionell) field trial established in 1978 at Therwil, Switzerland. The trial compares biodynamic, organic, and conventional farming systems, which mainly differ in fertilization, weed control strategies, and pest control. The species richness and seed abundance of the...

ORGANIC FARMERS IN EUROPE: MOTIVATIONS AND PROBLEMS FOR USING CONSERVATION AGRICULTURE PRACTICES. "TILMAN-ORG Session" Organic Eprints
Casagrande, Marion; Peigne, Joséphine; David, Christophe; Sans, Francesc Xavier; Blanco-Moreno, José Manuel; Cooper, Julia; Gascoyne, Kate; Antichi, Daniele; Bàrberi, Paolo; Bigongiali, Federica; Surböck, Andreas; Kranzler, Andreas; Beeckman, Annelies; Willekens, Koen; Luik, Anne; Peetsmann, Elen; Grosse, Meike; Heß, Jürgen; Clerc, Maurice; Dierauer, Hansueli; Mäder, Paul.
As conservation agriculture and organic farming are currently considered as environmentally friendly options for producing food, this study explores the motivations and problems of organic European farmers that apply at least two of the following techniques: (i) no-tillage, (ii) reduced tillage and/or (iii) green manures conservation practices. We carried out a survey about motivations and problems of 159 farmers located in 10 European countries with a questionnaire with closed-ended questions. Data were analysis with a principal component analysis followed by clustering to identify groups of farmers that share the same type of motivations and problems. The most important motivations are related to soil preservation concerns and problems are mainly linked...

Earthworm abundance response to conservation agriculture practices in organic arable farming under Mediterranean climate Organic Eprints
Baldivieso-Freitas, Paola; Blanco-Moreno, José M.; Gutiérrez-López, Mónica; Peigné, Joséphine; Pérez-Ferrer, Alejandro; Trigo-Aza, Dolores; Sans, Francesc Xavier.
Earthworms are one of the most important soil macrofaunal groups, and they play a major role in agricultural ecosystems. Agricultural practices, such as reduced tillage, the use of green manures and organic fertilization, can be beneficial for earthworm populations in agricultural systems. However, under a Mediterranean climate, not much is known regarding their response to agricultural management. The aim of this study was to analyse the effects of tillage type, organic fertilization, and green manures on the density and biomass of earthworms in organic arable dryland. The trial was conducted in a four-year crop rotation with a complete factorial design that combined tillage system (mouldboard ploughing vs. chisel), fertilization (composted farmyard...

DIVERSITY OF CONSERVATION AGRICULTURE PRACTICES AMONG EUROPEAN ORGANIC FARMERS “TILMAN-ORG SESSION” Organic Eprints
Peigne, Joséphine; Casagrande, Marion; David, Christophe; Sans, Francesc Xavier; Blanco-Moreno, José Manuel; Cooper, Julia; Gascoyne, Kate; Antichi, Daniele; Bàrberi, Paolo; Bigongiali, Federica; Surböck, Andreas; Kranzler, Andreas; Beeckman, Annelies; Willekens, Koen; Luik, Anne; Matt, Darja; Grosse, Meike; Heß, Jürgen; Clerc, Maurice; Dierauer, Hansueli; Mäder, Paul.
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,...

REDUCED TILLAGE AND COVER CROPS IN ORGANIC ARABLE SYSTEMS PRESERVES WEED DIVERSITY WITHOUT JEOPARDISING CROP YIELD Organic Eprints
Barberi, Paolo; Aendekerk, Raymond; Antichi, Daniele; Armengot, Laura; Berner, Alfred; Bigongiali, Federica; Blanco-Moreno, José Manuel; Carlesi, Stefano; Celette, Florian; Chamorro, Lourdes; Crowley, Oliver; Döring, Thomas; Grosse, Meike; Haase, Thorsten; Hess, Jürgen; Huiting, Hilfred; José-Maria, Laura; Klaedtke , Stéphanie; Kranzler, Andreas; Luik, Anne; Peigne, Joséphine; Sukkel, Wijnand; Surböck, Andreas; Talgre, Liina; Sans, Francesc Xavier.
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.
