Crop yield, weed infestation and soil fertility responses to contrasted ploughing intensity and manure additions in a Mediterranean organic crop rotation Organic Eprints
Baldivieso-Freitas, P.; Blanco-Moreno, José Manuel; Armengot, Laura; Chamorro, Lourdes; Romanyà, Joan; Sans, F. Xavier.
Conservation agriculture and organic farming are two alternative strategies that aim to improve soil quality and fertility in arable cropping systems through the deployment of different practices, that are rarely combined. While conservation agriculture practices include reducing tillage intensity and maintaining soil cover all year round to prevent soil erosion, organic farming focuses on nutrient recycling, using farmyard manure and green manure to enhance soil quality. However, these practices are not free from side-effects, such as increasing weed infestation or limited nutrient availability. Therefore it is necessary to explore the sustainability of their combination under local environmental constraints. The objectives of this study were to evaluate...

Efecto del laboreo mínimo (chisel), la fertilización y los abonos verdes sobre la flora arvense y los rendimientos en una rotación de cultivos de cereales y leguminosas ecológicos Organic Eprints
Chamorro, Lourdes; Baldivieso-Freitas, P.; Blanco-Moreno, José Manuel; Armengot, Laura; Sans, F. Xavier.
Effects of reduced tillage, fertilization and green manures on the weeds and crop yields in a cereal-legume crop rotation under organic farming. On 2011, we established a long-term experiment to evaluate the effects of reduced tillage (chisel vs mouldboard plough), fertilization with semicomposted manure and sowing of green manures before spring crops, on the crop yields and weed abundance in a 5-year rotation (spelt, chickpea, wheat, lentil and spelt). After five years, there was not noticeable increment in weed abundance or richness. Reduced tillage caused a significant increase of weeds compared with mouldboard plough, but it this increase did not cause significant yield loss in cereal crops compared with mouldboard plough. Green manures exerted a...

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...

ORGANIC FARMING ENHANCES THE RECOVERY OF ANCIENT CROPS AND SEGETAL WEEDS IN CATALONIA (NE OF SPAIN) Organic Eprints
Chamorro, Lourdes; Armengot, Laura; José-María, Laura; Sans, F. Xavier.
The Area of Natural Interest of Gallecs (ANIG) is one of the largest areas of arable land managed organically in Catalonia. In 2005 a project was launched to convert fields to organic farming and recuperate traditional crop varieties. The aim of this work is to analyse the changes in diversity of the weed flora, including segetal and rare species, and of crops in 20 fields (ca. 50 ha) after the conversion to organic farming during 5 cropping periods (2005-2010). Number of cultivated crops has increased from 1 to 17 including ancient and local varieties of cereal and legumes. Weed biodiversity increased by a 50% in five years at field and regional scale. Crop rotations and sowing organic seeds from other farmers can contribute to the increase and the...

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.

The role of intercropping on insects diversity in dryland field crops in a Mediterranean site Organic Eprints
Caballero, Berta; Romero, Albert; Perez, Nicolas; Ventura, Daniel; Chamorro, Lourdes; Goula, Marta; Sans, F.Xavier.
This work aims to evaluate the effect of crop type and density on insects’ community in the Mediterranean re-gion. In winter of 2004, four 35m x 10m blocks (replicates) were delimited and 24 equidistant 2m x 3m plots were marked. Seven crop types (barley, vetch, turnip, barley-vetch, barley-turnip, vetch-turnip and barley-vetch-turnip) at three densities were randomly established within each block. Fifteen crop shoots per plot were randomly collected in May to evaluate insect’s abundance and diversity. Our results suggest that inter-crop has a positive effect on abundance of most exam-ined groups of insects and diversity, specifically when vetch is incorporated in the mixture. Changes in abun-dance of aphids, trips and ants are also discussed connected...
