Can weed management in vegetable systems be improved by cover crop species mixture? Step 1: Screening of cover crop species and varieties Organic Eprints
Ranaldo, Marzia; Costanzo, Ambrogio; Carlesi, Stefano; Barberi, Paolo.
Cover crops are an essential strategy in organic and low input arable and vegetable production, especially regarding weed reduction and N use efficiency, but their establishment and development can be unstable. A viable option to enhance and stabilise the agroecosystem services provided by cover crops is to sow mixtures of species having different functionality. Such mixtures have been reported to increase productivity, stability, resilience and resource use efficiency of cover crop communities. Therefore, our hypothesis is that weed reduction can also be improved by cover crops mixtures. However, it is not yet clear how diversity drives these mechanisms in arable and vegetable systems in Mediterranean climates.

EFFECT OF CONSERVATION PRACTICES ON FUNCTIONAL DIVERSITY AND ASSEMBLY OF WEED COMMUNITIES: A DATABASE OF FUNCTIONAL TRAITS Organic Eprints
Sans, F. Xavier; Armengot, Laura; Blanco-Moreno, José Manuel; Bocci, Gionata; Carlesi, Stefano; Barberi, Paolo.
The incorporation of conservation agriculture techniques (e.g. reduced tillage and green manures) in organic farming systems brings many benefits to the environment and reduces energy use (Holland, 2004). One of the main drawbacks of the use of reduced tillage is the potential increase in weed infestation and shifts in the weed community composition, sometimes to the benefit of more difficult-to-control species (Bàrberi, 2002; Peigné et al., 2007; Sans et al., 2011). However, weeds have an important role in maintaining farmland functional biodiversity (Bàrberi et al, 2010; Caballero et al., 2010), and this should be balanced with their potential negative impact on crop yield and quality. Within the frame of the European project “Reduced tillage and green...

Hairy vetch cover crop affects weed diversity and composition in no-till sunflower Organic Eprints
Carlesi, Stefano; Antichi, Daniele; Sbrana, Massimo; Barberi, Paolo.
Vicia villosa Roth, or hairy vetch, is one of the most productive cover crops (CC) in Mediterranean dry areas, with an interesting potential as dead mulch in no-tillage cropping systems. In low-input cropping systems, mechanical termination of hairy vetch could replace a glyphosate application to control weeds. Mechanical termination (e.g. with a roller crimper) of hairy vetch is ineffective until the late growing stages of vetch, leading to delayed sowing and yield reduction in the following crop. To find the best compromise in timing between effective termination of vetch and reasonable yield of no-till sunflower, an on-farm experiment was carried out in Pisa (Italy) in 2012/13 and 2013/14 to compare three termination techniques (roller crimper with no,...

Integrating Physical and Cultural Methods of Weed Control – Examples from European Research Organic Eprints
Melander, Bo; Rasmussen, Ilse A.; Barberi, Paolo.
Increasing concerns about pesticide use and a steadily increasing conversion to organic farming have been major factors driving research in physical and cultural weed control methods in Europe. This paper reviews some of the major results achieved with non-chemical methods and strategies especially adapted for row crops (e.g. corn, sugar beet, onion, leek, and carrot) and small grain cereals (e.g. barley and wheat). In row crops, intra-row weeds constitute a major challenge and research has mainly aimed at replacing laborious hand weeding with mechanization. A number of investigations have focussed on optimising the use of thermal and mechanical weeding methods against intra-row weeds, such as flaming, harrowing, brush weeding, hoeing, torsion weeding...

Las malas hierbas como bioindicadores del suelo: Cómo muestrear y usar los datos Organic Eprints
Carlesi, Stefano; Barberi, Paolo.
Esta ficha técnica describe cómo las especies de malas hierbas pueden ser utilizadas como bioindicadores de las condiciones del suelo, relacionándolas con las características del suelo (como pH o textura)y al manejo del suelo (como el uso del agua, falta o exceso de nutrientes o compactación. Debe destacarse que (i) este tipo de análisis no siempre proporciona resultados consistentes, porque la relación entre las malas hierbas y las condiciones del suelo no siempre es clara y que (ii) la metodología de muestreo sugerida requiere conocimientos botánicos básicos para la identificación de especies.

Long term effects of cover crops on weeds in Mediterranean low input arable management systems Organic Eprints
Carlesi, Stefano; Antichi, Daniele; Bigongiali, Federica; Mazzoncini, Marco; Barberi, Paolo.
The introduction of cover crops (CC) in crop rotations is a key tool to control weed and ameliorate soil conditions in low input arable systems. In 1992 a long term experiment (LTE) was set up at Centre for Agri-environmental Research “E. Avanzi (CIRAA), University of Pisa to determine the combined effect of tillage intensity, nitrogen fertilization levels and CC types on soil quality, crop yield and weed communities. The LTE is based on 4-year crop rotation (maize, durum wheat, sunflower, durum wheat) with cover crops grown twice, in between wheat and summer crops. Two tillage systems were compared: i) a conventional system (CS), with annual ploughing (30 cm depth); ii) a low input system (LIS), with chiseling (30 cm depth) for summer crops and no...

Organic farmers’ motivations and challenges for adopting conservation agriculture in Europe Organic Eprints
Casagrande, Marion; Peigne, Joséphine; Payet, Vincent; Mäder, Paul; Sans, F. Xavier; Blanco-Moreno, José Manuel; Antichi, Daniele; Barberi, Paolo; Beeckmann, Annelies; Bigongiali, Federica; Cooper, Julia; Dierauer, Hansueli; Gascoyne, Kate; Grosse, Meike; Heß, Jürgen; Kranzler, Andreas; Luik, Anne; Peetsmann, Elen; Surböck, Andreas; Willekens, Koen; David, Christophe.
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...

PHYSICAL AND CULTURAL WEED CONTROL IN MINOR CROPS Organic Eprints
Melander, Bo; Barberi, Paolo.
This paper summarises the major European achievements with physical and cultural weed control methods in minor row crops. Minor crops, such as vegetables, sweet maize and potatoes, present two different situations for physical weed control of entirely different difficulty. Inter-row weeds are easily removed by inter-row cultivation while intra-row weeds, i.e. those growing between the crop plants in the rows, still constitute a major challenge aimed at minimising laborious hand weeding. Investigations have focussed on optimising the use of mechanical principles against intra-row weeds, e.g. harrowing, brush weeding and finger weeding. These methods have been successful in some transplants, potatoes and maize, and may become alternatives to chemical...

Pleveli kot bioindikatorji: vzorčenje in uporaba podatkov Organic Eprints
Carlesi, Stefano; Barberi, Paolo.
Članek opisuje uporabo plevelnih vrst kot indikator-jev stanja tal, ki je povezano ali z lastnostmi tal (kot sta pH ali tekstura tal) ali z gospodarjenjem s tlemi (zastajanje vode v tleh, premalo ali preveč hranil, zbitost). Poudariti je treba, da: (i) Tovrstna analiza ne zagotavlja vedno doslednih rezultatov. Odnos med različnimi plevelnimi vrstami in stanjem tal namreč ni vedno jasno začrtan. (ii) Za izvajanje te metode vzorčenja je potrebno nekaj osnovnega botaničnega znanja za identifikacijo plevelov.

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.

Shallow non-inversion tillage in organic farming maintains crop yields and increases soil C stocks: a meta-analysis Organic Eprints
Cooper, Julia; Baranski, Marcin; Stewart, Gavin; Nobel-de Lange, Majimcha; Barberi, Paolo; Fliessbach, Andreas; Peigne, Joséphine; Berner, Alfred; Brock, Christopher; Casagrande, Marion; Crowley, Oliver; David, Christophe; De Vliegher, Alex; Döring, Thomas F.; Dupont, Aurélien; Entz, Martin; Grosse, Meike; Haase, Thorsten; Halde, Caroline; Hammerl, Verena; Huiting, Hilfred; Leithold, Günter; Messmer, Monika; Schloter, Michael; Sukkel, Wijnand; van der Heijden, Marcel G. A.; Willekens, Koen; Wittwer, Raphaël; Mäder, Paul.
Reduced tillage is increasingly promoted to improve sustainability and productivity of agricultural systems. Nonetheless, adoption of reduced tillage by organic farmers has been slow due to concerns about nutrient supply, soil structure, and weeds that may limit yields. Here, we compiled the results from both published and unpublished research comparing deep or shallow inversion tillage, with various categories of reduced tillage under organic management. Shallow refers to less than 25 cm. We found that (1) division of reduced tillage practices into different classes with varying degrees of intensity allowed us to assess the trade-offs between reductions in tillage intensity, crop yields, weed incidence, and soil C stocks. (2) Reducing tillage intensity in...

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.

SOILapp Organic Eprints
Barberi, Paolo; Guidotti, Diego; Lazarro, Mariateresa; Conte, Luca; Vakali, Christina.
SOILHEALTH.CAPSELLA.EU platform supports farmers across Europe in maintaining healthy agricultural soils. The spade-test application on the platform allows self-assessment of soil health using a widely used, qualitative method for performing the observation of soil conditions (spade test). It gives the farmer information on soil fertility and on mechanical operations effects on its structure. Farmers, by using the application for recording their observations, are able to share their findings, learn from each other and seek further advice to the community by working with open software, open data and open hardware. The spade test application, available for PC, tablet and smartphone, guides the user through an easy touch-enabled interface to define the soil...

Weeds as soil bioindicators: How to sample and use data Organic Eprints
Carlesi, Stefano; Barberi, Paolo.
This technical note shows how weed species can be used as indicators of soil conditions that are either linked to soil characteristics (such as soil pH or texture) or to soil management (such as water logging, lack or excess of nutrients, compaction). It should be stressed that (i) this kind of analysis does not always provide consistent results, because the relationship between weed species and soil conditions is not always clear cut and that (ii) the suggested sampling methodology requires some basic botanical skills for weed identification.
