| 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... |

| Abstract The TILMAN-project aims to develop robust and sustainable arable crop production systems via the introduction of reduced tillage techniques combined with a strategic use of green manures in organic crop rotations, while maintaining and improving soil quality and crop productivity parameters. The adoption of reduced tillage and/or green manures strongly affects nitrogen quantity and availability during the vegetative period and throughout the crop rotation. Specifically, changing soil and water conditions may affect the availability pattern of nitrogen, notably in spring. We present aggregated data of several long- and medium-term European experimental field studies in which green manures including cut-and-carry-fertilizers, and reduced tillage... |

| 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... |

| 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... |

| 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... |

| 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... |

| Reduced tillage may improve the environmental and economic performance of organic farming. Reducing the intensity of soil tillage decreases the energy consumption and the emission of carbon dioxide, and could increase carbon sequestration (Holland 2004). Reduced tillage also may improve water retention and reduce soil erosion (Berner et al 2008). One of the main drawbacks of the reduced tillage practices is the potential increase of weed infestation and changes in weed species composition, sometimes to the benefit of species which are more difficult to control, such as perennial and grass species (Peigné et al 2007; Teasdale et al 2007; Sans et al 2011). Organic farmers commonly keep weeds under control by ploughing and by post-emergence mechanical... |

| 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... |
