| 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 Here, we compiled the results from both published and unpublished research comparing deep or shallow inversion tillage, with various categories of reduced tillage under organic management.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... |

| 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... |

| Organic farming is considered as a solution to preserve water quality in drinking water catchments. For local managers of these catchments it is thus important to identify conventional farmers for potential conversion to organic farming. The aim of this article is to assess technical similarity of conventional farmers concerned by a water catchment to organic farming. We build a typology of farmers based on technical logics related to cropping systems organization. We differentiated five types of farmers among 18 conventional dairy farmers and three recently converted organic farmers. According to our results, only two farmers can be considered as close to technical logics identified in organic farms. Nevertheless, we could identify partial technical... |

| French organic farmers are asked to increase Grain Protein Content (GPC) of organic winter wheat to guarantee the breadmaking quality required from millers. Facing with the recent depletion of organic products, farmers also need to stabilize and increase the yield performance. The aim of our study is to give the explanations of the yield and GPC variability generally observed in organic production. A diagnostic method will be implemented on a network of ca. 10 fields per year during two crop years added with previous field network (77 fields) and experi-ments (4 experiments on cultivars). We will under-stand yield and GPC performance from environmental and agronomic conditions and relate the observed limiting factors with crop management, climatic... |

| One of the tasks of the TILMAN-Org project is to assess organic farmers' experiences and perceptions about reduced tillage and green manures. We carried out a survey with around 150 organic farmers that applied at least two out of the 3 following techniques: no tillage techniques, reduced tillage techniques and green manure techniques in 8 partner countries (Austria, Belgium, Estonia, France, Germany, Italy, Spain, Switzerland and UK). The questionnaire addressed the motivations and major problems when adopting each conservation technique. We also collected data on the detailed crop management of one winter and one spring crop per farm (especially tillage and green manure management). The objectives of the data analysis are to: (i) identify farmers’... |

| The acquired information on biomass production and expected nutri-ent release of cover crop species and/or cultivars will provide greater certainty for the selection of suitable varieties and the estimation of fulfilment of the nutrient requirements of the subsequent crop. Method and results of practical testing MERCI is an easy-to-use tool which simplifies: • Estimation of the dry matter produced per hectare (tonnes per hectare); • Calculation of the nitrogen trapped (or stored) by the cover crop; • Definition of the nitrogen refund levels for the subsequent crop (kg/ha). The references used in the calculations are based on more than 10 years of trials on cover crops in Poitou-Charentes/France. Simulations are carried out with INRA's STICS... |

| A regional agronomic diagnosis was implemented to identify factors responsible for low values of Grain Protein Content (GPC) in a network of 35 organic winter wheat fields in South-Eastern France. The influence of water nutrition, radiation and temperature, weed density at flowering, nitrogen (N) status of crop at flowering and variety type were studied. Two statistical methods were used successively: classical linear regression and a mixing model approach based on a weighted sum of all possible linear combinations of explanatory variables. GPC was significantly related to variety type, crop N status and weed density. An analysis of variance showed that weed density was related to soil type and nitrogen supply. |

| Les cultures intermédiaires multi services, ou CIMS, jouent un rôle essentiel en agriculture biologique (AB) du fait des nombreux services écosystémiques qu’elles peuvent rendre. La capacité des CIMS à apporter des nutriments à la culture suivante est particulièrement intéressante en AB en raison de la faible disponibilité en engrais. Les CIMS visent également de maintenir la teneur en matière organique des sols essentielle à leur fertilité en compensant les exportations des récoltes. Elles représentent aussi un moyen de lutte efficace contre les bioagresseurs, en particulier les adventices, par une compétition directe pour les ressources ou par des modifications du milieu de croissance. Le contrôle des maladies et ravageurs par les CIMS se fait... |

| 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,... |

| 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... |

| Enhancing plant-based diversity within agroecosystems may be an efficient way to achieve the objective of designing more resilient and low-input agricultural systems. The objectives of this study were (i) to describe the plant-based diversity practices implemented in organic or conventional agriculture in France and (ii) to identify the motivations of the farmers to apply such practices. It was also to compare the integration of such practices in organic or conventional farming systems. The survey was carried out in five French regions with 196 farmers that apply at least one plant-based diversification practice. Five diversification practices were studied: diversified crop rotations, use of catch crops, simultaneous intercropping, agroforestry and... |

| 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... |
