Article
Lengthening and diversifying crop rotations is an efficient strategy to reduce the use of fertilizers and pesticides, thereby improving the sustainability of cropping systems. To test this assumption, six innovative cropping system prototypes were designed, each introducing one or more agroecological practices, as alternatives to the 2-year sunflow...

Article
Agriculture contributes to a significant proportion of global emissions of greenhouse gases (GHG) but can also participate in climate change mitigation. The introduction of legumes in crop rotations reduces the dependence on N fertilizers and may mitigate the carbon (C) footprint of cropping systems. The aim of this study was to quantify the C foot...
Conference Paper
See Page of the Proceedings The optimization of cash crop successions and rotations is crucial for designing efficient cropping systems providing supporting ecosystem services instead of using external chemical inputs. The reintroduction of legumes is a relevant means for increasing the nitrogen resources. The interests of legumes are well known, h...

19 prototypes de systèmes de culture ont été testés sur quatre sites contrastés (Picardie, Bourgogne et deux sites dans la région de Toulouse). Ces systèmes de grandes cultures ont été conçus selon les principes de Protection Intégrée pour limiter l’usage des pesticides en général et des herbicides en particulier. Les combinaisons de leviers altern...

Sunflower (Helianthus annuus L.) crop is often labelled as environmental-friendly for many objective reasons: limited amounts of N fertiliser, no irrigation, and limited use of pesticides. In addition, sunflower has a potential for providing multiple ecosystem services in diverse cropping systems (e.g. pollinators feeding). However agroecological i...
Article
Inserting legumes in low-input innovative cropping systems can represent a good strategy to reduce current N fertilizer dependency while enhancing ecosystem services. However, although the impact of the use of legumes as cover crops has been broadly studied, very little is known about the effects of grain legume-based rotations on soil organic carb...

Six cropping systems (CS) of three 3-year rotations based on durum wheat and sunflower inserting 0, 1 (pea or fababean) and 2 grain legumes (GL) (pea and soybean), and with or without cover crops (CC) were compared at INRA Toulouse from 2004. This experiment is still on going for a twelfth year. We demonstrated that 6 key points. 1) Pea as a preced...
Article
The reduction in crop diversity and specialization of cereal-based cropping systems have led to high dependence on synthetic nitrogen (N) fertilizer in many areas of the globe. This has exacerbated environmental degradation due to the uncoupling of carbon (C) and N cycles in agroecosystems. In this experiment, we assessed impacts of introducing gra...
Article
A generic approach is proposed for the development and testing of crop management systems in contrasting situations of water availability. Ecophysiological knowledge, expertise, regional references and simulation models are combined to devise management strategies adapted to production targets and constraints. The next stage consists of converting...

Cover cropping is an efficient way to produce ecosystem services (reduction of nitrate leaching and recycing N; C storage; reduction of soil erosion; etc.) by replacing the use of pesticides (fertilizer-N and some pesticides). Cover crops and catch crops constitute one of the pillars of the application of agroecology in arable cropping systems.
