| Organic farming is based on to rely on a higher cropping systems diversity than its conventional counterpart and is regarded as one prototype to enhance the sustainability of agriculture and cereal-rich cropping systems. Nevertheless, organic arable crop rotations in temperate regions consist mainly of sole crops (SC; pure stands), with diverse pastures in farming systems with livestock being an exception (Hauggaard-Nielsen et al. 2001b). In organic farming, nitrogen (N) availability can be limiting especially in the absence of livestock (David et al. 2005ab) and causes cereal yield depressions and lower protein contents. For these reasons, integrating legumes with symbiotic fixation of atmospheric N2 is essential for balancing nitrogen exports from the... |

| Increasing concerns about environmental impacts and reduction of inputs require a transformation of current cropping systems for better efficiency and sustainability (Cox and Atkins 1979; Jackson and Piper 1989; Vandermeer et al. 1998; Griffon 2006). New agronomic solutions are needed including multiple objectives like i) yield, ii) quality, iii) provision of ecological benefits and iv) the adaptation of production systems to climate change. Organic farming is regarded as a prototype to enhance the sustainability of present cereal-rich cropping systems. Organic farming is in general assumed to rely on higher crop diversity than its conventional counterpart. Nevertheless, organic arable crop rotations in temperate regions consist mainly of sole crops (SC)... |
