| Organic farmers are interested in adopting conservation tillage to preserve soil quality and fertility and to prevent soil erosion. Within the framework of a French national study, we compared conventional (ploughing) and conservation tillage systems in organic farming for arable and vegetable cropping systems. Field experiments and on-farm surveys were conducted in several regions of France in order to assess the effects of different tillage systems on soil fertility (physical, chemical, biological) and on weed and crop development. Conservation tillage techniques induced a more compact soil, an increase of carbon and microorganisms in the first soil layer, and an increase of earthworm biomass for very superficial tillage. Weed control was only a major... |

| The mineralization rate of a commercial organic fertiliser was evaluated over the course of three years in an organic rice field in the Camargue (France). The effect of different mounts of fertiliser applied at different periods was tested. The organic fertiliser rapidly mineralised under flooded conditions. On the basis of this result, we demonstrated that an adaptation of organic fertilisation practices, similar to those employed for mineral fertilisers, would result in the optimisation of organic fertilisers, leading to improved profitability. |
