Évaluation des effets des modes d'exploitation et de la fertilisation sur les quatre catégories de lombrics au sein d'un système polyculture-élevage

Abstract : Considering questions related to biodiversity has become a major political issue. Reconciling production and biodiversity has to be followed in the current economic and environmental context. Numerous charges about biodiversity loss have been made concerning mixed farming systems in France. This study aims to provide results related to the effects of agronomic practices on permanent grassland using the earthworms as an indicator. The analysis revealed that in the hay meadows and grazing, the contributions of mineral and organic fertilization favour anecic black head without influencing other ecological categories. Only within grazing conditions, the accumulation of mineral and organic inputs promotes the development of deep localized species (endogeic) at the expense of species living on the surface (growth control). Finally, in unfertilized grasslands, the abundance of earthworms is equivalent in grazed meadows only and in mowed and grazed ones.
