Quels enseignements d'études sur prairies permanentes mobiliser pour implanter et gérer les prairies plurispécifiques ?

Abstract : Recent studies, associating approaches taken from functional ecology and traditional agronomical processes, have resulted in significant progress in the way multi-specific permanent pastures can be characterized. In this paper we put forward the notion of functional plant types, which are identified on the basis of common biological features and by their links to the agricultural characteristics of the species; these characteristics are those that define the use value of the pasture. The results from many studies, with a vast array of experimental designs (collection of native species, fertilisation trials, network of experimental plots on individual farms) show the existence of stable relationships between the types of dominant species in a pasture and the methods of management (intensity of defoliation and fertilisation). These results are discussed in view of an application to pastures with a complex floristic composition. Suggestions are made concerning the rules for the association of species and the methods of management to apply in order to ensure the perenniality of the pastures after sowing.
