A multi-site study to classify semi-natural grassland types
International audience; Calibration and validation of simulation models describing herbage growth or feed quality of seminatural grasslands is a complex task for agronomists without investing effort into botanical surveys. To facilitate such modelling efforts, a limited number of grassland types were identified using a functional classification of species. These grassland types were characterized by three descriptors required to model herbage growth or feed quality: the abundance-weighted mean leaf dry matter content across grass species, the relative abundance of grasses, and an estimate of species richness. We conducted a multi-site analysis over 749 grasslands from eight temperate region…

Gestion du pâturage au printemps en système bovin allaitant : diversité des pratiques en Saône-et-Loire
National audience; Grazed grass is the cheapest forage for making meat'. In order to incite farmers to make their forage systems more self-sufficient and thrifty, the 'Chambre d'Agriculture de Saone-et-Loire' (a professional agricultural organization for that departement) has been monitoring for five years the management of spring grazing on 23 farms. The analysis of farmers' practices lead to considerations as to put to the best use the grazed grass, according to the pedo-climatic conditions and the constraints of the farms. With the aim of optimizing the pasture resources in order to limit the purchase of concentrates and to cope with the climatic hazards, the study of the management of s…
