Impact de la conduite des cultures intermédiaires sur la flore adventice : résultats de l’analyse de 31 essais
2022
Data of 31 field trials were analysed to quantify the impact of cover crops grown during summerfallow on weeds during this period. Results show that weed abundance at the date of cover-cropdestruction greatly varies between experimental locations which differed in terms of pedoclimate,previous crop etc. Cover-crop above-ground biomass did not impact weed plant density. However,weed above-ground biomass decreased with increasing cover-crop biomass. Cover-crop speciesgreatly differed in their ability to reduce weed biomass, according to their own biomass, their speedof soil coverage at early stages and their above-ground plant morphology. Cover crops with highlevels of biomass and rapid soil …

Structuration du territoire bourguignon : de l'île à l'isthme
2006
Three principles govern the structuration of the burgundian territory. Its internal organization, with the peripheral location of its most active areas, is similar to the organization of an island. Its situation within national and European space makes it an area of multiple transitions, an unsettled organization, submissive to strong centrifugal forces which can threaten its unity. Lastly, it has always been crossed by numerous links, it is an intermediate space between nodes, strongly marked with networks and exogenous traffic which criss-cross its territory.
