L'enherbement comme mode de gestion du rang et de l'inter-rang en verger de kiwis

Abstract : Soil is a non-renewable resource. To protect it and avoid loss of functionality, arborists must look after it. The current policy context aims to eliminate glyphosate, used until now to limit weeds on the row in 80% of orchards. Permanent grassing would be a possible alternative to herbicides. A survey was launched in March 2020 and semi-structured interviews were led in the spring. After analysing the responses of the 44 arborists, a range of opinions on the issue emerged. While some see glyphosate as an effective molecule, which they will find difficult to do without, others are already grassing their entire plot. For proper row maintenance, the grass should be either very low or not existing. On the other hand, if the soil is bare (mud, rut) the inter-row is considered "dirty". To establish a cover, the constraints on the row are more important than on the inter-row: lower luminosity, more intense trampling. It is therefore normal that the flora is different since it is not subject to the same pressures. A trial started at the end of May in the Adour valley.
