Les conditions pratiques d’un engagement économique et moral. Les maraîchers biologiques et la saisonnalité des fruits et légumes

This article deals with social mechanisms which produce normative choices of organic market gardeners, treating mainly two aspects of farm working which are significant of their relationship to production seasonality: greenhouses and commercialization. It describes and tries to explain two distinct phenomena: the variation of productive norms from one farm to another, and the evolutivity in time of these norms. These two phenomena bring us to a better comprehension of commitment (and disengagement) in favor of production seasonality “respect”.
