Depuis la seconde moitié du XXème siècle, l'utilisation massive des engrais desynthèse a contribué à l’augmentation des rendements mais aussi à l’accumulation d’élémentsminéraux dans les systèmes agricoles. La limitation de cette accumulation passe par unmeilleur recyclage des éléments minéraux déjà présents dans les systèmes agricoles.L'agriculture biologique, qui interdit le recours aux engrais de synthèse, peut être considéréecomme un prototype d’agriculture à même d’améliorer ce recyclage. L’objectif de cette thèse a été d’identifier les stratégies mises en place par les agriculteurs biologiques pour s’approvisionner en éléments minéraux. Cet objectif a été décliné en sous-objectifs qui ont été(i) d’identifier les pratiques d’approvisio...
