Abstract

The coating of soybean seeds with bacteria and micronutrients favours the vigorous growth of the plant, dispensing with the use of ammoniacal fertilizers. The optimum thickness of the coating should allow the fundamental gaseous interchanges for the germination and the ideal conditions for the activity of the bacteria. The objective of this work was to simulate dynamic mass distribution of soybean seeds covered with bacteria and macronutrients in spouted bed through a specific program developed in Maple V®. The validation of the model is done through 16 experiments carried out in a spouted bed with spray at the top.

Abstract

L'enduction de graines de soja par des bactéries et des micronutriments favorise une croissance vigoureuse des plantes, ce qui dispense de recourir à des fertilisants ammoniaqués. Une épaisseur optimale de l'enduit devrait permettre les échanges gazeux de base nécessaires à la germination et correspondre aux conditions idéales pour l'activité des bactéries. L'objectif de ce travail est de simuler la distribution en masse dynamique des graines de soja recouvertes de bactéries et micronutriments dans un lit jaillissant par un logiciel spécifique mis au point dans Maple V®. La validation du modèle est réalisée par seize expériences menées en lit fluidisé avec atomisation par le sommet.
