Abstract

L'invention concerne des procédés et un système visant à renforcer la solubilité dans l'eau et la disponibilité du zinc dans des engrais granulaires à l'aide de traitements à l'acide. Le traitement d'engrais granulaires à l'aide d'une solution acide entraîne une augmentation de la quantité de zinc soluble dans l'eau, ce qui, à son tour, renforce l'efficacité d'absorption du zinc et réduit les coûts et l'équipement qui, sinon, est nécessaire pour remédier aux carences en zinc.
