Abstract

Une matrice de revêtement a été développée pour améliorer la qualité et l'efficacité desengrais granulaires, des minéraux granulaires et des engrais hydrosolubles. La matricede revêtement est un extrait végétal tel que des microalgues ou macroalgues appeléesalgues. Une étape de modification chimique a été ajoutée pour développer unepropriété viscoélastique afin former un film. Cette propriété est utilisée pour couvrir lesparticules telles que les engrais granulaires ou les' minéraux. Ce film a amélioré laqualité des granules du transport à la livraison. Les engrais, les minéraux ou toutesautres particules pourraient être granulés tels que le tri-superphosphate (tsp), lephosphate monoammonique (map), le phosphate diammonique (dap) et l'azote (n), lephosphore (p), l'urée, le potassium, npk, et la silice. La matrice de revêtement estmélangée avec des engrais solides ou liquides et 1 ou des pesticides. La matrice derevêtement joue également un rôle stimulant de croissance des plantes. Elle est utiliséecomme biostimulant ou ajoutée à d'autres nutriments. Elle est appliquée seul oumélangée avec des macro et 1 ou des micronutriments solides ou liquides. Lesmicronutriments contiennent par exemple le zinc, le fer, le sodium, le calcium, lemagnésium, le manganèse etc.Abréviations: tri-superphosphate (tsp), le phosphate monoammonique (map) du lephosphate diammonique (dap), l'azote (n), le phosphore (p) et le potassium (k)appelés npk. Kilogramme force (kgf), centpoise (cp). Poids d'échantillon demi-sec(pds). Le profil des acides gras (fa). Poids sec (sw). Acide indole-3-acetique ou auxine(iaa). Indole-3-butyric acid (iba).
