Abstract[English]
Disclosed herein are fertilizer compositions formed by a method comprising reacting an aqueous polysaccharide and cross-linking agent to provide a polysaccharide polymer scaffold; reacting the polysaccharide polymer scaffold with a plant additive under conditions effective to form a polysaccharide nanocomposite; and combing the polysaccharide nanocomposite with a urea fertilizer to form an aqueous urea-polysaccharide nanocomposite solution; and evaporating or freeze drying the urea-polysaccharide nanocomposite solution to provide a urea- polysaccharide nanocomposite. The urea-polysaccharide nanocomposite may be applied to soil as the fertilizer composition.[French]
L'invention concerne des compositions d'engrais formées par un procédé comprenant la réaction d'un polysaccharide aqueux et d'un agent de réticulation pour fournir un échafaudage de polymère de polysaccharide ; la réaction de l'échafaudage de polymère de polysaccharide avec un additif végétal dans des conditions efficaces pour former un nanocomposite de polysaccharide ; et la combinaison du nanocomposite de polysaccharide avec un engrais d'urée pour former une solution nanocomposite aqueuse d'urée-polysaccharide ; et l'évaporation ou la lyophilisation de la solution de nanocomposite d'urée-polysaccharide pour fournir un nanocomposite d'urée-polysaccharide. Le nanocomposite urée-polysaccharide peut être appliqué au sol en tant que composition d'engrais.
