Nano Bio-Carrier with Plant Additives Combined with Chemical Fertilizers

Abstract

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.
