  • Controlled released fertilizers based on self-assembled molecule coatings
    Publication number: 20030070462
    Abstract: Controlled release fertilizers are provided and methods for their preparation, wherein the controlled release fertilizers are obtained through self-assembling molecules on the surfaces of the fertilizer particles, and then, preferably, linking these molecules into a network with another component. The designed molecules have a hydrophilic portion, which can interact with fertilizers, and a hydrophobic portion that make the molecule self-assemble and setup a moisture barrier. The molecules also preferably have at least two functional groups in order to form a network.
    Type: Application
    Filed: November 13, 2002
    Publication date: April 17, 2003
    Applicant: MISSISSIPPI CHEMICAL CORPORATION
    Inventors: Zhongxin Ryan Ma, Donald R. Thomas, Corinne G. Ciaccio
