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.
