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.

Controlled release fertilizers based on self-assembled molecule coatings

A coated fertilizer is provided along with a method for producing the coated fertilizer, where the coated fertilizer has a coating made of at least one amine compound which is a primary, secondary or tertiary, straight or branched hydrocarbon chain amine or an amine containing a cyclic hydrocarbon radical and; a microcrystalline wax, a paraffin wax or a soft synthetic wax.

Coating agent and coated particulate fertilizers

Free-flowing solid particles are dried in a moving bed dryer by passing the particles adjacent to a heat exchanger plate containing a heated fluid while passing a dehumidified gas into the solid particles from a gas flow manifold in the heat exchanger plate.
