    Patent number: 9321699
    Abstract: An oil-based coating for fertilizer granules impregnated with a polymer additive and related methods of applying the oil-based coating. The polymer additive can comprise homopolymers, copolymers, or combinations thereof, including polyethylene homopolymers. The polymer additive increases the viscosity of the oil-based coating, thereby increasing the duration for which the coating is capable of controlling or inhibiting the formation of dust particulates from the fertilizer granules.
