Beschreibung
Zusammenfassung:	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. Un recubrimiento a base de aceite con un aditivo polimérico para gránulos de fertilizante y los correspondientes métodos de aplicación del recubrimiento a base de aceite. El aditivo polimérico puede comprender homopolímeros, copolímeros, o combinaciones de los mismos, incluyendo homopolímeros de polietileno. El aditivo polimérico aumenta la viscosidad del recubrimiento a base de aceite, aumentando así el tiempo durante el cual el recubrimiento es capaz de controlar o inhibir la formación de partículas de polvo de los gránulos de fertilizante.
