Abstract

Esta invencion se relaciona con la encapsulacion de fertilizantes con poliuretanos, donde la composicion reactiva a isocianato contiene azufre. El procedimiento de la presente invencion consiste en aplicar una composicion de poliisocianato a particulas de fertilizante, aplicar una composicion reactiva a isocianato que contiene azufre a las particulas de fertilizante revestidas de poliisocianato o aplicar una composicion reactiva a isocianato que contiene azufre a las particulas de fertilizante y aplicar despues una composicion de poliisocianato a las particulas de fertilizante revestidas con la composicion reactiva a isocianato, y repetir estas etapas segun sea necesario para formar particulas de fertilizante encapsuladas en poliuretano que contienen azufre.
