Abstract
Un método para la producción de un fertilizante de urea con azufre elemental a partir de azufre en estado líquido y un material fundido de urea líquida. Se influye sobre la tensión superficial entre las dos fases de azufre y urea en estado líquido a temperaturas superiores a los puntos de fusión, mediante el suministro de un aditivo que es estable a las temperaturas y anfótero, al material fundido líquido de azufre / urea de manera de obtener una fase mixta homogénea, que subsiguientemente se distribuye y solidifica. La presente también se relaciona con un fertilizante de urea-azufre en el que el fertilizante comprende urea y azufre elemental y un aditivo que es estable a las temperaturas y anfofero.
