Abstract

Procedimiento para la preparación de productos fertilizantes, de actividad controlada, caracterizado en su realización porque consiste en extruir a través de un polímero termoplástico en uno o más medios líquidos, en presencia del 10-80% en peso con respecto al polímero de uno o más agentes fertilizantes, bajo condiciones de temperatura y presión tales que se produzca la evaporación casi instantánea de la fase líquida en el ambiente de extrusión.
