Abstract

La invención se relaciona con mezclas de fertilizantes que tienen un aspecto homogéneo y en las cuales las partículas de las mezclas defertilizantes han sido revestidas con 0,1-1% en peso de pigmentos y un método para colorear en forma homogénea dichas mezclas, el cual comprende revestir laspartículas del fertilizante con 0,1-1% en peso de pigmentos que comprendan pigmentos de sílice blanco que tengan un tamano de partícula de 0,1-1 micronesy una área de superficie de 100-550 m2/gramo y por lo menos un pigmento que tenga un tamano de partícula de 0,1-100 micrones y una área de superficie de10-100 m2/gramo y 0,0-0,5% en peso de aceite.En forma opcional el revestimiento puede contener 5-20% de la cantidad de aceite de un polímero o resina solubleen aceite. La proporción de pigmento de sílice blanco: pigmentosquetengan un tamano de partícula de 0,1-100 micrones puede ser de 1:3 a3:1.
