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.The invention relates to fertilizer mixtures that have a homogeneous appearance and in which the particles of the fertilizer mixtures have been coated with 0.1-1% by weight of pigments and a method for coloring in a homogeneous way said mixtures, which comprises coating the fertilizer particles with 0.1-1% by weight of pigments comprising white silica pigments having a particle size of 0.1-1 microns and a surface area of 100-550 m2 / gram and at least a pigment having a particle size of 0.1-100 microns and a surface area of 10-100 m2 / gram and 0.0-0.5% by weight of oil. Optionally the coating may contain 5-20 % of the oil amount of an oil soluble polymer or resin. The ratio of white silica pigment: pigments having a particle size of 0.1-100 microns can be from 1: 3 to 3: 1.
