The Origin of Iron Oxide Pigments Coloured Fertilizers
Agricultural chemical fertilizers produced according to standard chemical processes generally have an initial color of white (actually colorless and transparent). In order to label and identify the types and commercial quality levels of chemical fertilizers, different fertilizer manufacturers will add coloring processes to the fertilizer production process, resulting in the final production of commercial grade chemical fertilizers with specific coloring recognition. Famous examples include Canada's red potassium fertilizer and the "brown" American diammonium in the 1980s and 1990s
Especially in the United States, diammonium was once regarded by farmers as a "magic pill" for high food production. Due to the inability of other fertilizer practitioners in the world to produce diammonium of the same quality as American brands, many diammonium manufacturers have started using brown dyes. The rise of fertilizer dyes worldwide stems from this brown "magic". Later, fertilizer production in various countries around the world began to use dyes, and composite fertilizers and urea were also tempted. New types of fertilizers such as water-soluble fertilizers, controlled release fertilizers, and coated fertilizers also put on a colorful coat one after another.
The series of iron oxide pigments do not pollute the soil. As a fertilizer dyeing agent, the amount of iron oxide pigment used is very small due to its good dyeing effect. Moreover, iron oxide pigment is not a heavy metal and is not only non-toxic, but can also supplement the iron element lost in the soil and improve soil fertility.

Our GREEFIELD® iron oxide pigments are very suitable application for potash fertilizer, phosphoric fertilizer, organic fertilizer colorant usage. Our factory already exported to more than 6 countries fertilizers manufacturers and continuous good response at past 20+years.
