Why do we need dyes in fertilizer and pesticide?

Firstly, different kinds of fertilizer are designed into products in different colors, thus farmers can recognize them by color and find the corresponding formulas to different growth periods.

Secondly, the concentration of diluted fertilizer is hard to recognize without dyes. It can be a misleading to farmers.

Thirdly, many producers add tiny microelement or additives. In this way, they can tell if the mixing effect is ideal from the appearance. In this sense, pigment adding is an indicative means to produce high-quality fertilizer.
