What is fertilizer dyeing? Fertilizer dyeing has also become a fertilizer dyeing agent. Simply speaking, it is coloring fertilizers. It is also called “cosmetic†in the fertilizer industry. Now many manufacturers are gradually using dyes, such as our common compound fertilizers and water-soluble fertilizers. Fertilizers such as coated fertilizers are also dyed in different colors. So the question is, why should the fertilizer be added with dye? What is the role? Next, please see the knowledge points related to the amount of dye added in the fertilizer brought by Xiaobian.
First, why should chemical fertilizers be added?
Why do chemical fertilizers need to be added with dyes? Next, Xiaobian uses water-soluble fertilizer as an example to explain in detail. The details are as follows:
(1) Due to the large variety of fertilizers in the market and the same color, it is not conducive to farmers to identify fertilizers. By designing fertilizers into different colors, it is possible to quickly identify the type of fertilizer through color, and also reasonably correspond to each crop. Fertilizer formula that should be used at different growth stages.
(2) It is difficult to see the fertilizer concentration after dilution of the undyed fertilizer, and the dyed fertilizer can judge the fertilizer concentration by the color depth after dilution.
(3) Some fertilizer producers will add very few trace elements or additives to the fertilizer. It is necessary to judge whether the mixing effect of the fertilizer has a reasonable effect by the appearance of the fertilizer. The fertilizer additive is also a high-quality fertilizer. An indicative means.
Second, what kinds of dyes?
(1) Water-soluble dyes, pigments or oil-soluble colours.
(2) Naturally colored substances such as humic acid and certain polysaccharides.
(3) Inorganic pigments, such as iron oxide series dyes.
3. Is the amount of dye added to the fertilizer more or less?
(1) The amount of dye added to the fertilizer shall be used in accordance with the “Sanitary Standards for the Use of Food Additives†(GB2760).
(2) The dosage of fruit juice drinks, carbonated drinks, sweets and cakes is 0.1g/kg.
(3) The syrup is used for jam, fruit seasoning and mayonnaise, salad dressing, etc., and the maximum allowable amount is 0.5 g/kg.
4. Is the fertilizer stained with contaminated soil?
(1) Some people used dyes such as pyridine, enema, and disazo to dye the fertilizer, but few people have used it now.
(2) Iron oxide series dyes, one of the chemical products, are not polluted to the soil. The amount of iron oxide used in the dyeing agent is very small, and the iron oxide is not heavy metal. It is not only non-toxic, but also can replenish the iron lost in the soil.
