How to identify the quality of water soluble fertilizer in life? Look at the formula, water-soluble fertilizer is actually a formula fertilizer, according to different crops, different soils and different water quality to formulate different formulas, in order to meet the nutritional needs of crops, improve fertilizer utilization, reduce waste, so the formula is to identify water-soluble fertilizer Bad key. Looking at the content, good water-soluble fertilizers use industrial-grade or even food-grade raw materials, which are of high purity and do not contain any fillers. Therefore, the contents are relatively high, and 100% of them can be absorbed and utilized by crops. Substance, nitrogen, phosphorus and potassium content can reach 60% or even higher. Poorly water-soluble fertilizers are generally low in content, each one less in content, the cost will be different, and the price of fertilizer will be different. To see the water solubility, to identify the water solubility of water soluble fertilizer, it is only necessary to dissolve the fertilizer into clean water to see if the solution is clear and transparent. If the color of the fertilizer is the same as that of fresh water, the water solubility is good; if the solution is turbid or even precipitated, the water solution The sex is very poor and cannot be used in drip irrigation systems. The waste of fertilizer will also be more. Smell, good water-soluble fertilizers are made from high-purity raw materials, without any taste or with a very light fragrance. The odor of the fertilizer is either the addition of hormones or too many harmful substances. This kind of fertilizer works quickly, but it does not have any benefit to the disease resistance and the continuous yield and quality of the crop. For comparison, after the initial screening of water-soluble fertilizers by the above simple methods, the comparison is then done in the field, and what kind of water-soluble fertilizer is selected by the actual application effect. Good fertilizers will not work quickly because nutrients have a process of absorption and transformation. The use of good water-soluble fertilizers for two or three times will show obvious differences in plant growth, crop quality, crop yield, and disease resistance. The greater the frequency of use, the greater the difference. The tamper holograms are made of advanced quality materials and adhesives. The tamper evident Hologram Labels has appealing appearance and offer security protection to the brand.

If any individual tries to remove the tamper holograms after they are sticked on, this results into separation of the uppermost layer of the film. In this case, the tamper evident holograms shows the tampering.
To meet various industrial safety and identification requirements, these holograms can be customized in different sizes, shapes, design and color combinations.
