Bio-organic fertilizer is decomposed at high temperatures, has high nutrient content, is rich in beneficial bacteria, has high utilization rate and good effect, and is favored by fruit farmers. The effective living organisms of bio-organic fertilizer can not be seen and touched. From the aspect of product appearance, it is no different from common organic fertilizer. How to distinguish authenticity?
Judging from the packaging 1. Check whether there is a microbial fertilizer registration certificate issued by the Ministry of Agriculture on the packaging. The registration of bio-organic fertilizer products was conducted at the Ministry of Agriculture's Microbiological Fertilizer Registration Center, and a fertilizer registration certificate was issued by the Ministry of Agriculture. The certificate number registration method is "microbial fertilizer (registration year) Pro word (number)" or "microbial fertilizer (registration year) standard (number)". 2. Check whether the number of valid live bacteria is marked on the package. If not, it is fake and shoddy products. 3. Check that the packaging is marked with the product's production date and expiration date. Because the special functional strains in bio-organic fertilizers are alive and alive, it is not the user's responsibility to mark the product's valid period too long. 4. You can go to the relevant website of the Crop Management Division of the Ministry of Agriculture to inquire.
To see if the product is too uniform or too low in water content is not conducive to the survival of bacteria species. Judgment method: grasping a handful of fertilizers in the sun to observe, ascending tide group, dry ash are not normal products. The "organic nutrients" suitable for the growth of special functional strains should be packaged and consist of a variety of organic nutrients (eg fermented rapeseed, soy flour, etc.), visible in the light, or Smell the special smell of raw materials.
A look at two other things, some of the user's experience can also learn from. A look: High-quality bio-organic fertilizer is generally made from high-quality chicken manure as its raw material, with high nutrient content, relatively loose, and dark brown color. The inferior organic fertilizer is generally black and not loose enough. Two bubbles: Authentic granular organic fertilizer will dissolve in water in a short time, the color is gray, but there is no impurity; false there will be a lot of impurities that are insoluble in water. Sanzhao: Put a small amount of organic fertilizer on iron plates and place it in a fire source. In a short time, the genuine products will be smoked and coking, and there will be very few residues; false will leave a lot of residue.
