Is the powdered biological fertilizer is true? Experts said that there is no such statement. Some netizens said that a few days ago, a bio-fertilizer manufacturer went to the village to give lectures, saying that all the bio-fertilizers of powders are true, and all the granular bio-fertilizers are fake. Because the fertilizer will go through high temperatures during the granulation process, the high temperature will kill the microorganisms. Is this true? This reason is very confusing, so that people who are unclear believe that it is true, and it has a bad influence on the manufacturers who distribute the granular bio-fertilizer.

There are powders and granules in organic fertilizers. Some organic fertilizers are produced at high temperatures, but please note that the process of producing granular bio-organic fertilizers at high temperatures does not place the strains before the high-temperature stage, but instead After the high temperature link. That is, after high-temperature granulation, the microbial agent is sprayed on the surface of the granules, which ensures that the granule bio-fertilizer is both granulated and maintains the survival rate of the strain.

In addition, the production process of the granular fertilizer does not need to go through high temperature, such as disk granulation, extrusion granulation and the like. These physical granulation processes directly add microbial bacteria to the powdery organic matter, and do not destroy the activity of the microbial bacteria after granulation.

It is a completely feasible and mature process to add granules after granulation and granulation without high temperature. There is no granule microbial agent is false, powdered microbial agents are true. .

In the national microbiological fertilizer implementation standards, it is allowed to produce granular microbial fertilizers. For example, the implementation standard of "Bio-organic Fertilizer" stipulates that the powder product should be loose and have no bad odor; the granular product should have no obvious mechanical impurities, uniform size and no spoilage.

The implementation standard of "Compound Microbial Fertilizer" stipulates that the product is divided into liquid, powder and granular according to the dosage form, and the powder product should be loose; the granular product should have no obvious mechanical impurities, uniform size and water absorption. The implementation standards of "Agricultural Microbial Inoculants" stipulate that products can be divided into liquid, powder and granular according to the dosage form.

Judging from the above national regulations, it is said that the microbial fertilizer of the powder is a true, granular microbial fertilizer is fake, purely illusory.
