To select organic fertilizers for industrial production, one must ask “one question, two opinions, and three investigations”.

1. Ask the source of raw materials. Raw materials are the prerequisite for determining the quality of organic fertilizers. It is not advisable to produce organic fertilizer by directly mixing only livestock and poultry manure as raw materials. Although it contains a large amount of organic matter, due to the intensive cultivation of livestock and poultry, some feed may also cause pollution to the soil and water due to livestock and poultry, posing a hidden danger to food safety. Substances, such as heavy metals, antibiotics, and harmful bacteria, need to be detoxified.

Recommended raw materials are: animal protein, such as industrial processing of animal residues, fur, etc.; vegetable protein, such as oil withered, soybean meal residue.

2. Second look at the manufacturing process. See if the raw materials used are fully fermented and decomposed, whether beneficial biological bacteria are added, whether they have sustained-release, controlled-release long-acting, whether they will avoid volatilization and reduce fertilizer efficiency, whether there are other special effects, and whether there will be excessive acid, alkali, Salt and other substances that cause hidden damage to the root system, whether the package is standardized, etc.

3. Check inspection inspection report. Whether the raw materials and finished products meet the industry standards and national standards, whether it has obtained the test report of the national authority. In particular, we must pay attention to whether heavy metals such as lead, cadmium, chromium, arsenic and mercury are excessive, whether harmful bacteria exceed the standard, whether there are other toxic and hazardous substances, and whether the government obtains an official fertilizer registration certificate issued by the relevant government functional departments. .
