Organic Fertilizer manufacturing Process: Return to nature, Nourish the Earth

In the development process of modern agriculture, organic fertilizer has attracted more and more attention and favor because of its natural, environmental protection and sustainable characteristics. The organic fertilizer manufacturing process is not only a science, but also a kind of reverence for nature and care for the land.

First, raw material collection and pretreatment
The manufacture of organic fertilizer begins with the collection of raw materials. Common organic fertilizer raw materials include livestock manure, crop straw, kitchen waste, green manure and so on. These feedstocks come from a wide range of sources, but require pretreatment before they can be used in the production of organic fertilizers.
Second, the fermentation process
Fermentation is the core of organic fertilizer manufacturing process. Through fermentation, the macromolecular organic matter in organic raw materials can be decomposed into small molecular organic matter, while killing the bacteria, eggs and weed seeds, and improving the safety and effectiveness of organic fertilizer.
Third, post-processing stage
After the completion of fermentation, the organic fertilizer also needs to be post-treated to improve its quality and stability. Post-treatment mainly includes drying, screening, granulation and other links.
Drying can remove excess water in organic fertilizer and improve the convenience of its storage and transportation. Screening can remove large particles and impurities in organic fertilizer to ensure uniform particle size of the product. Pelletization can process powdered organic fertilizer into granules, improving the convenience and uniformity of its application.
Fourth, quality testing and packing
Finally, the post-treated organic fertilizer needs to be tested for quality to ensure that it meets the relevant national standards and the needs of users. The quality detection mainly includes the detection of nutrient content, pH, heavy metal content, microbial index and so on.
