2. Preliminary treatment: Preliminary treatment of manure by fermentation or composting to decompose organic matter and reduce pathogens.

3. Mixing and blending: Mix treated manure with other organic materials (such as straw, food waste, etc.), adjust the carbon-nitrogen ratio, and optimize the fermentation environment.

4. Fermentation: Use professional equipment for composting and fermentation, control temperature, humidity and ventilation conditions to promote microbial decomposition activities.

5. Screening and drying: After fermentation is completed, screen the fertilizer to remove large pieces of incompletely decomposed substances, and dry it if necessary.

6. Maturation: Allow the treated fertilizer to further mature, stabilize the fertilizer properties, and enhance the fertilizer effect.

7. Packaging and storage: Pack and store the finished organic fertilizer for sale and application.
