1. Improve the quality of organic fertilizer: Organic fertilizer coating machine through the coating treatment of organic fertilizer, can improve the physical and chemical properties of organic fertilizer, make it more suitable for plant growth needs. The coated organic fertilizer is beneficial to plant absorption of nutrients, improve fertilizer utilization, and thus improve crop yield and quality. 2. Extend the fertilizer effect period: After the organic fertilizer coating machine is coated, the organic fertilizer releases nutrients in the soil more slowly and evenly, which is conducive to extending the fertilizer effect period. As a result, crops have a steady supply of nutrients throughout the growing season, which helps to improve yield and quality.

3. Reduce environmental pollution: The utilization rate of organic fertilizer after the organic fertilizer coating machine is high, which reduces the loss of fertilizer and the pollution of soil and groundwater. At the same time, the harmful gases such as ammonia nitrogen generated during the application of coated organic fertilizer are less, which is conducive to reducing greenhouse gas emissions and reducing environmental pressure.

4. Promote the improvement of soil ecology: the organic fertilizer treated by the organic fertilizer coating machine contains rich organic matter and microorganisms, which helps to improve the soil structure, increase the soil porosity, and improve the soil water and fertilizer retention ability.

5. Save resources: organic fertilizer coating machine helps to improve the utilization rate of organic fertilizer, reduce the dependence on chemical fertilizers, and save limited resources. This is of great significance for organic fertilizer production line to achieve agricultural sustainable development.

6. Improve economic benefits: The organic fertilizer treated by the organic fertilizer coating machine has good quality, large market demand, and can bring higher economic benefits.
