1. Reduce production costs: Automated organic fertilizer equipment can reduce manual operation, reduce labor costs, improve production efficiency, and thus reduce production costs.

2. Improve product quality: Through precise control of fermentation conditions, automated equipment can ensure the efficient decomposition and transformation of organic waste, improve the quality and stability of fertilizers, and increase the added value of products.

3. Resource recycling: Organic fertilizer production line can transform agricultural waste, livestock and poultry manure, etc. into organic fertilizer, realize the recycling of resources, reduce the pollution of waste to the environment, and create economic value for enterprises.

4. Efficient fermentation technology: advanced fermentation technology can shorten the fermentation time, improve the fermentation efficiency, reduce the production of harmful substances, and ensure the safety and environmental protection of fertilizers.

5. Improve soil quality: Organic fertilizer can significantly improve soil structure, increase soil water retention capacity and aeration, provide a good growth environment for crop roots, and improve soil fertility.

6. Reduce environmental pollution: organic fertilizer equipment can effectively treat agricultural waste and livestock and poultry manure, reduce odor gas emissions, improve the production environment, and reduce pollution to soil and water.

In summary, the demand for organic fertilizer equipment in aquaculture and agriculture is large, mainly due to the promotion of policy support, market demand growth, economic benefits and sustainable development, technological progress and innovation, and social and environmental benefits.
